The Official First Day of Fall

Writterdeb's Weather Update:


Though Starbucks has been selling its famous pumpkin spice lattes for weeks, fall wasn’t here — until now.

The fall equinox, sometimes called the September equinox, is on Saturday, Sept. 22 this year  and will mark the first day of fall for the Northern Hemisphere.

Just in time for the foliage to appear, here’s everything you need to know about the first day of fall, what happens when the season changes and what kind of weather we can expect this year.

When is the first day of fall?

The first day of fall is on Saturday, Sept. 22. Beginning at 9:54 p.m. (E.S.T.), it will officially               be autumn for the Northern Hemisphere, according to the U.S. Naval Observatory.

Sept. 22 is the first day of fall because it is when the autumnal equinox — the moment when “a planet’s subsolar point passes through its equator,” according to National Geographic — takes place. In layman’s terms, the autumnal equinox is when the Earth’s equator passes through the sun.

Since it is opposite on either side of the equator, the autumnal equinox faces the Northern Hemisphere away from the sun, while the Southern Hemisphere faces towards it.

For the Southern Hemisphere, the September equinox is actually the vernal or spring equinox. In the Northern Hemisphere, the vernal equinox takes place on March 20, 2018, when it finally becomes autumn in the Southern Hemisphere — which is why the Northern and Southern Hemispheres experience virtually opposite seasons.

What happens during the fall equinox?

The most notable and immediate change with the equinox is that the day and night have equal length, according to the National Oceanic and Atmospheric Association (NOAA). The word “equinox” means “equal night” in Latin'

And, in the north, the Aurora Borealis, or Northern Lights, are in their peak moment of view after the autumnal equinox, according to History.com.

Cultures around the world celebrate the fall equinox in different ways. In the United States, many Native American tribes use the equinox as an indicator for the harvest season, according to Indian Country Today. Outside of the United States, the annual Chinese Harvest Moon festival also coincides with the autumnal equinox.

Certain religious holidays, such as the Jewish celebration of Rosh Hashanah, also coincide with the equinox.

What will the weather be like this fall?

If you felt like the summer’s sweltering temperatures would never end, you’re not alone: this was the fourth-hottest summer on record in the United States, according to the NOAA — tying with the summer of 1934. The month of June was the fifth-warmest on record for the entire world, too.

So I guess we can now officially say, Happy Fall Y'all.  Hope it is long enough before winter hits that we can all enjoy the break between hot then cold.

Todays update from the Blue Ridge mountains are saying now fall colors here will be coming in late...obviously, due to the extension of summer temps. I just saw a few min ago we will hit 90 degrees on Thursday. Yikes...we leave for Arizona next weekend, so hopefully it will be cooler upon our return.
