Weather forecasts for September 25, 2026, indicate varied conditions across several regions in Spain, characterized by the ‘veranillo de San Miguel’ (San Miguel summer). This phenomenon brings dry, sunny conditions and elevated temperatures typical of late summer. In the southern region of Andalucía, heat remains intense. Temperatures in the Guadalquivir valley and parts of Seville, Córdoba, and Jaén are expected to reach between 38 and 39 degrees Celsius, prompting heat warnings. Zafra is also seeing high temperatures, with peaks reaching 37 degrees Celsius under warm and cloudy skies. Other regions show significant thermal variation. In Castilla y León, plateau areas are expected to reach 29 to 30 degrees Celsius, though a significant thermal drop is anticipated for Sunday with the arrival of an Atlantic front. Tomelloso and Talavera de la Reina are seeing highs of 35 and 36 degrees Celsius, respectively, before a potential shift toward rainier weather. In the Canary Islands, Gran Canaria is under a yellow alert for high temperatures, with southern areas potentially exceeding 34 or 35 degrees Celsius. This alert is accompanied by ‘calima’ (suspended dust) and strong winds. Meanwhile, northern and coastal regions such as Bilbao, Vilanova de Arousa, and Ferrol report milder conditions, with temperatures ranging from 25 to 27 degrees Celsius. Bilbao is specifically noted for experiencing temperatures above the September average, while La Rioja enjoys clear skies favorable for agriculture. Other locations like Sineu and València expect mostly clear skies and stable temperatures.
