The Best Time to Visit Bilbao
I've walked the Casco Viejo in a January downpour and sipped txakoli on a July rooftop with the Guggenheim's titanium glinting below, and the difference in experience is not subtle. Bilbao sits on the Bay of Biscay, so no month is guaranteed dry, but the calendar swings hard between a gray, wet winter and a genuinely pleasant summer that locals treat as their reward for the other nine months.
Already know your dates? Build the trip itself with our Bilbao itinerary (2–7 day plans), or keep reading for the honest season-by-season breakdown.
Bilbao by season
Winter (wettest, quietest)
December–February
Good for budget city-break travelers who want the Guggenheim and pintxos crawls without lines, but expect gray skies and short daylight (sunset around 6pm).
Spring (shoulder, unsettled)
March–May
A good compromise for travelers who want greener parks and fewer crowds than summer, provided you're comfortable packing layers and a rain shell.
Summer (driest, warmest, busiest)
June–September
Best overall window for sightseeing, riverside terraces, and day trips to nearby beaches at Getxo or Plentzia; book Guggenheim tickets and hotels ahead, especially around Aste Nagusia in mid-August.
Autumn (wet again, good value)
October–November
Suits travelers prioritizing lower hotel rates and a quieter Casco Viejo over guaranteed sunshine; October still has mild, walkable days before November's rain sets in hard.
Events worth timing your trip around
- Bilbao BBK Live · July
Major international music festival at Kobetamendi hillside overlooking the city; hotel prices spike during the festival weekend.
- Aste Nagusia (Semana Grande) · August
Bilbao's biggest festival, nine days starting the Saturday after August 15, with the Marijaia mascot, free concerts, fireworks, and packed txosnas (festival bars) across the city.
- Bilbao Marathon · November
City-wide marathon and half-marathon that closes central streets for a morning; book central hotels early if racing or spectating.
- Feria de Santo Tomás · December
Traditional Basque Christmas market on December 21 with farm produce, txistorra sandwiches, and crafts filling the streets around the old town.
- Bilbao Fashion Week · March/September
Regional fashion showcase held twice yearly, drawing a design-focused crowd to city venues.
Best time to visit Bilbao: FAQ
What is the cheapest month to visit Bilbao?
January and February typically have the lowest hotel rates and flight prices, since the wet, cool winter weather keeps tourist demand down outside of Christmas week itself.
What is the hottest month in Bilbao?
August is the warmest month, with average highs around 25-26°C (77-79°F), though Bilbao rarely sees the extreme heat common in inland Spanish cities thanks to its Atlantic coastal position.
When is the rainy season in Bilbao?
Bilbao doesn't have a single dry season, but rainfall peaks in autumn (October-November) and winter (December-February), while July and August are comparatively the driest months of the year.
When are there fewer crowds in Bilbao?
Late autumn through winter (November-February) sees the fewest tourists, giving you short lines at the Guggenheim and easy tables at pintxos bars in the Casco Viejo, at the cost of frequent rain and cooler temperatures.
