Andorra's First Summer Day of 2026 Turns to Heavy Rain and Snow by Sunday

Andorra is experiencing its first summer-like day of 2026, with temperatures exceeding 25°C at lower-altitude stations including Borda Vidal (25.4°C) and Margineda (25.6°C), according to recent observations. Stable anticyclonic conditions will continue through Saturday midday, delivering warm, sunny weather with highs above 20°C in Andorra la Vella.

However, a sharp shift looms as an Atlantic front approaches. Cloud cover and dust in suspension will increase from Saturday afternoon, leading to initial precipitation overnight into Sunday. Widespread, abundant rain is forecast nationwide on Sunday, intensifying in the afternoon, accompanied by a marked temperature drop of more than 10°C from current levels. Maximums will struggle to surpass 12°C in the capital, 8°C at 1,500m, and 2°C at high passes like Envalira.

The cold will peak Monday, with intense frigid conditions across the Principat. Minimums could reach -9°C at Envalira, 1°C at 1,500m, and 2°C in Andorra la Vella. Snow levels will hold above 2,500m until Sunday midday but may descend to 1,200m in the northern extremes by afternoon and evening, persisting weakly through Monday afternoon, the Servei Meteorològic d’Andorra reports.

High pressure will return Tuesday, stabilizing conditions for the following week. Residents should brace for the abrupt change from mild warmth to wet, wintry weather.
