Arctic Ocean 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 Arctic Ocean today ranges from -0.9°C (Kugluktuk, Canada) to -0.4°C (Pangnirtung, Canada).
As of today, the minimum water temperature in the Arctic Ocean ranges less than 41°F (5°C). Such water is extremely cold and not recommended for swimming without proper preparation. In these conditions, the risk of hypothermia is very high, and prolonged exposure to the water can be hazardous to your health. If you decide to swim, it is important to have the appropriate gear, such as a wetsuit. Typically, only experienced swimmers or those who practice winter swimming venture into such waters.
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 Arctic Ocean has remained almost unchanged. In general, the sea water temperature remains within the statistical range for this time of year.

The Arctic Ocean is characterized by very cold surface waters that vary seasonally and by location. In winter the ocean surface is typically at or just below the freezing point of seawater, roughly −2 °C to 0 °C where sea ice is present. In summer, when sea ice retreats in many areas, surface temperatures generally rise but remain low: central Arctic waters commonly range from 0 °C to about 4 °C, while more southerly or coastal marginal seas such as parts of the Barents or Chukchi regions can warm to roughly 4 °C to 10 °C in the warmest months. Local conditions such as river inflows, shallow shelves, ocean currents and seasonal sunlight can produce higher or lower readings, but overall the Arctic stays close to freezing much of the year, and persistent ice or slush can limit open-water exposure outside the brief summer window.
Swimming Conditions
Swimming in the Arctic is not broadly prohibited, but practical and safety considerations make unprotected swimming inadvisable for the general public. Very cold water produces cold shock, rapid loss of motor control and fast onset hypothermia; at temperatures near 0 °C even strong swimmers become incapacitated within minutes. Organized polar plunges and scientific or expedition swims occur, typically with safety crews, thermal protection such as wetsuits or drysuits, limits on immersion time, and medical support. Access is also constrained by sea ice, remoteness, and local regulations in protected or indigenous-use areas. Anyone considering entering Arctic waters should be aware of the extreme thermal hazards and follow expert guidance, appropriate equipment and emergency planning.
