*** 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
Pomme de Terre Lake in west-central Minnesota experiences marked seasonal swings in surface water temperature. In summer months (June–August) typical surface readings most often fall between about 70–80°F (21–27°C), and can rise into the low-80s (around 28–29°C) during heat waves. Late spring and early fall commonly show cooler surface temperatures in the 50–68°F range (10–20°C), while by late fall and winter the lake cools toward 40–50°F (4–10°C) and then to near freezing once ice forms, roughly 32–35°F (0–2°C). Temperatures vary with depth, wind, and recent weather, so sheltered bays may be warmer than open-water areas and surface readings on calm days will differ from well-mixed conditions after storms.
Swimming is permitted at many recreational spots around Pomme de Terre Lake, and the lake is used for open-water swimming, beach use and boating-related recreation during the warmer months. Seasonal temperature trends and the presence of boating traffic, occasional algal blooms, and ice cover in winter make it important to choose designated swim areas and heed local advisories; water can be uncomfortably cold or hazardous outside the warmest weeks. Lifesaving services and rules vary by site, so checking current conditions before entering the water is advisable.
