Which regions are under Spain's heat and storm alerts today?
According to AEMET, eight autonomous communities carry active warnings. Heat alerts cover Cádiz, Granada and Huelva; Albacete, Ciudad Real, Cuenca and Toledo; Lleida and Tarragona; Badajoz and Cáceres; and Madrid's Sierra, metropolitan, Henares and southern zones.
Córdoba, Jaén and Sevilla reach orange alert level for extreme heat. Rain and thunderstorm warnings apply to Granada and Jaén, Teruel, northwest Murcia and Castellón, with Albacete on storm-only alert.
How hot will it get in Madrid and Andalusia?
Madrid starts clear and climbs to around 35–37°C, putting the capital under yellow aviso calor from early afternoon. Andalusia bears the brunt: Écija is forecast to reach 41°C, Córdoba 40°C, and Sevilla and Loja about 39°C. Many other southern towns will sit near 38°C by late afternoon.
Castilla-La Mancha mirrors the pattern. Toledo may hit 38°C, while valleys along the Tajo and Guadiana could reach 38°C with storms in the southeast later in the day.
Where will storms and strong winds hit on Wednesday?
Andalucía and Castilla-La Mancha face yellow storm warnings, especially Albacete, Granada and Jaén. AEMET warns of locally heavy showers, hail and very strong gusts in eastern Andalusia and southeastern Castilla-La Mancha.
Clouds will build over eastern interiors by afternoon, with possible storms in the Iberian system and southeastern sierras. In Canarias, trade winds may bring strong intervals and very powerful gusts on exposed slopes, while the Strait and Alborán coast see moderate levante winds with intense gusts.
What should residents expect beyond the peak heat?
Most of peninsular Spain and the Balearics stay largely sunny under high pressure. Exceptions include low clouds and isolated drizzle around the Strait, Ceuta and Melilla. Northern Spain clears after morning fog banks.
Night offers little relief: tropical nights above 20°C are expected on Mediterranean coasts, northeastern depressions and low-lying Andalusian areas. Calima haze may affect Alborán, the southeast, Balearics and eastern Canaries. Stay hydrated, limit midday exposure and monitor official updates as conditions can shift quickly when storms develop.
