Twelve autonomous communities in Spain face official heat alerts on Friday, with temperatures expected to approach 40°C in several regions. Information from the Agencia Estatal de Meteorología (AEMET), the most severe warnings are in parts of Andalucía, including the Córdoba countryside and the areas of Morena, Condado, and the Guadalquivir Valley in Jaén.
Yellow-level warnings, indicating a potential hazard, are in effect across Aragón, Baleares, Castilla y León, Castilla-La Mancha, Cataluña, Extremadura, Madrid, Navarra, La Rioja, Comunidad Valenciana, and the Canary Islands. Daytime highs in these regions will exceed 35°C and, in some localities, may approach 40°C. AEMET’s Meteoalerta system issues warnings by region and hazard, with a forecast horizon of up to 72 hours and updates as conditions develop. Its yellow, orange, and red levels are based on thresholds that vary by phenomenon and geographic area, rather than on one nationwide temperature or rainfall cutoff.
AEMET has also issued alerts for intense rainfall and thunderstorms in Andalucía, Aragón, Castilla y León, Castilla-La Mancha, Murcia, and Comunidad Valenciana. The storms are expected to bring rapid downpours, with accumulations of 15 to 20 liters per square meter in one hour. Some could bring small hail and very strong wind gusts, risking localized disruption. The mixed pattern matches AEMET’s early-August outlook, which Diario de Ibiza described on 3 August as a forecast of “days of contrasts,” with heat in some parts of Spain and storm activity in others. On 7 August, coverage of conditions in Catalonia also highlighted the potential for intense storms and hail, showing the range of risks in the broader weather episode.
In the Canary Islands, the heat warning is limited to the eastern, southern, and western parts of Gran Canaria. A separate strong-wind alert applies to the summits of Gran Canaria and La Gomera, where gusts could reach 70 kilometers per hour. Authorities are urging residents to take precautions during periods of extreme heat and sudden storms. AEMET updates alerts as forecasts evolve, so the applicable warning may differ by location and hazard; residents can follow the agency’s official updates on heat, rainfall, thunderstorms, and wind.
In recent weeks, local governments have responded to weather-related risks in various ways. Concerns over fire hazards, for example, led several Madrid municipalities to cancel public events. A recent report described how only a portion of towns maintained their plans amid wildfire fears: Madrid towns adjust public activities due to fire risk.
Spain’s summer climate brings abrupt temperature spikes alongside episodes of heavy rain, thunderstorms, and strong winds. The combination can pose heat-related health risks and cause localized disruption, including flash flooding, damaging gusts, or hail. Residents are advised to monitor official updates, limit outdoor activity during peak heat, and stay alert to sudden changes in weather conditions. Coordination among meteorological agencies and local governments, along with public awareness, remains basic to reducing the impact of severe weather.
