Andorra Issues Yellow Alert for Heatwave Up to 35°C Through Sunday

Andorra's meteorological service has extended its yellow alert for high temperatures amid an exceptional late-season heatwave that could break September records, with peaks up to 35°C forecast in the warmest valleys through Saturday.

The alert, initially issued Thursday noon and nationwide until Sunday, now accounts for Thursday's record highs: 34.1°C in La Comella, 33.7°C at Borda Vidal, 33.3°C at Roc de Sant Pere, and 30.2°C at FEDA's Engolasters station. Central and southern areas saw heatwave-level values yesterday, driven by persistent Iberian high pressure and a warm air mass.

Friday and Saturday will maintain sunny conditions with highs reaching 35°C in lower valleys like Andorra la Vella, 30°C at 1,500 meters, and around 18-19°C at Pas de la Casa. Minimums are expected near 15°C in central valleys, 12°C mid-mountain, and 14°C higher up. Suspended dust from an African air mass may appear Friday, with high clouds possible Saturday.

Relief begins Sunday as a less warm air mass reduces temperatures to yellow alert levels, persisting until Monday, though full normalization is not expected until Wednesday. The alert remains in effect nationwide through Sunday.

Protecció Civil recommends limiting outdoor activity and exercise during peak heat, staying hydrated, wearing light clothing, protecting the head, and seeking air-conditioned spaces. At home, close sun-exposed windows and shutters during the day, open them at night, use cooling systems, stay in cooler areas, and choose light meals. For infants, ensure frequent hydration, minimal sun exposure, light clothing, and head protection. Check daily on elderly or ill individuals living alone, and provide pets with shade and water. Officials stress caution during this prolonged event.
