Where this data comes from

These are the 1991-2020 climate normals published by AEMET, the Spanish state meteorological agency, for the Sevilla Aeropuerto observatory — the nearest official station with a complete series to Dos Hermanas today. One caveat: no station with a complete normal series sits inside Dos Hermanas today, and the nearest one that does is 15.3 km away at 34 m, so these figures describe its surroundings rather than the city itself. 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.
