Nearby Community of Madrid municipalities, including Brunete and Las Rozas de Madrid, will record maximums of 34 degrees alongside morning minimums between 15 and 17 degrees. Interior northern provinces will also register elevated late-season temperatures. Logroño in La Rioja will reach 31 degrees after starting with clear skies, while nearby Calahorra will hit 32 degrees with a minimum of 13 degrees. In the Basque Country, Vitoria-Gasteiz will reach 29 degrees and a morning low of 11 degrees.

Atlantic coast conditions and approaching northern front

Northern coastal regions will experience substantially milder temperatures and increased cloud cover compared to the interior. In Asturias, Oviedo and Siero will record maximum temperatures of 24 degrees and minimums of 14 to 15 degrees, while coastal Gijon will reach 23 degrees under overcast early skies before clearing by midday. Morning mists and cloud cover will linger across Galicia and the Cantabrian strip, alongside retention cloudiness over mountain ranges. A weather front approaching during the late hours of Saturday will introduce scattered showers across northern areas. Eastern mountainous areas will also see the development of afternoon convective clouds. Subsequent forecasts indicate light rain spreading across Asturias, Leon, and La Rioja on Sunday and Monday.

Island forecasts and temperature shifts

Maximum temperatures will evolve unevenly across Spanish territory throughout Saturday. Values will decrease along the Mediterranean coastline, the northern plateau, and the Balearic and Canary archipelagos, with notable temperature drops across southeastern Spain. In contrast, daytime temperatures will increase in Galicia while remaining stable across the remaining regions. The Canary Islands will experience intervals of high clouds and suspended dust calima at altitude. AEMET forecasts potential weak showers in the interior of the western Canary Islands, particularly in Tenerife, alongside falling maximum and minimum temperatures across the archipelago.
