Leaves and life change at the Fall Equinox

As nights get colder, leaves are turning gold, scarlet and copper. It’s the Fall or September Equinox. And, drum roll, it is happening Sept 23, 2023 at 2:50 a.m. EDT in the Northern Hemisphere.

The exact time is when the sun crosses the equator when going south from the north. The occasion is also known as the astronomical date for fall.

Vacationers wanting to head to the Southern Hemisphere know that the season will be warm because fall there doesn’t start until in March.

Meteorologists define fall using the average temperature change which happens the first day of the equinox month so their fall definition in the Northern Hemisphere began Sept. 1.

It’s likely you don’t need to be told that the days are getting shorter and night are longer. We seem to want to stay in bed longer and maybe change our schedules to use more daylight.

But at the Equinox they are equal before they continue in their short and long time spans.

Thus, the shortest day of the year is at the winter solstice. For more information and fun facts visit The Old Farmer’s Almanac.

 

Harvest Moon says fall is here

You might not have heard of the Sturgeon Moon in August or the Buck Moon in July but chances are you’ve heard of the Harvest Moon that is appearing overhead now in September.

It’s more than just a popular song.

Harvest Moon is the name some cultures, native tribes and farmers have given to the full moon that usually appears mid to late September because it rises when the sun goes down thus giving famers more light to get the crops in.

In the Northern Hemisphere, the Harvest Moon is the full moon closest to the September autumnal equinox. In 2021 that comes Sept. 22 when day and night are about equal in length. (It comes in March in the Southern Hemisphere)

You probably noticed that large golden orb already appearing above the horizon. It will be fullest and brightest Sept. 20, about 6:45 p.m. CDT. but will also appear full the following day.

If listening to TV weather reports, you are likely to hear meteorologists referencing the date as the beginning of autumnal fall but adding that meteorological fall began about 3 weeks before the September equinox on Sept. 1.

Autumnal fall ends at  the December Solstice, when astronomical winter begins. but for meteorologists the fall season ends Nov. 30.
