See chart below for the equinox and solstice dates and times for 2015.

Why do the seasons change? The four seasons are determined by shifting sunlight (not heat!)—which is determined by how our planet orbits the Sun and the tilt of its axis.

  • On the vernal equinox, day and night are each approximately 12 hours long (with the actual time of equal day and night, in the Northern Hemisphere, occurring a few days before the vernal equinox). The Sun crosses the celestial equator going northward; it rises exactly due east and sets exactly due west. See our First Day of Spring page!

  • On the summer solsticewe enjoy the most daylight of the calendar year. The Sun reaches its most northern point in the sky at local noon. After this date, the days start getting "shorter," i.e., the length of daylight starts to decrease. See our First Day of Summer page!

  • On the autumnal equinoxday and night are each about 12 hours long (with the actual time of equal day and night, in the Northern Hemisphere, occurring a few days after the autumnal equinox). The Sun crosses the celestial equator going southward; it rises exactly due east and sets exactly due west. See our First Day of Fall page!

  • The winter solstice is the darkest day of the year when the Sun reaches its most southern point in the sky at local noon. After this date, the days start getting "longer," i.e., the amount of daylight begins to increase. See our First Day of Winter page!

Retired people make the trip annually to escape winter & love how cheap it is economically!
They are known as TROPICAL & known to Bird Watchers around the world!

South Padre Island (Not to be confused with Padre Island in Corpus Christi).
SOUTH Padre Island is located 3 more hours further South than Corpus Christi.
South Padre Island is located in the Rio Grande Valley. Mexico runs along HWY 281 & Progress Mexico is wonderful to shop at for authentic Mexican jewelry, furniture, decorations, food, adult beverages, alcoholic bottles, cheap medications, etc! Try going there this or next winter, try it out!

Texas, Tropical? Not quite, though So Padre could be considered sub tropical. Last I heard there were a bunch of "Patriots" in Texas talking about succeeding from the USA so I quit doing any business with them, I don't even fly over it anymore, I go north through Oklahoma (I'm afraid if I crash in Texas I might Survive!). Saying you can buy much of anything Authentic in a border town is just about Tourist/Gringo crazy. Go to San Miguel De Allende Queretarro or Puerto Vallarta, maybe Veracruz and you might find authentic, I'm Just Sayin.

Two month hurricane season?

By Buzzkill

Two month hurricane season?


I was seeing some total BS on the weather channel the other day making COMPLETELY FALSE CLAIMS like that and was wondering how they can get away with it.

The Atlantic hurricane is "officially" 6 full months. In reality though, it's closer to 8 or 9.

I lived in Florida for 5 years. Non-stop oppressive heat for 9 months a year. Nothing like spending Christmas morning with the AC going full blast.

It's nothing like west coast "heat". 90 degrees "caribbean" heat is like the about like 110 degrees of west coast heat.

Nobody "likes" it. You just have to try to endure it.

Not sure what "BS" you are

By Bill the Meteorologist

Not sure what "BS" you are talking about hearing on the Weather Channel, BuzzKill, but perhaps they were explaining that the PEAK of the Atlantic hurricane season is August through September, with the peak day being September 11th. The season OFFICIALLY runs from June 1st through November 30th (6 months), but there have been tropical storms or hurricanes recorded somewhere in the Atlantic at some time in all months of the year except February and March. However, tropical systems outside of the normal 6 month season are rare, and they do not usually affect any land masses. Hope that clears things up for you, BuzzKill.

By CookieAuntie

Lived through one of those out of season tropical storms. Wasn't bad. In fact, I slept through the whole thing. Guess that was the up side of having my bedroom face inland. It was a bummer for Ana to arrive the first weekend we were vacationing along the NC coastline. Had relatives who didn't want to stop by because of it.

I lived 23 years in the Caribbean Island of Puerto Rico! Here we have 2 seasons:Wet and Dry! The wet season is actually also Hurricane Season (June-November). Florida is way different than the Caribbean. My father lives there and in Christmas is a little cold for my taste. Right now is 86 degrees here and I just have a fan on. In December, I actually don't need to turn the fan on, just open a window! I can go to the beach almost all year long and I love it. The only complain I have is the humidity levels, other than that is Paradise!

“Dogwood Winter” refers to a spring cold snap that usually comes around the time when the dogwood trees start to bloom. The flowering dogwood tree (Cornus florida) blooms in April and May.

Why would the seasons start

By crezeeman

Why would the seasons start at the middle? Isn't solstice the MIDDLE of summer and winter? I certainly would never think of December as being mostly an autumn month. It is entirely within the winter season. So here is scientifically correct: 365.24218967/4=91.310547417
So spring starts exactly 45.655273708 days before spring equinox, summer starts 45.655273708 days before summer solstice, etc, etc...
We can get more accurate than this but I think we get the point. Today is NOT the first day of spring. And Who the hell believes winter starts only days before Christmas?! We're already balls deep into winter by then!

You want your winter season

By CurtW

You want your winter season to start Nov.06?
If you're balls deep into winter by Dec.21,
I bet you're still neck deep in winter on Feb.05!
March 21 weather is about like Dec.21 weather, depending on how much surface water is around (lake effect ...), so the astronomy festivals are appropriate markers for the seasons' start.
Unless (like olde England) you want mid-Summer to be the "fastest-rising Temperature" etc.

When you talk about seasons,

By Lucius Germanus

When you talk about seasons, you are either talking about hours of sunlight in a day OR you are talking about your feelings about weather and what constitutes a season. I understand what you are saying, but there are a couple of problems. First problem is that there is a lag between the changing hours of daylight and the changes it causes in the weather. So, where i live in Kentucky, what i would consider the peak of summer is definitely well after June 21. Using your system fall has started by Aug 7. Which is often the hottest time of year here. In fact if you forget math and just write down the dates of when you FEEL that seasons begin and end, you will find that they are not at all equal lengths. I lived in Colorado one year and I swear it was winter for seven months with the other seasons covering the remaining five months. I understand your point and it makes some sense if you are talking ONLY about the number of hours of sunlight in a day. However, this has nothing at all to do with how you FEEL about when fall starts and ends or whether or not you have snow on your balls in March.

Our seasons are marked by

By Peter Metzler

Our seasons are marked by changes in the intensity of sunlight that reaches the Earth's surface, variations of which may cause animals to go into hibernation or to migrate, and plants to be dormant. Our sense of time, as determined with our calendar is more politically determined and does not conform with nature.

December; January; February. = Winter.

March; April; May. = Spring.

June; July; August. = Summer.

September; October; November. = Autumn.

Actually, it takes from

By BrunoK

Actually, it takes from january to august to heat up (7 months) but only from august to january to cool down again (5 months). So, weather speeking, spring is actually longer than autumn. Season arent realy the same lenght, its just a simplification.

Plus, i agree with the offical summer months. Weather its warmer and show less rain between the 2nd half of june and the 2 nd half of september. The begining of june its colder and more instable then the beging of september.

So, with the data i have seen, the real weather seasons are:

21 Nov to 21 Fev = Winter (3 months)
21 Fev to 21 Jun = Spring (4 months)
21 Jun to 21 Sep = Autumn (3 months)
21 Sep to 21 Nov = Winter (2 months)

When they say, for example, this was the wettest spring they mean the calendar months March, April and May.

Where ever you are, if sun is

By kasun

Where ever you are, if sun is on top of you at high noon, that is the day summer starts to that place and so on. Though people try to, for convenience sake, it is not possible to standardize most of the happenings of nature. Things go wrong when you try to think like that. Convenience vs Accuracy.

The seasons are determined by

By Adam Steidl

The seasons are determined by the relative angle of the Earth to the Sun. This does not necessarily mean that after the Vernal Equinox it will suddenly be warm and flowerly and spring-like. It just means that the days will get longer in the Northern Hemisphere, and shorter in the Southern Hemisphere. Historically, since the last ice age, anyway, days start getting warmer after the Vernal Equinox, except in extreme locations, like on top of mountains, or in deserts, or near oceans.

The "days" getting longer and

By Sherry McCoy

The "days" getting longer and the "nights" getting shorter does not begin, however, at the Vernal Equinox. That trend begins at the Winter Solstice and continues until the Summer Solstice.

On www.almanac.com the starting dates of the seasons is given and reason for them, and also why different seasons start at different times and dates based on the time zone you're in, etc., and if you want to try experiments like balancing an egg on the vernal equinox or some other eqinox, etc., I would suggest 1st checking for the 1st day of this year's seasons as well as equinoxes which are not on the 1st day of each season, at www.almanac.com, and then for the Southern (Austral) Hemisphere's seasons just re-label the 1st day of the summer as the 1st day of winter, following season is Spring, etc. You could also Google: 1st day of the seasons 2014, etc, at www. google.au

G’day, I’m an Aussie born and bred. In Australia the official first day of summer is December 1st, autumn March 1st, winter June 1st and spring September 1st. In this country the Equinoxes are just that and nothing more, likewise the Solstices.

In Australia, you are right,

By So am i Aussie born and bred

In Australia, you are right, it is a common to say that the seasons start on the first of the equinox month. But that is because it is spoken by purveyors of ignorance. Anyone sweating through a 30C+ day well into March would hardly say we are having Autumn weather. The 'seasons' are far more closely aligned to the equinii, all around the planet, including Australia. Shameful that many students in school here have no idea what makes a season, other than a date rolling over to the first of the month. Thankfully the idea of seasons is slowly changing here, to be more in line with how the rest of the planet undertand them to be.

By Rick Middleton

Does anyone else find it a bit weird to call tomorrow the "first day" of Summer. Since it marks the end of the lengthening of daylight it really is the middle of the warmer half of the year (in the n. hemisphere) even though it usually gets hotter over the next two months in that hemisphere. And do we really have four seasons? Our year is really more correctly thought of as biphasic instead of quadriphasic: a warmer half and a cooler half. I realize that the way we name our seasons long predates our understanding of the reason we have seasons and it is more fun to anticipate a seasonal change in quarters rather than halves but it isn't really based on rationality--and that's okay, too. There, I've put my two cents in.

It is long overdue to do away with the counting of time on the basis of the Holy Roman Empire Anno 2013. With all the high tech, instant coffee and archeological findings the Collective Mind still is bullied by religions spearheaded by the Vatican. It would be a great advancement for our grandkids when the Collective Mind would show higher awareness and determine a point of substance on which basis to count time instead of the Holy Roman Empire. Quadriphasic keeps you on your toes for harvesting.

My thoughts exactly - why is the summer or winter solstice the Beginning of that season? Shouldn't it mark the mid-point? How can it be that Winter in the S Hemisphere starts on the 21 June Winter Solstice when immediately after that point the days start getting longer? Doesn't make sense to me.

By paulfrogprince

You're spot on. Somebody told me that 21st June is the first day of Summer. I said, "Where?" They replied, "Everywhere!" I think Australians would beg to differ! But it got me thinking. Taking into account all the astronomical, geographical, longitudinal, latitudinal,oceanic, climatic and meteorological variables, every day must be the first day of summer somewhere in the World? Strange how easy it is for most people in the World to believe that the exact opposite is true? I think that might be 3 cents worth. Sorry!

The dates for the beginning

By Marie Mayer

The dates for the beginning and end of months are based on the Gregorian calandar. If you go further back to the more pagan calandars, you'll find that the dates that are currently used for beginning/end of the seasons were actually the middle.

The beginnings were Samhain (October 31), Imbolc (February 2), Beltane (May 1), and Lughnasadh [Lammas Day] are the beginning.

The middle of the seasons are Yule/[Christmas], Ostara[Easter], Midsummer, and Mabon[Mid-Autumn]

Hi Rick, in Australia we're in the 1st month of winter. Our 'seasons' officially start: winter, 1st June; spring, 1 September; summer 1 December; Autumn (fall) 1 March.

By Rick Middleton

Cate, glad to hear from "down under" (another northern conceit, though, isn't it; who decided the s. hemisphere is the "bottom" anyway?). By official start, I assume you mean by arbitrarily agreeing to call it so rather than based on the way the planet is moving along in its orbit, right? It doesn't suddenly get cooler on June 1, does it?

Yep, it's just an arbitrary date. Most people realise that it doesn't really start changing temperatures until the solstices/equinoxes.

By Rick Middleton

But, really, none of the calendar dates for what we call the seasons is associated with any kind of sudden temperature change. At the Autumnal equinox, maple leaves don't suddenly turn red. We basically move gradually between warm weather to cool weather to back again over and over. The idea of four separate, distinct seasons is really related more to social customs and human activity like agriculture (for planting, growing, harvesting and fallow times) isn't it?

There is a great site that

By Indenim

There is a great site that details the actual progress of the seasons as based on the quarters and cross-quarters: http://www.archaeoastronomy.com/ - it also provides an animated star clock that shows where we currently are in the orbit of the earth as of today and the tilt of the earth as it progresses through the orbital cusp point. Also, it was earlier mentioned that the tilt of the earth's axis is 23.5 degrees - that is incorrect - the current tilt of the earth's axis (as of mid-2013) is 23.439 degrees. The tilt of the earth's axis is affected by many factors, some regular and predictable (related to the precession of the equinoctes and the effecct of lunar gravity) and others unpredicatble (e.g. redistribution of mass due to earthquakes) - for instance, the great earthquakes of 2004 in the Indian Ocean basin and in 2011 at Japan in the Pacific Ocean basin actually slightly affected the tilt of the earth by moving larges masses of the Earth's material closer to the centre of the Earth. The Earth's axial tilt is currently decreasing, and may vary between 22.1 and 24.5 degrees. It is postulated that when the Earth's tilt is at the maximum point of 24.5 degrees is when ice ages typically occur - and as well, ice ages also have an effect on the axial tilt, since they redistribute large amounts of mass (i.e., ice) towards the geographic poles. The after-affect of this mass redistribution is still being felt due to crustal rebound of areas of the Earth that were under massive volumes of ice during the most recent ice age (for instance, the Hudson Bay basin in Canada is currently rebounding by close to 2cm per annum due to the removal of the Laurentian ice sheet following this most recent period of global climate warming [unrelated, BTW, to any human-induced warming of the climate]).

By Lynda Crossley

Thank you so much for the educated answer on the tilt of the earth. I knew the earth changed it axis recently but did not know it was linked to major earthquakes. I will be visiting the website you suggested. Great explanation. I too live 'downunder' and yes our date for the beginning of seasons is different to the north. Does anyone know the history of this fact?

The astronomical definition

By Almanac Staff

The astronomical definition of when a season begins (such as the March equinox: spring in the Northern hemisphere; fall in the southern) applies everywhere around the world (a set point in time, converted to local time zone).

However, different countries may celebrate the seasons at different times. For example, in Bulgaria, March 1 is often celebrated as the beginning of spring. Also on March 1, Helidonismata is a traditional Greek observance that celebrates the return of the swallows, marking spring's return, as well.

You might also be interested in Greek mythology as it relates to spring: the story of Demeter and Persephone.

the references to 'the longest day' and the 'shortest day' is in error. Each day of the year consists of 24 hours--it's the length of daylight hours that varies! I recommend you change the word day to daylight in order to be accurate.

Is Dec. 21, 2012 the first day of winter 2012 or the first day of winter 2013? Didn't we go through the winter of 2012 back in January of this year? So on March 20th, 2013 (the first day of Spring 2013) will we have just finished the winter of 2012 or the winter of 2013? Please clarify.

As you've noticed, the winter

By Almanac Staff

As you've noticed, the winter season spans the end of one year and the beginning of the next in the Gregorian calendar. December 21, 2012, at 6:12 am EST starts the first day of winter 2012/2013 (often just listed as winter 2012). Winter 2013/2014 (winter 2013) would begin on December 21, 2013, at 12:11 pm EST.

In astronomy, each year in the Northern Hemisphere can be defined as beginning with the spring (vernal) equinox in March. The summer solstice occurs in June, the autumnal equinox in September, and the winter solstice in December. Astronomically speaking, in the Northern Hemisphere, the winter solstice is defined as when the Sun reaches its greatest declination (23-1/2 degrees) south of the celestial equator, around December 21. So, winter 2012 marks the time when the first day of winter begins for 2012/2013. It's the time when the Sun reaches its southernmost declination for the year 2012.

By Almanac Staff

Hello, Old Gardener, Both are correct. There are two different years referenced. For the 21st of December 2013, winter begins at 12:11 pm EST.

If December 21st is the first

By celtblood

If December 21st is the first day of Winter, why has it been referred to as Midwinter through the centuries? Is December 21st (or 20th, as it varies) not the point in time when the days are the shortest, with the next day being the time when the days begin to lengthen? And would this not, in turn, dictate that Winter proper actually begins in November? Would it not have to follow that Midsummer/Summer Solstice marks the high point of the Sun's energy and, after this, the shortening of our annual cycle of daylight hours through until the Midwinter/Winter Solstice, when the days begin to lengthen once again? If so, how could the Summer Solstice possibly be the beginning of Summer or the Winter Solstice possibly be the beginning of Winter?

The Celts divided the year into two major halves, Winter and Summer, with the cross-quarter events being the Spring Equinox and the Autumnal Equinox. The year began on November 1st, the beginning of Winter. Midwinter was genuinely the middle of Winter, ending on the Spring Equinox as Winter began to wane and the foliage bloomed. Summer officially began on May 1st, as by this time the growing season was in full swing, with the last vestiges of the Winter season behind us. Midsummer, the longest day, was the beginning of the waning cycle, as Summer began to move toward Winter. The Autumnal Equinox (generally the approximate harvest time) marked the manifestation of the seasonal changes preceeding Winter's arrival, again on November 1st. Since agriculture was the dominant industry, this reflected the agrarian/astronomical calendar cycle, which was the basis for our modern calendars.

I've addressed this before, and am still perplexed as to why anyone would insist on referring to the Winter and Summer solstices as the beginning of their respective seasons, when they clearly are not at all.

These MID-Summer and MID-Winter designations are the correct astronimical divisions of the year, as they are based on the actual effect of the solar cycle on the Earth's seasons.

I realise there are all these newer ideologies and theories on when the seasons begin and end (meteorlogical, temperature and regional variances, etc.), but the fact remains that Midsummer and Midwinter are precisely that-- the middle of these seasons, and not by any means the beginning. (Unless, of course, the Sun is wrong in his astronomical movements, and if so someone had better inform him.)

Yes, the definition of when a

By Almanac Staff

Yes, the definition of when a season begins can vary between countries, cultures, organizations, and individuals. For example, the ancient Celts considered equinoxes and solstices (called quarter days) as the midway points of the seasons. Their cross-quarter days (halfway between quarter days) were the beginning of the seasons. Astronomically speaking, however, the seasons begin at the equinoxes and solstices, which define four unique points along Earth’s orbit, in which the Northern or Southern Hemisphere tilts toward the Sun (summer), away from the Sun (winter), or is neutral--neither leaning toward nor away from the Sun (spring, autumn).

An astronomical definition does not directly take into account what is going on within Earth’s atmosphere. Other definitions focus on how the Sun’s intensity (energy) or heat affects the surface. A meteorological definition of seasons, for example, often is based on temperature. An international meteorological definition separates the year into groups of three months: March 1 is the beginning of spring; June 1 starts summer; September 1, autumn; and December 1, winter. However, days of greatest warmth and cold (on average), or length of season, can vary by region depending on their proximity to water, latitude, prevailing winds, etc.

Other seasonal definitions take into account annual responses by plants and animals. Or, define the seasons according to religious or cultural criteria.

For The Old Farmer’s Almanac, because we are a calendar of the heavens, we officially use the astronomical definition. But, we certainly agree that there is more than one way to define when the seasons begin.

There are several

By Almanac Staff

There are several interpretations as to when each season begins.
In North America, calendars commonly use the astronomical definition. It is true that various countries, cultures, religions, organizations, and individuals may use definitions other than the astronomical. Because we are an almanac that provides astronomical data, however, that’s why we use the astronomical definition. For our weather predictions, however, we start with a more meteorological definition by providing Nov-March “winter” predictions, Apr-May for spring, June-Aug for summer and Sept/Oct for fall. Hope this is helpful. --Your OFA editors

I am afraid that I must agree


I am afraid that I must agree with Jonathan. It is not simply "various countries, cultures, religions. . ." that define seasons in a variety of ways, but more so different latitudes. The so-called "astronomical" dates might seem to be more objective and authoritative, but in defining seasons as phenomena that occur uniformly across an entire hemisphere, we ignore the curvature of the earth and the tremendous variation in climate that occurs between the equator and the poles. The astronomical dates might make sense for someone living on the moon and seeing the earth as a flat disc, but for those of us living on the surface of the earth, seasons start and end at a variety of times. I think that the OFA should resist the popular compulsion to have "official" dates for the seasons and instead accept the more scientifically and historically accurate definition of seasons as annual changes in levels of sunlight, temperature, and precipitation that vary according to latitude and climate.

I am sorry but your

By Jonathan

I am sorry but your contention that the first day of spring is the equinox, the first day of summer the solstice, etc., simply is not true. The so called beginning of summer (the summer solstice around June 21st) and the end (the equinox around Sept 21 or 22) is merely the astronomical beginning and end of summer, nothing more nothing less. The meteorological beginning and end of summer is June 1st and August 31st respectively. I, and I think most people, tend to consider the meteorological time to be more accurate. Contrary to popular belief there is no official beginning and end of the seasons. No scientific or governmental body has ever formally bestowed such a designation. Again, June 21 or 22 to Sept. 21 or 22 (or Sep. 21 to Dec. 21 for Fall, etc.) are merely the astronomical beginning and end of summer it is not the "official" beginning or ending.

Great question. You are

By Almanac Staff

Great question. You are correct. The "equal" night/day usually comes a few days before the equinox. Our former astronomer, George Greenstein, had this to say: "There are two reasons. First, light rays from the Sun are bent by the Earth's atmosphere. (This is why the Sun appears squashed when it sets.) They are bent in such a way that we are actually able to see the Sun before it rises and after it sets. The second reason is that daytime begins the moment any part of the Sun is over the horizon, and it is not over until the last part of the Sun has set. If the Sun were to shrink to a starlike point and we lived in a world without air, the spring and fall equinoxes would truly have ‘equal nights.’”

I have a fairly simple

By yug

I have a fairly simple question.
Does the winter solstice in the Northern hemisphere occur at the same time as the summer solstice in the Southern hemisphere?
If there is a lag in the exact time, is that lag due to the "wobble" of the Earth on it's axis?
Enquiring minds wander...


Yes, both solstices occur at

By Miranda Mowrey

Yes, both solstices occur at the same time. The northern axis points towards the Earth, creating more exposure, summer. On the directly oppisite side of the world, the southern hemisphere is in winter, because the southern axis is pointed away from the sun, becoming less exposed to sunlight. Both are solstises because the sun is either facing the Northern or Southern hemisphere, not the equator, which results in equinox. :)

Hi All,   It is my

By Heidi Stonehill

Hi All,
It is my understanding that the winter solstice in the Northern Hemisphere and the summer solstice in the Southern Hemisphere occur at the same point in time. However, local time, due to time zones, will vary. At the December solstice, Earth reaches a spot in its orbit such that its northern axis points the farthest away from the Sun (Earth's axis is tilted 23.5 degrees away from an upright position). The timing of this event is not dependent on where you are on Earth (such as a sunrise would be). However, the local time will change. Astronomers often list these events in Universal Time (UT), which is tied in to the time at Greenwich, England (0 degree longitude). From there, we need to convert to our local time.
Sometimes, the seasons occur near midnight. Therefore, as the event gets translated into local time, it may occur on one of two days (late evening of one day or early morning of the next day). This situation is happening for the December solstice in 2011. In Universal Time, the December solstice occurs on December 22 at the 5th hour 30th minute. In Eastern Standard Time, this is 12:30 am on December 22. However, in Central Time, this is December 21 at 11:30 pm; Mountain Standard is December 21 at 10:30 pm; Pacific Standard is December 21 at 9:30 pm, etc.
Hope this helps!
