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
George Wyth Lake’s surface water temperature varies substantially through the year and is typical of shallow Midwestern lakes. In spring (roughly April–May) temperatures commonly run about 40–60°F (4–15°C) as the lake stratifies and warms. During the summer months (June–August) surface temperatures are usually in the range of 68–82°F (20–28°C), with the warmest readings in July and early August. In early fall (September–October) the water cools back into the 50–65°F (10–18°C) window, and by late fall and winter (November–March) temperatures approach near-freezing conditions around 32–40°F (0–4°C); parts of the lake can ice over in sustained cold periods.
Swimming is generally permitted in warm months at state park-designated swimming areas, but conditions and rules can change seasonally. There may not always be lifeguards on duty, so swimmers should follow posted guidance and use caution. Swimming is not appropriate when the lake is frozen or when authorities issue advisories for water quality problems such as blue‑green algal blooms; these blooms are most likely during warm summer weather and can lead to temporary closures. Checking current park signage and local advisories before entering the water is recommended for safety.
