The autumn equinox, marking astronomical fall, will occur on September 22 at 2:19 p.m.
WASHINGTON — While the temperatures may not reflect it, astronomical fall is quickly approaching.
Meteorological fall began 13 days ago, on Sept. 1. Meteorological fall always begins on the first of September and ends on November 30.
The autumn equinox marks the first day of astronomical fall. This year, the equinox arrives on Monday, Sept. 22, at 2:19 p.m.
This date can vary every year by one or two days around Sept. 21 through Sept. 23. And it marks the day the sun’s rays are directly over the Earth’s equator.
Meteorological seasons are defined by the weather. They break down the year into three-month seasons based on annual temperature cycles. By that calendar, spring starts on March 1, summer begins on June 1, fall begins on Sept. 1, and winter begins on Dec. 1.
Astronomical seasons are based on how the Earth moves around the sun.
The solstices mark the times during the year when the Earth is at its most extreme tilt toward or away from the sun.
The summer and winter solstices occur when the sun’s path is farthest north or south of the Earth’s equator. The summer solstice – or first day of astronomical summer – occurs on or about June 21 in the Northern Hemisphere. That’s also the first day of winter in the Southern Hemisphere.
According to the Farmers’ Almanac, fall 2025 will be a meteorological mix-up, with early snow possible in parts of the North and unseasonably warm conditions lingering in much of the South and West.
