Water Temperature in Iceland: General Trends and Swimming Opportunities

Iceland, located in the North Atlantic, is known for its dramatic landscapes of volcanoes, glaciers, and geothermal hot springs, but its sea temperatures are cold, especially for those unaccustomed to such conditions. The average sea temperature around Iceland ranges from 3°C (37°F) in the winter to about 10°C (50°F) in the summer. While these temperatures make outdoor swimming in the open ocean challenging, they are ideal for those seeking a more adventurous swimming experience with proper gear, such as wetsuits.

Despite the chilly waters, Iceland offers a number of natural hot springs and geothermal pools where visitors can enjoy a warm, relaxing swim. The Blue Lagoon, located near Reykjavik, is the most famous of these, but there are numerous other geothermal spots scattered across the country. These hot springs are an excellent alternative to cold ocean swimming, providing an unforgettable bathing experience surrounded by stunning volcanic landscapes. In addition to these pools, there are also several natural hot river baths, like those in Reykjadalur, which provide a unique way to enjoy the warmth of Iceland’s geothermal activity.

While Iceland may not be a traditional swimming destination due to its cold waters, it offers a unique combination of cold-water experiences, hot springs, and a variety of outdoor activities such as kayaking, whale watching, and diving. The country's coastal waters, particularly near glaciers and icebergs, provide a rare opportunity for those seeking a more rugged, adventurous encounter with the sea.

Iceland Weather

Iceland has a subarctic and oceanic climate, influenced by the North Atlantic Ocean and the Gulf Stream. Summers, from June to August, are cool and mild, with average temperatures ranging from 50°F to 60°F (10°C to 16°C). The coastal areas, including Reykjavik, experience slightly warmer temperatures, while the highlands remain much cooler. Rainfall is frequent throughout the year, and summer often brings cloudy skies and occasional strong winds. Despite the cool weather, Iceland enjoys long daylight hours in summer, with the Midnight Sun providing almost 24 hours of light in June.

Winters, from December to February, are cold but not as extreme as in some other northern regions, with temperatures generally between 20°F and 35°F (-7°C to 2°C). The coastal areas stay milder due to the ocean’s influence, while inland and northern parts can experience lower temperatures. Snowfall is common, especially in the mountains, but rain and strong winds are also frequent in winter. The limited daylight during the winter months, with as little as four to five hours of sunlight in December, creates a dramatic and unique atmosphere. Despite the cold, Iceland’s climate is relatively moderate compared to its latitude, thanks to the warming effects of the surrounding ocean currents.
