*** 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 of Dells Pond, like many small inland waters in Wisconsin, shows pronounced seasonal swings in surface temperature. During winter the pond typically reaches near-freezing conditions around 32°F (0°C) under ice cover. In spring, as ice breaks up and air temperatures rise, surface readings commonly climb from the low 40s to the upper 50s °F (5–15°C). Peak summer temperatures tend to fall in the 70s to low 80s °F (21–28°C) in shallower areas, with the warmest afternoons occasionally pushing mid-80s °F (around 29°C) in very warm spells. By autumn the water cools again, often settling in the 50s to low 60s °F (10–17°C) before refreezing. Deeper pockets, if present, remain cooler through summer and can create stratification that affects overall temperature readings.
Swimming opportunities at Lake of Dells Pond depend on access, local rules, and water quality rather than temperature alone. When shorelines are open and bacterial or algal advisories are not in effect, people commonly swim during the warm months because surface temperatures are comfortable for recreational use. However, seasonal hazards — cold shock in early spring or hypothermia in cooler fall water, submerged vegetation, and occasional blue‑green algae blooms — can restrict safe swimming. It’s advisable to follow posted signs and check with local authorities about permitted uses and current water‑quality conditions before entering the water.
