When does autumn 2023 begin?: time and day of the equinox

Summer lovers say goodbye to their favorite season. Gone are the heat waves and tropical nights, giving way to the long-awaited autumn, which usually brings rain, cooler temperatures and earlier sunsets.

Although seasonal changes are not as evident as before due to climate change, it is true that the equinoxes (equal length of day and night) and the solstices (indicating the longest day of the year in terms of light in summer and the shortest in winter) precisely mark the moment in which the Earth enters the next astronomical period.

The National Geographic Institute explains: “The beginning of autumn in the northern hemisphere is defined by the instant in which the Earth passes through the point in its orbit from which the center of the Sun crosses the celestial equator in its apparent movement towards the south. "

Spain will enter the autumn equinox today, Saturday, September 23, at 8:50 (peninsular time), giving way to a season that will last no less than 89 days and 21 hours, extending until December 22, according to the data provided by the National Astronomical Observatory.

Cold lovers will have to wait for winter, since the State Meteorological Agency (AEMET) has anticipated warm and higher temperatures than usual for this time of year. Of course, rainfall will be more frequent and abundant, especially in the northwest of the peninsula.

Regarding the schedule change, we will have to wait a few weeks, since it will take place on Sunday, October 29. By then, 3:00 will be 2:00 on the peninsula, while in the Canary Islands the clock will go forward from 2:00 to 1:00.
