Overall Iceland Travel Experience by Season

Spring (March through May)

Humidity and temperatures combine to make this season feel very cold. Highs range from 47.5°F (8.6°C) and 33.8°F (1°C) with warmer temperatures in the later months. Spring is the slowest for tourism, which makes it a good time for those looking for deals.

Summer (June through August)

The middle-year months have cold weather with high temperatures that are still jacket weather. June – August is the second busiest season for tourism in Iceland, so lodging and other accommodations may cost slightly more.

Fall (September through November)

Fall daily highs range from 53.2°F (11.8°C) and 35.4°F (1.9°C), which will feel chilly given the humidity and wind. Tourism is fairly slow during these months due to the weather, so hotels may be lower priced.

Winter (December through February)

Weather is far too cold this time of year in Iceland to be enjoyable for warm weather travelers. The average high during this season is between 37.4°F (3°C) and 33°F (0.6°C). These times of year are the busiest with tourists.
