Water Temperature in Troms County: General Trends and Swimming Opportunities

Original name of the region: Troms fylke

Troms County, located in northern Norway, is known for its rugged landscapes and proximity to the Arctic Circle, which means the water temperatures along its coastline are consistently cold throughout the year. During the summer months, sea temperatures in Troms typically range from 5°C to 8°C (41°F to 46°F). Although these temperatures can be invigorating for cold-water swimmers, they remain quite chilly even during the warmer season, making swimming a bracing activity for those who are accustomed to the cold.

In winter, the temperatures of the coastal waters around Troms drop even further, averaging between 0°C and 3°C (32°F to 37°F). This means that many of the waters in the region freeze or remain close to freezing in shallow areas, although deeper waters generally stay just above freezing. The extreme cold makes recreational swimming nearly impossible during this period, but the stunning winter landscapes, including the Northern Lights, draw many visitors to the region for other outdoor activities such as dog sledding and snowshoeing. Despite the cold waters, Troms' coastline remains an essential part of the region's unique Arctic environment.
