Water Temperature: Daily Trends, Historical Records, and Forecast
❌ As of today, the minimum water temperature 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.

*** Forecast - Our water temperature forecast
Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.

The Hay River, flowing through northwestern Alberta before crossing into the Northwest Territories and emptying into Great Slave Lake, experiences significant temperature variations throughout the year due to its northern location. In early spring, the river is still partially ice-covered, and surface temperatures average around 35–39°F (2–4°C). As snowmelt accelerates in late May and June, the water warms slightly to about 46–54°F (8–12°C). During midsummer, particularly in July and August, the upper sections of the river can reach 59–64°F (15–18°C), with shallow areas occasionally approaching 68°F (20°C) on warm days. By late September, cooling air and shorter days bring the temperature back below 52°F (11°C), and the river begins to chill rapidly heading into autumn.
Swimming in the Hay River is possible but not common due to the cold water and variable current. Even in summer, temperatures remain brisk, and hypothermia can develop after extended exposure. The river is better known for fishing, canoeing, and sightseeing along its scenic banks than for recreational swimming. In calm, shallow sections, especially during warm midsummer afternoons, short dips may be comfortable, but caution is always advised. The Hay River is best appreciated for its rugged northern beauty and its importance to local ecosystems rather than as a traditional swimming destination.
