✅ 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.

*** 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
Whalon Lake’s water temperatures follow the typical seasonal cycle for small Midwestern reservoirs. In winter the surface often approaches freezing, around 32°F (0°C), and may form ice. Spring sees a steady rise from roughly 40–60°F (4–16°C) as the water stratifies and warms. During summer the lake commonly reaches the 70s °F, about 21–27°C, and on warm spells the surface can climb into the low 80s°F (27–29°C). By autumn temperatures fall back into the 45–65°F range (7–18°C) as cooling and turnover occur. Local weather, depth, wind and shading from trees can all produce short-term variation from these typical values.
Swimming at Whalon Lake is generally not permitted for the public, because the site is managed primarily for fishing, wildlife habitat and non‑lifeguarded boating rather than as a supervised bathing beach. There are no designated, lifeguarded swim areas or routine beach monitoring, and managers restrict swimming to reduce risks from boat traffic, submerged hazards and occasional water‑quality issues such as algal blooms. For safe recreational swimming nearby, visitors should seek official public beaches or pools that post current water‑quality and lifeguard information.
