Iceland Weather & Climate: Monthly Averages

Monthly climate averages for Iceland, temperatures, rainfall and the best time to visit.

Climate overview of Iceland

When thinking about Iceland’s climate, you might imagine extreme cold. However, contrary to what the name suggests, Iceland is often warmer than expected. The country is warmed by the Gulf Stream and has a maritime climate, transitioning to a tundra climate despite its high latitude just outside the Arctic Circle.

Winter Conditions

During the winter months, average temperatures in Iceland range between -3°C (27°F) and 6°C (43°F). Due to its proximity to the North Pole, daylight hours are limited in the coldest months. Most travelers do not venture beyond the southwest in winter, but with a 4×4 vehicle, it is still possible to explore the island.

Weather and Snowfall

Iceland is known for its rough and unpredictable weather, which complements its rugged landscape. Frequent depressions bring harsh conditions, including rain (or snow) combined with strong winds. From December to April, snowfall is common across the country.

Summer and Best Travel Period

In summer (June, July, and August), Iceland experiences average temperatures between 10°C (50°F) and 15°C (59°F). This is the best time to visit due to the highest chance of clear and sunny days. If you want to avoid the summer crowds, visiting in May, September, or October is also an option, though some inland hotels may already be closed or not yet open for the season.
