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 Carroll’s water temperature follows a typical Midwestern reservoir pattern, with strong seasonal swings and variation by depth and weather. In winter the surface usually approaches freezing, often around 32–40°F (0–4°C), and the lake can develop significant ice cover. Spring warms unevenly as runoff and air temperatures push the surface into roughly 40–65°F (4–18°C). Summer brings the warmest conditions, with surface temperatures commonly in the 70–80°F range (21–27°C) and occasionally rising into the mid‑80s (about 29°C) during heat waves; deeper water remains noticeably cooler. In autumn the lake cools again, typically falling into the 50s–60s°F (10–18°C) before ice begins to form. Daytime heating, wind, and stratification mean conditions change quickly, so localized readings can differ from general seasonal averages.
Swimming is permitted in warm months at areas designated by the local community and property managers, primarily because summer surface temperatures are often comfortable for recreational bathing. Access and rules are set by the lake association and local authorities, and water quality advisories, algae blooms, boat traffic, or lack of supervision can affect whether swimming is advisable at any given time. In winter, near‑freezing water and ice make swimming unsafe, so recreational bathing is effectively restricted by conditions rather than by temperature alone.
