Pull out your favorite cozy clothes because it’s almost time for sweater weather! The autumn equinox is the official start of fall, when the weather starts cooling down, the leaves begin to change, and nights slowly get longer than days. For many people, it feels like a natural pause in the year. It’s a shift from summer’s energy into the cozier, slower vibe of autumn.
What is an equinox?
An equinox is the point in the year when the Earth’s axis isn’t tilted toward or away from the Sun, which makes day and night almost the same length. The word itself comes from Latin, meaning “equal night,” and it’s a fitting description. On these days, outside of the polar regions, the Sun is above the horizon for about as long as it’s below it, creating a natural balance between light and dark as the seasons shift.
When is the fall equinox this year?
The fall equinox in 2025 will take place on Monday, September 22. On this day, daylight and nighttime hours are almost perfectly balanced, signaling the official start of autumn in the Northern Hemisphere. From this point forward, the days will gradually get shorter and the nights longer as we move toward winter, bringing with it cooler weather, colorful leaves, and the cozy feel of the fall season. So take time to celebrate the balance of day and night as the season shifts and nature prepares for autumn’s cozy embrace!
