What is the average temperature in Andorra by month?
In the capital, Andorra la Vella (1,023 m), average highs range from 9°C in January to 27°C in July. At higher ski resorts (2,000 m+), winter averages sit around -2°C to 2°C, while summer lifts rarely exceed 15°C. Spring and autumn are cooler and wetter, with temperatures often sitting between 6°C and 16°C – ideal for valley walks but less reliable for sunbathing.
How does altitude affect the weather in Andorra?
Andorra is one of Europe’s most mountainous microstates. For every 300 m gained, expect a drop of roughly 2°C. This means weather in Andorra ski resorts (e.g. Grandvalira, Vallnord) can be 8–10°C colder than in the capital. Snow cover typically lasts from December to early April above 1,800 m, while valleys see rain rather than snow in winter. The Andorra weather forecast 30 days is rarely reliable for high peaks, so check a weather in Andorra 14 days outlook before booking trips.
