Planning around Reykjavik's daylight is more important than temperature. I was there in June and the midnight sun meant I could hike at 11pm — disorienting but incredible. December gives you about 4 hours of daylight, which limits outdoor plans severely. The data shows mild temperatures for the latitude (rarely below -5°C thanks to the Gulf Stream), but wind chill is the real factor. Pack windproof everything, regardless of season.
