Spain braces for cold snap and rain ahead of All Saints' Day weekend

Spain is facing a sharp return to typical autumn weather after several days of stable conditions and mild temperatures. The State Meteorological Agency, Aemet, says the change arrives on Friday, 30 October, coinciding with Halloween and the start of the All Saints' Day holiday weekend.

Temperatures will fall markedly, especially overnight lows. In Soria and Burgos, minimums are expected around 5 and 6 degrees Celsius respectively, while Ávila, Zamora, Vitoria and Logroño could see about 7 degrees. The contrast will be stark in the south, where Seville may reach 29 degrees and Badajoz 28, while Santander stays near 17 and San Sebastián and Oviedo around 18.

“The Balearic Islands will concentrate the most intense rains of this Friday, especially in Ibiza and Formentera.”

Rain is forecast mainly in the east. The Valencian Community, the Balearic Islands and parts of Murcia are most exposed, with Valencia's coast potentially receiving more than 15 litres per square metre by Sunday, 1 November. Ibiza and Formentera are under a yellow warning for rainfall of up to 20 litres per square metre in one hour, with locally heavy showers and possible thunderstorms expected during the central hours of Friday.

Morning mist and fog banks may form in Galicia, the Cantabrian coast, Melilla, eastern Albacete and the lower Ebro. Winds will also strengthen in the Strait of Gibraltar. Meanwhile, high pressure will keep skies mostly clear over much of the peninsula, and the Canary Islands will retain some haze in the eastern half of the archipelago.

The weather shift is driven by a cold-air trough moving from the Balkans and Italy toward the western Mediterranean. Aemet warns that rain probability will increase as the hours pass, urging caution for travel and outdoor plans during the holiday period.

Looking ahead, the cold spell is expected to settle in many inland areas, particularly Castilla-La Mancha, while southern cities enjoy near-summer highs. The agency continues to monitor the situation as the weekend progresses.
