Reykjavik is milder than its latitude suggests
Despite sitting further north than most of Alaska, Reykjavik's coastal position and the influence of the Gulf Stream keep its winters considerably milder than cities at similar latitudes inland — genuinely closer to a raw, windy version of a place like Seattle than the deep-freeze many visitors picture. Our general Iceland weather guide covers the country broadly; this page focuses specifically on the capital.
Reykjavik by month
| Month | Avg. high / low | Daylight | Notes |
|---|---|---|---|
| January | 3°C / -2°C (37°F / 28°F) | ~4–5.5 hrs | Coldest month, but rarely extreme; frequent wind |
| March | 5°C / 0°C (41°F / 32°F) | ~10–12.5 hrs | Daylight lengthening fast; still winter driving conditions |
| May | 10°C / 4°C (50°F / 39°F) | ~16.5–19 hrs | Genuinely pleasant, one of the better shoulder months |
| July | 15°C / 10°C (59°F / 50°F) | ~19–21 hrs | Warmest month, still cool by most summer standards |
| September | 11°C / 6°C (52°F / 43°F) | ~12–15 hrs | Nights dark enough for aurora by late in the month |
| November | 5°C / 1°C (41°F / 34°F) | ~6–8 hrs | Days shortening quickly; wetter than midwinter |
Rain and wind matter more than the temperature number
Reykjavik sees rain or drizzle on a large share of days across the year, but usually as light, passing showers rather than prolonged downpours — the kind of weather where a proper rain shell and a positive attitude do more than an umbrella, which the city's frequent wind will happily turn inside out. Wind, more than cold, is the thing that catches visitors off guard; see our general weather guide for packing advice that applies here just as much as anywhere else in Iceland.
What this means for planning a city visit
There's no bad month to explore Reykjavik itself
Unlike road trips or highland hikes, a Reykjavik city visit isn't especially weather-dependent — museums, restaurants, geothermal pools and most shops are all indoor or short-walk activities. Winter's short daylight hours are the main practical constraint, worth factoring into how you plan each day's outdoor time versus indoor time.
Where to check current conditions
For up-to-the-day forecasts once you're actually planning specific outings, the Icelandic Met Office (vedur.is) is more current and more locally accurate than most international weather apps — see our aurora forecast guide for how to read their tools if the northern lights are part of your Reykjavik plans.
