A polar air mass will descend over Spain just before Easter. AEMET is already talking about polar cold and significant snowfall

The key day will be Wednesday the 26th. It will be then when, at the gates of Holy Week, a mass of polar air will enter the national territory leaving cold and snow during the last week of march.

And yes, that’s what matters to us right now; but the general context is much more complicated.

But let’s talk about the cold. Starting on Wednesday, an undulation of the polar jet will push the anticyclonic ridge towards the north of the Atlantic and a very deep polar trough will descend over Europe. This will generate several storms.

In Spain, the models they don’t agree. While the European model is committed to a colder and more intense scenario; The American believes that the irruption will be limited to the north, the east and the Balearic Islands.

Be that as it may, we are talking about an isotherm of -4 degrees in the heart of the peninsula, more than significant snowfall in the Cantabrian Mountains, the Pyrenees and the Iberian system (at least in the north).

This is just what we hope for. And skepticism is more than justified: the 2025-2026 storm season has broken all records totaling (to date) 19 named systems. Furthermore, this winter has been the third wettest of the 21st century and January was the wettest month since records began. The uncertainty is, understandably and unjustifiably, greater than normal.

We must not forget that “Holy Week” is synonymous with millions of trips, thousands of outdoor activities throughout the country and hundreds of sectors that critically depend on it.

But it’s not a surprise either. According to AEMET climate dataBetween the end of March and the beginning of April, it rains some day in 70-80% of recorded years. That is to say, the distinctive thing this year will not be the rain, but the cold.

The good news. If we pay attention to the medium-term models, everything seems to indicate that the anticyclone It will recover ground around April 1 or 2. That is, we can expect the weather to be more stable in the second half of Holy Week.

Of course, the uncertainties are great and, as the old saying goes, “you should not sell the bear’s skin before hunting it.” Interesting days are coming.
