*** 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
C.S. Mott Lake in Michigan experiences the kind of seasonal temperature swings typical of small inland lakes in the region. During summer, surface temperatures commonly climb into the 70–80°F range (about 21–27°C), and on hot, calm days may reach the low 80s (around 28–29°C). In spring the lake is much cooler, often between roughly 40–60°F (4–15°C) as it stratifies and warms, while fall sees a steady decline to roughly 50–65°F (10–18°C) before winter. In winter the water approaches freezing, typically near 32–39°F (0–4°C), and ice cover is common for varying periods depending on the season.
Swimming is generally permitted only where park managers have designated and posted swim areas and when local health and safety advisories allow it. Whether swimming is open depends on water-quality testing (to check for bacteria or blue‑green algae), weather and wave conditions, the presence or absence of lifeguards, and ice or cold‑water hazards; restrictions may be posted at the site. Even in summer, swimmers should be aware of sudden temperature changes, underwater obstacles, and the risk of cold‑water shock after brief exposure to cooler layers. When authorities close the area or post warnings, it is for public safety.
