ClimavisoSpain in May: where the bad weather is, and where it isn't
Averages for 2019–2025, from official warnings. Updated 26 October 2026.
May is when afternoon storms begin, and with them inland warnings: the Pyrenees and the Ebro valley open the season. The Canaries, meanwhile, barely notice.

How to read these numbers
A zone-day is one warning zone with a warning on one day: Spain has 182 zones, so ten zones warned on the same day make ten. Each zone has its own thresholds, so a warning doesn't mean the same everywhere. And a warning is a forecast, not damage or a measurement: we count when and where warnings were issued, not how much rain fell or how hot it got.
