What to expect
Daytime
Days in Iceland in December are about getting between indoor places. The cold is the story. Gloves are not a fashion choice.
A clear spell is for a short walk, then back in. Do not plan a long outdoor day as the default. Night falls early and the cold deepens with it.
Rain
December is a wetter month in Iceland. 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
