It is the summer's great last heat,
It is the fall's first chill: They meet.

The Autumnal Equinox
The word equinox comes from the Latin words for "equal night." The fall and spring equinoxes are the only days of the year in which the Sun crosses the celestial equator.
From here on out, the temperatures begin to drop and the days start to get shorter than the nights. See your local Sun rise and set times and see how the days change!
Questions and Answers About Fall
Question: Why aren't there exactly 12 hours of daylight and 12 hours of darkness on the fall equinox?
Answer: On the equinoxes, the very center of the Sun sets just 12 hours after it rises. But the day begins when the upper edge of the Sun reaches the horizon (which happens a bit before the center rises), and it doesn't end until the entire Sun has set. Not only that, but the Sun is actually visible when it is below the horizon, as Earth's atmosphere refracts the Sun's rays and bends them in an arc over the horizon. According to our former astronomer, George Greenstein, "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.'"
Question: The autumn leaves seems to be hanging on longer than usual in my neck of the woods. Is this an indication of winter weather to come?
Answer: There's an old weather proverb that states, "If autumn leaves are slow to fall, prepare for a cold winter." Or perhaps you just haven't had the kind of wind or rain needed to shake the leaves loose from their branches. But look on the bright side—you get to look at the beautiful autumn foliage for a little bit longer!

Signs of Fall
In many regions of North America, the landscape silently explodes with vibrant colors of red, yellow, and orange. The leaves begin to drop off the trees, providing endless hours of jumping into leaf piles for kids and raking them back up for parents! Baseball season hits the homestretch, while football season is just warming up. Temperatures begin to drop, nights begin to get longer, and all the woodland critters are storing up for the long haul of winter.
You can track when the seasons change by recording animal behaviors and the way that the plants grow. Listen to the new sounds and observe what you hear and see.

Autumn Folklore and Verse
Autumn days come quickly, like the running of a hound on the moor. - Irish proverb
Trees snapping and cracking in the autumn indicate dry weather.
If, in the fall of the leaves in October, many of them wither on the boughs and hang there, it betokens a frosty winter and much snow.
Spring rain damps;
Autumn rain soaks.
Of autumn's wine, now drink your fill; the frost's on the pumpkin, and snow's on the hill.
- The Old Farmer's Almanac, 1993
Autumn has caught us in our summer wear. - Philip Larkin, British poet (1922-1986)

October 19th and the evenings are cool again in Los Angeles after the latest round of hot days (hopefully the last until next year). I love that golden light from the autumn sun in the late afternoon. I wish I lived in an area with lots of deciduous trees...I'd be loving the color.

What are the different factors that would make for an "Indian Summer"?

Hi, Brad, Good questions. For over 200 years, The Old Farmer's Almanac has adhered to the saying, "If All Saints' (November 1) brings out winter, St. Martin's (November 11) brings out Indian summer." Here's our page on Indian Summer and the criteria:

Here in southern Ohio, the leaves are slowly changing; others have already turned and fallen off completely! But I absolutely love fall and all that comes wit it...bonfires, Halloween, gorgeous scenery and beautiful walks through the park. Happy Fall to all! Have a great day! :)

Sunrises and sunsets are different in the fall. The air smells fresh and crisp and it's refreshing on your face. I like driving with the heat on and windows rolled down.

This is my favorite time of year! There's nothing like the smell of pumpkin bread in the oven and a pot of hot coffee brewing. Walking outside and hearing the crunching leaves underfoot. Truly the best time of the year!

I know it's autumn when I see nuts on the ground around my house. It means the squirrels are doing their winter gathering...and inadvertent scattering.

From Chicago . the leaves are starting to turn, the crickets and grasshoppers are gone from the garden, the nights are cool, the days heavenly, flannel shirt weather. The squirrels are busy burying the acorns and the smell of firewood is in the air. I wait all year long for September and October and they just fly by.

Welcome Autumn! Here in north-central California our daytime temperatures are still fairly hot (90-ish), with our nights cool 60-ish). We've had a very dry summer and need rain desperately. No real signs of autumn yet, but hopefully there will be soon.

I grew up in the midwest and love fall and the leaves changing colors!! I miss the leaves changing colors, raking the up, and jumping into the big huge pile of leaves!! Here in Phoenix we have a FEW more days of 100+ days of hot weather!!! Then it just might start to cool off into the middle to high 90's!!! Wish it would cool off more!!! Really miss the days of Fall of Wisconsin!!!!

Love this time of year! Nature is preparing to rest. The winds are blowing crisp and there's a freshness in the air! The days have become comfortable and the chilly nights make for a restful sleep. Love cooking "comfort" foods that puts a smile my family's face.

The one thing I DON'T hear that tips me off to autumn approaching, is the lack of singing birds that would wake me every morning during spring and summer. The shorter days is another hint. I never did like autumn because of the shorter days and eventually all of nature goes to sleep in a hibernation to be followed by winter and cold.

Hummingbirds left the day before Labor Day. A 14 foot Eastern Diamondback was spotted in a field nearby. It has rained nearly every day for the entire month of August near Savannah, GA

Your article says "From here on out, the temperatures begin to drop and the days start to get shorter." Actually, the days start getting shorter after the summer solstice, up until the winter solstice when they start to get longer. The autumnal equinox is when the days start to get shorter than the nights (before the equinox the days are longer than the nights).

wow i loved your writing of fall. The summer comparing to dragons breath is perfect. I felt like was on a real travel as i read along. Awesome thanks.

YAAYY just 7 weeks till we enter Virgo Pass and leave the hot dragon breath of summer xD The last month of summer 8/22 - 9/22 is the most beautiful and amazing to see. The first 2 weeks are the hottest of days as the stubborn heat from August tries desperately to hold on. Each day gets hotter and drier up the imaginary high mountain pass of Virgo - sorta like seeing the dry side of the Cascade mountains in Washington State where temps can top over 100 deg. Then about Sept 11th the midpoint is reached and there's this blast of cool air that's never been felt before from the Libra side of the mountains. The air is crisp clean and has a beautiful chill that tames the fiery dragon breath of summer. Once over the pass and below the Virgo summit in the last 2 weeks of summer, the nights get chillier and outweigh the warmth and the grasslands begin to change into an array of color. Much like the Seattle side of the Cascades where the temp can be 40 degrees cooler in a matter of a few miles, that sudden drop in temps is enough to tip the scales of fall into full swing and each day the woodlands come more alive in color as the days shorten further. The most amazing image in my mind is descending the high mountains after so much summer discomfort and suffering and seeing the crisp clear waters of Scorpio Sound with the height of fall foliage around it's pristine shores. The beautiful fall landscape around the wooded city of Libra is like the perfect city that lives harmoniously in it's own environment allowing people and nature to live together in peace and thanksgiving. I cry every year living to see this beautiful season begin and like spring, fall can be very much like heaven on Earth YAAYY!

I live in the panhandle of Idaho and about 60 to 70 miles from Canada. Which issue of the almanac should I buy? I am new to the area and am a little unsure? San Francisco is a lot further away.
