My take: I've tracked weather and crowd data for Bilbao across every month since 2020. The numbers below come from Open-Meteo historical averages (1990-2024), flight-price trackers from Aviasales, and my own trip notes. If a month looks "good" on paper but I'd personally skip it, I say so.

Spain · Real weather data · Updated April 2026

Best months: October, July, August — comfortable temperatures, lower rainfall, good value.

I went to Bilbao in July 2023 and was shocked by the intense heat; it felt much hotter than the coastal summers I'd experienced elsewhere. Best months: July (avg 26°C, 42mm rain, 70% sunny days), August (avg 28°C, 35mm rain), October (avg 18°C, 60mm rain). Be warned: weekend Guggenheim queues start before 9 AM, often taking 45+ minutes for a 30-minute visit—skip Sundays if possible.
