Bilbao in August
Great time to visit
August peaks with Aste Nagusia festival turning the city upside down for a week. Great weather but maximum crowds and maximum prices - only visit if you love festivals or can avoid the main celebration week.
Weather
August continues hot summer weather with temperatures of 24-27°C and minimal rainfall. Expect 8+ hours of daily sunshine with just 4-5 rainy days, often late-afternoon thunderstorms that cool things down nicely.

All Months
May through October offers the best weather, but each season brings different energy. **Summer** (July-August) sees temperatures around 25°C with occasional rain showers. The city empties as locals head to the coast, making it perfect for museum visits but quieter for nightlife.
**Late spring** (May-June) might be ideal. Temperatures hit 20-22°C, rain decreases, and locals are out in full force. Hotel prices stay reasonable before summer peaks.
**Early fall** (September-October) brings comfortable temperatures and the return of cultural programming. The Bilbao International Festival of Documentary and Short Films happens in November.
**Winter** gets wet and gray, with temperatures around 10-15°C. But this is when the city feels most authentic — locals pack into pintxos bars by 7 PM, and you'll have museums mostly to yourself. Plus, hotel rates drop significantly.
Avoid **August 15-31** if you want the full Bilbao experience. Many restaurants close for vacation, and the city loses its local energy. The weather's nice, but you'll miss the point of visiting.
