EmailFall for 2012 begins in the Northern Hemisphere on September 22, 10:49 A.M. EDT. Here’s more about the first day of fall—the autumnal equinox—plus, facts, folklore, and some fantastic fall photos! (Say that five times fast!)
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. 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)

Here where I live in MA I still am hearing the peepers and cicada's. The leaves are still green. The only thing that is telling me the season is changing is it's been in the 50's at night which is nice to sleep in. The days haven't been out of the 70's for the past week.

A fall nip was in the air in the flatwoods of Fla this past weekend. What a blessing it was. Great working in the yard and pasture. Really enjoy getting our fall garden ready to plant.

The poplars around here (West Virginia) are always the first to turn, followed by maples. The poplars have been yellowing and losing leaves for about 3 weeks or better. Temps all summer have been really High, but its beginning to feel more normal now with highs in the 70's and lower 80's, lows from the upper 40's to lower 60's. And than goodness the grass growth has slowed :)

The first signs of fall I see every year is wolf spiders and wood spiders moving into my house. I love fall, but absolutely hate spiders. There's been four meet untimely deaths so far, there'll be 50 more at least before the snowflakes fall.
I love the change of seasons.
I love the change of seasons. When my grandson was 4 yrs he asked why the trees changed. Trying to explaine so a 4 yr. old could undeersta, I told him in the fall trees are puting on thier pj's, in the winter they were asleep, and in the spring when they woke up, they were green again.

The above article states that "From here on out, the temperatures begin to drop and the days start to get shorter." This is not accurate as the days start getting shorter after the summer solstice. I think what the article may have meant to say is that the days start getting shorter than the nights, i.e., there is more darkness than light in a 24 hour period.

November Night
Listen. . . .
With faint dry sound
Likes steps of passing ghosts,
The leaves, frost-crisped, break from the trees
And fall.

On around August 15th I can smell Fall in the air, the smell, the feel, it changes on that date. The squirrels are noisy now. Chirping and scurreying about storing food. Sleeping and sleepiness is of high quality as it is warm in the day and cool at night.
