First day of fall

Welcome to Fall!

The Autumnal Equinox -- as it's officially called -- is the exact moment when the sun is over the Equator -- which is at 9:30 a.m. ET Tuesday, creating near-equal day and night.

A cool start

Unlike last year, we're off to a cool start to fall in Atlanta. The normal high is 80 degrees, while the normal low is 63.

This year, the low was in the low 50's Tuesday morning, with the high will only be 74 degrees.

The high was 91 degrees last year on the first day of fall!

Loosing daylight

In addition to cooler temperatures, fall is also known for our continued loss of daylight, a process the began at the start of summer in June.

Sunset is at 7:33 p.m. tonight with about 12 hours, 7 min. of daylight. By Nov. 1, sunset will be at 5:44 p.m. (after Daylight Saving Time ends) with about 10 hours, 47 min. of daylight.

The seasons

The Earth's axis is tilted, which means that as Earth moves around the sun, for part of the year the Northern Hemisphere is tilted toward the sun (summer), while we're tilted away from the sun in the winter. Twice each year, we're not tilted in either direction, which are the equinoxes (spring and winter).
