On March 1, the call began meteorological spring however the astronomical spring will take place on March 21.
They are different concepts that many people usually confuse, that is why I am going to explain the difference between these two types of spring that occur during the month of March.
It is necessary to start from the base that the four weather stations they do not coincide with the astronomical ones. In the case of meteorological spring, it depends on the climate, so its onset is variable, while astronomical spring always Starts March 21 since it coincides with the first equinox of the year.
Although the beginning of the meteorological spring usually coincides with mild temperatures like those that currently exist throughout the country, it is rash to say that such a season has entered since the predictions foresee a sharp drop in temperatures for the weekend.
For many meteorological experts you have to wait at the end of the month, to be able to determine with greater accuracy when the weather station starts. The ideal is to wait about 10 or 15 days from the beginning of the month to specify perfectly. That is why we would have to wait until March 10 to indicate with greater security and certainty when it has started meteorological spring.
As a curiosity, during this year 2016 the astronomical spring will not start on March 21 as almost always happens, it will enter at 5:30 a.m. on March 20 because 2016 is a leap year.
What is clear is that the year 2016 has started totally unpredictable in climatological and meteorological matters, since high temperatures have alternated in the month of January with colder ones traditional according to the winter season , as has happened a few weeks ago throughout Spain.
