*** 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
Hargus Lake’s water temperature will follow the typical seasonal patterns of small to medium inland lakes in Ohio, though exact values depend on depth, shading, and recent weather. In winter the surface often hovers near freezing, roughly 32–40°F (0–4°C). Spring warming tends to raise surface temperatures into the 40–60°F range (4–16°C) as ice melts and air temperatures climb. In summer, shallower areas and the epilimnion can reach about 70–80°F (21–27°C) and occasionally warm to the low 80s°F (27–29°C) during prolonged heat, while deeper water remains cooler. Fall sees a gradual decline, with typical surface temperatures of 50–65°F (10–18°C) as cooling resumes. These are broad seasonal ranges; hourly and daily values will vary with wind, sun, and inflows.
Whether swimming is allowed at Hargus Lake depends on ownership and local rules: public lakes or parks with designated beaches usually permit swimming, while private or conservation-managed waters may prohibit it. Even where allowed, swimmers should heed posted advisories because safety and water quality can limit access—reasons include harmful algal blooms, elevated bacteria levels, submerged hazards, or cold-water shock in shoulder seasons. Visitors should verify current local signage or contact the managing authority before entering the water.
