Central Asturias, the zone of Oviedo, Siero, Langreo and Mieres, lives with few warnings: heavy rain spread through the year and storms that cluster in June.
That single red day was for heat, on 15 August 2025: in Asturias red starts at 40 °C, and reaching it is extraordinary.

How this was made
Everything comes from the archive of official AEMET warnings that Climaviso has kept since June 2018: each day counts once, at the highest level the zone had. A warning is a forecast, not damage or a measurement, and it's issued for the whole zone, not your street. We don't cover measured temperatures or rainfall: only when, and why, a warning was issued.
