Bilbao is a city full of surprises all year round. From warm summer evenings by the river to lively festivals in the old town and rainy days filled with art and pintxos – every season has its charm. But when is the best time to visit Bilbao? That depends entirely on what kind of trip you’re looking for.
Bilbao weather by season
Spring (March – May)
De lente is een heerlijke tijd om Bilbao te bezoeken. De natuur staat in bloei, het weer wordt milder en het toerisme is nog niet op z’n piek. Temperaturen liggen tussen de 13 en 20 graden, en hoewel er soms een bui valt, zijn er ook veel zonnige dagen. Perfect voor wandelen door het Guggenheim of lunchen in de zon op een terras in Casco Viejo.
Summer (June – August)
Summer in Bilbao means sunshine, culture and celebration. With average temperatures around 25°C (and sometimes higher), it’s ideal for sun lovers. That said, it can get busy – especially in August. So be sure to book your ferry in advance if you’re planning a summer trip, for example via the Portsmouth to Bilbao ferry.
Autumn (September – November)
September is a hidden gem: still warm (around 22°C), but much quieter than August. The autumn colours in the surrounding hills make this an excellent time for hikers and road trippers exploring the Basque Country. October and November are cooler and wetter, but also cosier. It’s the perfect season for visiting museums and indulging in a relaxed pintxo tour.
Winter (December – February)
Winters in Bilbao are mild compared to northern Europe, with average temperatures around 10°C. Rain is common, but the city remains lively. This is a great time to travel on a budget and avoid the crowds. Plus, Bilbao’s Christmas lights are surprisingly festive and charming.
Seasonal Highlights and Festivals
