Norwegian Sea Water Temperature Today & Regional Overview
We find every place where you can swim and show you the water temperature there today and throughout the year.
Current Water Temperature
The water temperature in the Norwegian Sea today ranges from 7.3°C (Sørfjord, Norway) to 13.6°C (Straumen, Norway).
As of today, the minimum water temperature in the Norwegian Sea ranges from 41°F (5°C) to 47°F (8°C). This water temperature is still quite low, and swimming in such conditions may only be comfortable for hardened individuals. It is recommended to limit the time spent in the water to avoid hypothermia. For those not accustomed to cold water, it is better to refrain from swimming. However, if you decide to enter the water, it is advisable to wear a warm wetsuit for protection against the cold.
It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.
Sea Temperature Trends
Over the past month, the water temperature in the Norwegian Sea has increased by 5°C. In general, the sea water temperature remains within the statistical range for this time of year.

The Norwegian Sea experiences a broad range of surface temperatures that change with season and location. Thanks to the North Atlantic Current the sea is milder than other waters at similar latitudes, but remains cool year-round. Typical winter surface temperatures in the central and northern parts of the Norwegian Sea are generally between about -1 °C and 4 °C, while coastal and southern areas seldom drop below 2 °C to 8 °C in the coldest months. In summer the central sea commonly warms to roughly 6 °C to 12 °C, and nearer the sheltered fjords and southern coastal pockets temperatures can occasionally rise to 15 °C or more on warm, calm summers. These figures vary with depth, local currents, wind-driven mixing and freshwater input, so conditions at a particular beach may differ noticeably from open-sea measurements.
Swimming Conditions
Swimming in the Norwegian Sea is permitted and frequently practiced, particularly during the warmer months and in sheltered coastal spots, but it requires caution because the water remains cold compared with temperate or tropical seas. Short swims, shore entries and the use of wetsuits are common to reduce the risk of cold shock and hypothermia; organized cold-water swimming communities also follow safety measures such as gradual acclimatization and supervision. Winter and off-season swims are undertaken by experienced cold-water swimmers with appropriate gear and safety support; for most visitors, bathing is safest in summer, on calm days and when lifeguards or local guidance are available.
