Autumnal equinox arrives in Northern Hemisphere

Stuart Clark 15 September, 2025

Summer comes to a close for us in the Northern Hemisphere this week on 22 September 2025, as we enter the autumn. The moment is marked by the autumnal equinox, which is the moment when the sun crosses the celestial equator, moving south, and then, gradually, the days become shorter than the nights. The exact moment this happens is 19:19 BST (British Summer Time) on 22 September and it is caused by the movement of Earth along its orbit, gradually moving the Northern Hemisphere away from the sun.

The name equinox comes from the Latin aequus, meaning equal and nox, meaning night. So, it is said that the equinox is when day and night are the same length, which would be true if Earth had no atmosphere.
