The equinoxes might be expected to be in the middle of their seasons, but temperature lag (caused by the thermal latency of the ground and sea) means that seasons appear later than dates calculated from a purely astronomical perspective. The actual lag varies with region, so some cultures regard the autumnal equinox as “mid-autumn” whilst others treat it as the start of autumn .
