In the Canary Islands, highs will reach 34-36ºC, with overnight lows around 25ºC. Haze is expected, and heat warnings remain in effect across multiple provinces.

 

On Friday, the first signs of change arrive. Highs will start to drop across much of Spain, though the southwest will remain warm. Tropical nights will continue along the Mediterranean coast and southern regions. Nighttime temperatures will remain mild in most areas, with tropical conditions persisting in several inland zones.

 

Rain will begin in Galicia and will move across Asturias, Cantabria and the Basque Country. Afternoon showers may affect Castile and León, La Rioja, Navarra, and Aragón, with the southeastern mountains also seeing some rainfall.
