Autumn Equinox 2019 - Monday 23rd September

Take a look at some of the amusing equinox posts that have flooded Twitter. Here on the Earth's northern hemisphere, it marks the official start of fall.

Meteorologists and climatologists break the year up into four "meteorological seasons", each of which lasts for three full months and begins on the very first day of the month: September 1 for fall; December 1 for winter; March 1 for spring, and June 1 for summer. In the Southern Hemisphere, on the other hand, it is celebrated as Spring Equinox.

On social media, people are celebrating the equinox day with amusing posts. It also results in shorter days and cooler temperatures - although most of the New Jersey region will be basking in 85-degree heat when fall arrives this year, thanks to a dome of high pressure that's pushing in warm air from the south and west. For some, this translates into more time to sleep.

The point at which the length of day and night are closest to exactly 12 hours comes a few days after the Autumnal Equinox.

After this autumn equinox will come spring equinox around March 20, 2020.

The official equinox is Monday, but because of Portland's position on the Earth - just north of 45 degrees latitude, or the 45th Parallel - we won't experience an nearly perfectly even split between night and day until Wednesday, said Jim Todd, the director of space science education at the Oregon Museum of Science and Industry.
