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.

Location & Local Information
Tagish Lake, located in the Yukon and Northern British Columbia, is a large, deep, glacial-fed lake, which results in perpetually cold water temperatures. The lake is part of the extensive Yukon River watershed, and its large volume prevents significant warming. Even during the peak summer months, the surface water temperature is severely cold, rarely rising above 10∘C (50∘F), and sometimes averaging as low as 4∘C (39∘F). In the winter, the water is near the freezing point, often remaining around 0∘C to 4∘C (32∘F to 39∘F), with the lake freezing over completely.
Swimming in Tagish Lake is strongly discouraged and exceptionally hazardous. Due to the glacial water temperature, there is an immediate and extreme risk of cold shock and rapid hypothermia, with death possible after just a few minutes of immersion without proper protective gear. The lake lacks official, designated swimming beaches and is subject to sudden, strong winds which can create dangerously rough waters. Any suggestion of casual recreational swimming is strongly opposed by local authorities and wilderness operators. All water-based activities, like kayaking and canoeing, carry the inherent risk of hypothermia, making caution and the mandatory use of life jackets essential.
