A quick, year-round overview of monthly and seasonal weather in Bilbao. Use this page to get a feel for which months and seasons match your travel style.

Bilbao weather at a glance

  • Bilbao (Basque Country, Atlantic influence) often feels driven by **rain, wind, and humidity**. Even when temperatures look mild, wet air can feel cooler on skin.
  • Summer tends to be warm rather than scorching, with many evenings turning noticeably cooler. Spring and fall can swing quickly from bright to overcast.
  • Autumn to winter (roughly Oct–Mar) is typically the wetter stretch. A waterproof jacket and shoes can be more practical than relying on an umbrella alone.
  • River walks and hillside areas can catch more wind—an extra layer for evenings can be worth it.
  • For Bilbao, planning around “wet vs dry day” often works better than a simple warm/cold label.
