*** 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
Burntside Lake, near Ely in northern Minnesota, experiences a wide seasonal swing in surface water temperatures. In spring the surface often ranges from about 32–55°F (0–13°C) as ice melts and the water stratifies. By summer the lake usually warms to roughly 60–75°F (15–24°C) in July and August at the surface in typical years, though shallow bays can heat a few degrees warmer on hot, calm days. In early fall the surface cools again into the 40s–50s°F (4–10°C) as air temperatures drop, and in winter the lake is commonly ice-covered with surface water at or very near freezing around 32°F (0°C), while liquid water beneath the ice generally remains just above freezing.
Recreational swimming is possible and commonly practiced in the open-water months because the lake is accessible from shorelines and camps, but swimmers should be aware of local conditions. There are no widespread lifeguarded beaches, and deeper or shaded areas remain much colder than shallow bays due to thermocline and depth, so cold shock and hypothermia are real hazards even on warm days. In winter, swimming is not feasible where ice is present. As with any northern lake, checking recent local conditions, staying near shore, and using appropriate caution will make swimming safer.
