On Friday September 23, 2011, at 11h 5m Peninsular time, autumn begins in the northern hemisphere, according to astronomical convention. This season will last 89 days and 20 hours.
This is when the length of day and night practically coincide, and therefore, this circumstance is also called “Autumn Equinox.” This is the time of year when day length shortens faster. At latitudes of the Peninsula, the morning sun rises over a minute later than the day before and the evening becomes almost two minutes before, so that the shortening of days is especially noticeable in the evenings. In short, these days the time that the Sun is above the horizon is reduced by almost three minutes each day. Sunrise tomorrow is at 07:48 and sunset at 20:00
At the moment the maximum daytime temperature is still around 28ºc with the overnight minimum around 17ºc, a little warmer than is usual for the latter part of September.
On Sunday October 30 Daylight Saving Time will come to an end and we put the clocks back an hour to revert to standard or winter time.
To get you in the mood here is the new spot “En Brazos del Otoño” from El Corte Inglés that has just been released on major television
