A Reykjavík base with individual day trips is easier to rearrange than a chain of distant overnight bookings. Choose the trip for winter days as well as possible aurora evenings. Updated September 10, 2026 · [Published by Iceland.org]() · [Writing & review]() ## January compared with the adjacent months Reykjavík, WMO station 04030. Climate normals for 1991–2020. | Month | Average daily maximum | Average daily minimum | Monthly precipitation | | --- | --- | --- | --- | | December | 3.3°C | -1.6°C | 94.9 mm | | January | 3.2°C | -1.7°C | 87.1 mm | | February | 3.3°C | -1.9°C | 90.6 mm | Source: [WMO normals archived by NOAA (CSV)](), checked September 10, 2026. Temperatures are averages of daily highs and lows, not extremes. Precipitation is a monthly total, not the number of rainy days. This Reykjavík station does not represent every region or elevation. ## Short days and winter road plans Use the daylight for the part of the outing you most want to see. Put travel, a meal and the return journey into the same plan before adding a second waterfall. If conditions reduce the day, shorten the route rather than compressing each stop. An ice-cave booking needs a named meeting point, check-in time, equipment list and cancellation terms. Confirm the actual cave and route with the operator; a January date does not establish that a particular cave is usable. ## What to keep within reach Warm base and insulating layers, a windproof waterproof outer layer, gloves, hat and footwear with grip belong in the day bag, not just the suitcase. A headlamp helps with dark approaches; traction aids for a footpath are not glacier equipment. ## Check the conditions for your day - [IMO weather forecasts](): choose the region and forecast time. - [Road conditions]() and [SafeTravel alerts](): check the actual route and destination before departure. - [IMO aurora page](): darkness and cloud cover matter alongside activity.
