*** 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
Chain Lake in North Dakota experiences marked seasonal changes in surface water temperature. In spring, as ice melts, surface temperatures commonly rise from near freezing to roughly 40–55°F (4–13°C). By summer the upper water can warm to around 68–78°F (20–26°C), with shallower areas occasionally reaching the low 80s °F (about 27–28°C) on hot spells. Early autumn typically sees cooling to roughly 50–65°F (10–18°C) before the lake begins to lose heat and freeze. In winter the surface is generally at or below freezing, around 32°F (0°C), and many lakes in the region are ice-covered for months.
Swimming is generally possible at Chain Lake when open water conditions prevail, but it depends on local regulations, access points and water-quality conditions. People commonly swim in summer when surface temperatures are warm enough for comfort, though cooler depths can be significantly colder. Swimmers should be mindful that official lifeguards are rarely provided at smaller rural lakes, and seasonal hazards such as sudden drop-offs, aquatic vegetation, or harmful algal blooms can affect safety and water quality. Always check current local advisories and signage before entering the water, avoid swimming when ice is present, and take usual precautions for cold-water exposure.
