Bilbao in September
Great time to visit
September might be Bilbao's perfect month with excellent weather, manageable crowds, and everything still open from summer. The sweet spot between peak season chaos and autumn weather decline.
Weather
September delivers ideal conditions with temperatures cooling to 22-25°C and very manageable rainfall. You'll still get 7-8 hours of sunshine daily with only 6-7 rainy days. The oppressive summer humidity breaks.

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.
