Spain is experiencing a sharp weather divide this Sunday: severe storms threaten Navarra and northern Aragón, while much of the south and east faces dangerously high temperatures. The national meteorological agency, the Agencia Estatal de Meteorología (AEMET), has issued orange alerts for extreme heat in Andalucía, Aragón, Baleares and Catalonia, with yellow warnings in Castilla La Mancha, Madrid, Murcia, Navarra and the Valencian Community. Several of these regions also have orange or yellow storm alerts. The alerts form part of AEMET’s Meteoalerta system, which issues warnings for hazards including extreme heat, heavy rain, thunderstorms and strong winds up to 72 hours ahead, updating them as conditions develop.
In Navarra and northern Aragón, forecasters expect intense showers and thunderstorms, some potentially very strong, with hail and powerful wind gusts. The risk extends to nearby areas and parts of the southeast interior, though with lower probability. A cold air mass at higher altitudes is increasing atmospheric instability, especially from midday onwards. AEMET forecast wording cited by El Cronista identified the Sistema Ibérico, the Pyrenees and the upper Ebro as areas where showers and thunderstorms could become locally strong. In Navarra, maximum temperatures in the Ribera and basic areas are forecast to exceed 39°C despite the storm risk. Aragón is also expected to see strong storms on consecutive days. The rest of the Peninsula will have mostly clear or lightly clouded skies, except in Galicia and along the Cantabrian coast, where overcast conditions will persist, and on the Alborán coast, where intervals of low cloud are expected.
Meanwhile, the heat is set to intensify across Baleares, Andalucía, the southern plateau and the eastern half of the Peninsula. Maximum temperatures are expected to exceed 35°C across large parts of the south and northeast, as well as in the Balearic Islands. In the Guadalquivir and Ebro valleys, temperatures could reach 40°C. Nights will bring little relief: tropical nights, with minimum temperatures above 20°C, are likely across much of the southeast and the islands, while some Mediterranean coastal areas will not fall below 25°C. Cooler conditions are forecast for the Cantabrian region, the western third of the country and the Canary Islands. Maximum temperatures there will fall, and trade winds may bring strong gusts.
Stable weather will dominate the archipelagos, apart from some low clouds in the northern Canary Islands. Coastal fog and mist are likely in Alborán, Galicia and Asturias, occasionally reaching inland areas in the early morning and late evening. Light haze is also expected in the Canary Islands and the southern and western parts of the Peninsula. Winds will generally be light, though the Canary Islands may see strong intervals and very strong gusts. Moderate northwesterlies are forecast for the Gulf of Cádiz, southerlies in Ampurdán and easterlies in Baleares. Elsewhere, winds will pick up in the afternoon, mainly from the west, while southern and eastern components will prevail along the eastern and northeastern coasts.
These weather extremes come as Spain continues to grapple with climate volatility. Recent months have brought disruptive events, including major wildfires that devastated parts of Ávila and Vall d’Uixó. The ongoing investigation into those incidents, detailed in this report on the causes behind Spain’s July megafires, examines the challenges posed by severe weather patterns. Authorities are urging residents and visitors in affected regions to stay alert, follow official guidance and take precautions against heat-related health risks and sudden storms. The current alerts underline the need to prepare as Spain faces another day of unpredictable, potentially hazardous weather.
Spain’s weather warning system uses a color-coded scale: orange indicates impressive risk requiring action, while yellow signals potential danger. Under Meteoalerta, alerts are organized by hazard, area and forecast period. AEMET updates information as conditions evolve, especially impressive for fast-changing thunderstorms. High temperatures and violent storms can strain emergency services and disrupt daily life, particularly in regions unaccustomed to such extremes. Spain’s diverse geography means some areas may endure oppressive heat while others face flash floods or hail damage on the same day. These patterns reflect broader climate trends affecting southern Europe, where heatwaves and severe storms are becoming more frequent and intense. Residents are advised to monitor updates from local authorities and AEMET, particularly as conditions can change rapidly.
