Where this data comes from
These are the 1991-2020 climate normals published by AEMET, the Spanish state meteorological agency, for the Getafe observatory — the nearest official station with a complete series to Leganes today. A normal is not a forecast: it describes a thirty-year average, and any given day can depart from it widely. For tomorrow, use the forecast at the top of this page.
