Andorra's 2026 Summer Shatters Heat Records, Hottest Since 1950

Andorra's record-hot 2026 summer has now seen more than double the previous number of heatwave days, with 35 days through early September compared to the prior peak of 17.

The Meteorological Service reports confirm the summer's average temperature reached 21.8°C at the FEDA hydroelectric plant, a 3.4°C anomaly—the first time exceeding this level and 0.5°C warmer than the 2023 record. Stations across the country recorded 43 days above 30°C, alongside five heatwaves, topping the previous high of four in 2022 and 2023.

This marked the first season with a positive thermal anomaly over 3°C, shattering multiple climate indicators. The heatwave total climbed to 35 days when including early September, more than double the former record.

July posted the highest monthly average, followed by June and then August. The maximum temperature was 36.8°C on 7 July at Borda Vidal (873m), while the minimum stood at -1.7°C on 2 June at Solana (2,470m).

Rainfall averaged 184.7mm nationwide, with FEDA measuring 222.6mm over 32 days—typical overall but unevenly spread. June and July stayed dry, but August delivered intense storms, especially in the south. Borda Vidal saw the most precipitation at 231.8mm, Perafita the least at 137.8mm, and the heaviest single event—48.7mm total, including 26.5mm in 30 minutes—fell on 6 August at Borda Vidal.

Frost limited itself to June's first 11 days, with no snow. Strong winds on 2 July, driven by northern Atlantic high pressure, dried vegetation quickly and contributed to lightning-ignited forest fires, mostly in July plus a high-altitude incident from 24 to 27 August.

High pressure is returning, bringing clear skies, stable weather and above-normal temperatures for mid-September after this exceptionally warm summer.
