Weather in Bilbao in December

December in Bilbao is cool outdoor weather: usable if you dress for it, not a beach brief.

In Spain, this is how Bilbao actually wears December, not how a country centroid would. Compared with August and January, December sits in the middle of Bilbao's year.

Pack for Bilbao in December, not for a brochure that was photographed in another season.

What to expect

Daytime

Cool days in Bilbao: a jumper you can take off, a shell in the bag. Walking is fine. Lingering outside without a layer is optimism.

Mornings and evenings are colder than the postcard. Pack for both, especially if you leave the built-up centre.

Rain

December is a wetter month in Bilbao. Showers are part of the deal, not a spoiled surprise.

Waterproof shoes matter more than a rain plan for a beach, especially if a beach is not why you came. Build indoor hours into the afternoon.

Evening

Evenings are cooler. A layer helps after sunset.

What to pack

  • Rain jacket

  • A layer for cooler evenings
