*** 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
Fish Lake in Michigan typically follows the temperature patterns of shallow-to-moderate inland lakes in the region. Surface water in winter hovers near freezing, about 32–40°F (0–4°C) under ice or in late winter, while spring sees a steady rise into the 40–60°F (4–15°C) range as the lake mixes. In summer the warmest surface readings are often between roughly 68–78°F (20–26°C), with shallow bays sometimes reaching around 80°F (27°C) on hot, calm days. By fall the surface cools again to about 50–65°F (10–18°C). Deeper water remains colder year-round and thermoclines can form in summer, so temperatures drop quickly with depth; winter ice cover produces uniformly cold conditions.
Swimming is commonly allowed on Fish Lake at public access sites and private shorelines, because there is no single statewide prohibition on swimming in inland lakes; however access and rules vary locally. The lake’s summer surface temperatures are generally comfortable for recreation, but swimmers should be mindful of colder deep water, sudden temperature changes, potential algal blooms in warm months, and ice safety in winter. Local signage, public beach hours, and health advisories should be checked before entering the water to ensure conditions and access are appropriate.
