What is the autumn equinox?
According to the UNAM, an equinox, whether it be spring or autumn, occurs “when the apparent position of the Sun crosses the celestial equator.” This phenomenon causes the Sun's rays to “strike almost perpendicularly on the Earth's surface, causing day and night to have a very similar duration.”
The word “equinox” means “equal night” and comes from the Latin aequinoctium.

This season is characterized by clear skies, cool nights, and nights that get “colder as we approach December.”
