Spain is set for prolonged heat as the State Meteorological Agency, Aemet, predicts temperatures 5 to 10 degrees Celsius above late September norms. Spokesperson Rubén del Campo confirmed that northern areas may see anomalies exceeding 10 degrees Celsius.
On Thursday, 24 September 2026, highs will reach 34C in Galicia and 36C in Extremadura and Andalusia. By Saturday, the Guadalquivir valley could hit 40C, while Madrid and Seville face 34C and 38C respectively on Friday, despite isolated showers in Tenerife.
A thermal decline begins Friday in the north, reaching the western peninsula by Sunday. A weather front arriving Monday, 28 September, will likely bring rain to northern and western regions, finally returning temperatures to normal values for the season.
