MYRTLE BEACH, SC (WMBF) - Today is the first day of Autumn but why is the first day of Fall different each year?

At the moment of this year's Autumnal Equinox, it should theoretically disappear completely from view, and yet its disk will still be hovering just above the horizon. Not until nearly 51 hours later will the last speck of the sun's upper limb finally drop ...

The equinox has no relationship to Houston’s weather, and the city’s climate afterwards isn’t guaranteed to bring cooler or warmer temperatures.

Our days will soon be getting cooler, shorter and darker earlier as clocks fall back an hour for Daylight Saving Time.

If you get up early enough, you can experience an equinox sunrise. The autumnal equinox heralds the arrival of fall in the northern hemisphere.

Today marks the autumnal equinox, or the first day of astronomical fall. Have you ever wondered why it occurs on a different day and at a different time each year? Let’s break it down! Let’s start with the basics.

The first day of fall is on Sunday, Sept. 22, 2024, in the Northern Hemisphere. These are just two different ways to carve up the year. Meteorological seasons are defined by the weather. They break down the year into three-month seasons based on annual temperature cycles.

People participate in rituals during a fall equinox celebration on an embankment of the Neris River near King Mindaugas' Bridge in Vilnius, Lithuania, in 2019. Twice a year, the sun doesn’t play favorites.
