What to expect

Daytime

You want a proper coat in Reykjavik in December, not a festival jacket. Wind makes the same afternoon feel sharper than the map suggests.

Outdoor time is the middle of the day. Finish plans before the light goes. Evenings are for indoors.

Rain

December is the wet side of the year in Reykjavik. Days can be heavy. Plans that cannot survive rain are the wrong plans.

This is not a reason to skip Reykjavik if you like the place. It is a reason to pack for weather and to stop treating every grey hour as a failed holiday.

Evening

Evenings are cooler. A layer helps after sunset.

What to pack

  • Rain jacket

  • A layer for cooler evenings
