Water Temperature: Daily Trends, Historical Records, and Forecast
✅ As of today, the minimum water temperature is above 82°F (28°C). This is very warm water, which may feel almost hot to most people. Swimming in such conditions is perfect for those seeking relaxation and comfort in the water. These waters are often preferred for relaxation in hot weather, as the water temperature does not cool the body significantly. However, it is important to remember that in such warm waters, caution is necessary, as prolonged exposure without rest can lead to overheating. 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
Lake Minnewashta, located in suburban Minnesota, follows the familiar seasonal pattern of small temperate lakes. In winter the surface freezes and water temperatures close to the ice hover at or below 32°F (0°C), with deeper water a few degrees warmer. Spring brings a gradual warming from roughly 35–60°F (2–15°C) as snowmelt and air temperatures fluctuate. By summer, surface waters commonly reach comfortable swimming levels, often ranging from about 65–78°F (18–26°C) at peak warmth, with variability depending on sunlight, wind and lake depth. Early fall sees a steady cooling back into the 50–65°F (10–18°C) band before the lake returns to winter conditions.
Swimming is typically allowed at Lake Minnewashta during the warmer months where designated beaches or park areas are maintained, because summer surface temperatures frequently support recreational paddling and swimming. However, access and safety are governed by local authorities; swimming may be restricted or discouraged when water quality tests indicate high bacterial counts, when harmful algal blooms appear, or when weather and ice conditions create hazards. Visitors should therefore use marked swim areas, heed posted advisories, and be aware that short-term temperature drops and subsurface cold pockets can make water feel much colder than air temperatures suggest.
