The spring equinox begins today at 8:24 pm, according to the so-called coordinated universal time, for the two hemispheres of the planet, north and south. It will last 92 days and 18 hours. It will end on June 21, giving way to the summer solstice. Scientifically, the beginning of spring in the northern hemisphere is defined by the time when the Earth passes the point in its orbit from which the center of the sun crosses the celestial equator in its apparent movement towards the north. On the day when this happens, the length of day and night practically coincide. This circumstance is also called the spring equinox. While spring begins in the northern hemisphere, autumn begins in the southern hemisphere, according to Spain’s National Astronomical Observatory.

The weather forecast for this season, as with autumn and winter, is of interest to all of society, but above all to the agricultural sector. The State Meteorological Agency (Aemet) predicts higher temperatures than normal for this spring and, mainly, rains, after a winter that prolonged the drought, the lack of water for fields and reservoirs. A warm winter is behind us, the tenth warmest since the beginning of the time series in 1961 and the fifth warmest of the 21st century. However, the Aemet forecast says that this spring the rains could stay around their normal average; yes, more abundant on the Atlantic side of the peninsula than in the Mediterranean. Andalusia will register in this first week of spring maximum temperatures above 25 degrees in some provinces, with dry and stable weather due to the Atlantic anticyclone that is located over the Azores and that causes a blockade of storms, as explained to Europa Press by delegate Aemet in Andalusia, Ceuta and Melilla, Juan de Dios del Pino, who detailed that during the first part of the week (Monday, Tuesday and Wednesday) there will be low clouds in the morning, while from Thursday there will be high clouds throughout the weekend. In addition, del Pino stated that precipitation is not expected in any Andalusian province. Sunday will be the hottest day of the week, with Malaga in the lead with 31 degrees, followed by Seville and Granada, with 29 degrees respectively; Córdoba, with 28; Huelva, with 27; Almeria and Jaén, with 25 eachand, finally, Cádiz, with 22 degrees.

Among the curiosities of this season, it has been observed so far this century that the beginning of spring can occur, at most, on three different calendar dates (March 19, 20 and 21), with its earliest beginning being in 2096 and the most recent in 2003. The variations from one year to the next are due to the way in which the sequence of years according to the calendar adjusts (some are leap years, others are not) with the duration of each Earth orbit around the Sun. Early spring is the time of year when day length increases most rapidly. At the peninsula’s latitudes, the sun rises in the morning more than a minute earlier than the day before and sets more than a minute later in the afternoon. As a result, in early spring, the time the sun is above the horizon increases by almost three minutes each day.

Weather changes and eclipses

During the spring of 2023, there will be two eclipses, one of the sun and one of the moon. The solar eclipse will take place on April 20, will be of mixed type and will be seen in Southeast Asia and Oceania. The lunar eclipse will take place on May 5, it will be of the penumbral type, and can be seen in Africa, Asia and Oceania. Other phenomena of astronomical interest during the spring of 2023 are the Lyrid meteor showers, whose maximum is expected around April 23, and the Eta Aquarids, with a maximum around May 6. The season’s full moons will occur on April 6, May 5, and June 4.

Although both the European Parliament and the Commission have decided in favor of eliminating time changes in the future, there is still no final decision on the matter. Therefore, during the year 2023, the traditional time change that occurs on the last Sunday in March will continue to be in effect. On that day, March 26, at 2 am Peninsular time, clocks will be moved forward one hour to 3. In the Canary Islands, 1 am will become 2 am.
