Weather in Bilbao

Best time to visit

Undoubtedly the best time of year to visit Bilbao is in August when the weather is hot and dry and the biggest festival of the year, Aste Nagusia, dominates the month. Several other festivals happen at this time of year too and it is the best season to hit the beach. That said, winters are rarely too cold in Bilbao, usually dropping to 5°C (41°F) at the lowest. Museums and sites of interest are open all year round and early spring is a choice time to visit if you don’t like things too hot.
