Spring does not always arrive on 21, nor on a sunny day. This year, the astronomical phenomenon that marks the beginning of the station will be on Thursday at 10.02. Then, the spring equinox will occur: at that time the earth crosses a point of its orbit in which the center of the sun crosses the celestial ecuador in its apparent movement north. The fact will coincide with the arrival at the peninsula of Martin, The fourth storm in the last 12 daysWhich, in addition to the rains, will bring gusts of wind up to 110 kilometers per hour.
In the 21st century, the beginning of spring may vary between 19 and 21 March, according to a report by the National Astronomical Observatory collected by Servimedia. The variation depends on the relationship between the Gregorian calendar and the rotation of the earth around the sun. The planet has already recorded the most backward spring of the century in 2003, but not the most advanced, which will be in 2096. During the 92 days and 18 hours that will last the season this year, the days in Spain will be extended to a rhythm of almost three minutes a day until the arrival of the summer, on June 21. Every morning, the dawn will be advanced more than a minute; Every afternoon, more than a minute will be put later.
This Thursday, the day and night will have practically the same duration. The same will happen in the southern hemisphere, where autumn begins. This is because the axis of the earth is perpendicular to its orbit around the sun. Hence the name given to the phenomenon: the Latin equinox is Aequinotiumwhich means “equal night”.
Given the illusion of the hottest temperatures that spring brings, the peninsula is preparing for the arrival of Borrasca Martin. One day from the departure of LaurenceThe new storm, from the Atlantic, will notice 16 provinces. In the communities such as Andalusia, where strong rains produced an important flood of the Guadalquivir river and floods in Córdoba and Malaga, president of the Junta de Andalucía, Juanma Moreno, asked for “coordination and prudence” in a publication in his story X.
We are very aware of a new storm that will leave strong rains again from tomorrow, such as the @Aemet_esp.
This morning we analyzed the situation during the meeting of the emergency plan in front of the floods.

Despite the bad weather that punishes Spain weeks ago, If the transformation of the night sky can be observed. In the first days of spring, the characteristics of winter like Orion, the mayor and twins will still be visible. To the extent that the Earth advances on its orbit in the direction of the summer solstice, the spring constellations Leo, Virgin and Boyero will be made with the sky.
The same goes for the presence of the planets. Mars and Jupiter will continue present after the first occasions of the station. However, Jupiter will disappear in early June, when Mercury appears. During the early morning, spring will open its orphaned path of the planets, until the end of this month Venus. In April, Saturn and Mercury will do so, which will disappear quickly, at the end of May.
Eclipse and time change
While the Parliament and the European Commission have pronounced in favor of the elimination of time changesSpring also brings a summer program. As with each last Sunday of March, at 2.00 in the morning you will have to advance the watches at 3.00. Therefore, the 30th will lose an hour and the summer program will begin. The day before, however, something unusual will happen: a partial solar eclipse can be seen throughout Spain.
This eclipse, which will happen at noon, is the first of an unprecedented astronomical calendar in Spain. In August 2026 and 2027 two total eclipses will be seen. In January 2028, there will also be an eclipse.
