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
Clear Fork Reservoir in Ohio experiences a strong seasonal cycle in water temperature typical of Midwestern reservoirs. During winter months surface temperatures commonly approach freezing, roughly 32–40°F (0–4°C), and the lake can freeze over in prolonged cold. Spring brings a steady warm-up with surface readings often in the 40–60°F range (4–16°C) as stratification begins. In summer, surface waters typically warm to about 68–78°F (20–26°C), with the warmest readings in July and August; deeper layers remain noticeably cooler, often 10–15°F (6–8°C) below the surface, due to thermal stratification. Autumn sees a gradual cooling back into the 50–68°F band (10–20°C) before winter refreezing. Short-term fluctuations occur with weather, inflow, and wind-driven mixing, so single-day temperatures can differ from seasonal averages.
Swimming at Clear Fork Reservoir is generally restricted for reasons of water quality and public safety. Many reservoirs that serve as municipal or regional water supplies prohibit open-water bathing to protect drinking-water sources from contamination and to limit liability risks; additionally, the absence of designated beaches, lifeguards, underwater hazards, and variable currents make unsupervised swimming unsafe. Where recreational use is allowed, authorities typically confine activities to marked areas or nearby parks that meet safety and environmental standards, so visitors should follow local rules and posted signs before entering the water.
