Bilbao’s weather is mild year-round with wet winters and warm, partly cloudy summers. The live forecast above shows today’s conditions, typical of a city sheltered by hills near the Bay of Biscay.
What weather can you expect in Bilbao through the year?
Bilbao has an oceanic climate, similar to the UK but warmer and more humid. Winters (December to February) are cool and rainy, with average highs around 13°C and frequent drizzle. Summers (June to September) are comfortably warm, often reaching 25°C, though sea breezes keep it pleasant. Spring and autumn are changeable, with dry spells interrupted by Atlantic fronts. Unlike inland Spain, Bilbao rarely sees extreme heat or cold.
Does Bilbao have a defined rainy season?
Yes – the wettest period is from October to January, when Atlantic depressions bring persistent rain. However, showers can occur in any month, so packing a waterproof is sensible even in summer.
When is the best time to visit Bilbao for good weather?
Many visitors choose June through September, when temperatures are warmest and rainfall lowest. July and August are peak season but not excessively hot, making it ideal for exploring the city and nearby coast.
Does it ever snow in Bilbao?
Snow is rare in the city centre because of its low altitude and the moderating effect of the Bay of Biscay. A light dusting may occur once every few years, usually in January or February, but it rarely settles.
