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
The Chippewa Flowage in northwest Wisconsin is a large reservoir whose surface temperatures vary substantially through the year. After ice-out in spring, surface water commonly runs about 40–60°F (4–16°C) as the lake slowly warms. Peak summer surface temperatures in July and August often reach roughly 65–78°F (18–26°C) in shallower bays and nearshore areas, though deeper or wind-exposed parts can stay cooler. By early fall the lake cools to roughly 45–62°F (7–17°C), and through winter the surface is typically at or just above freezing beneath ice cover, about 33–39°F (0.5–4°C). Temperatures vary locally with depth, wind, sunlight and proximity to inlets or the dam, so conditions at a particular access point may differ from the general ranges above.
Swimming is generally permitted because the Flowage is public water, and many visitors swim from shore, boats or campsites. There are no widespread lifeguarded beaches, however, and swimmers should be cautious: submerged stumps and vegetation, fluctuating water levels, limited visibility, and cold-water shock (especially outside mid-summer) present real hazards. For safer swimming choose shallow, sheltered areas on warm days, wear a life jacket when boating to a swim spot, and avoid entering very cold or ice-covered water.
