*** 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

Pleasant Hill Lake in Ohio experiences a pronounced seasonal cycle in water temperature. In summer, surface temperatures commonly reach about 75–85°F (24–29°C) during July and August, which is when the lake feels most comfortable for swimming. Spring brings cooler conditions with surface readings often ranging from roughly 45–68°F (7–20°C) as the water warms; in autumn the surface typically falls back to about 50–70°F (10–21°C) as cooling sets in. Winter temperatures can approach freezing, with surface water near 32–40°F (0–4°C) and ice possible in cold spells, while deeper water remains noticeably colder year-round because of stratification and limited mixing.

Swimming opportunities at Pleasant Hill Lake are governed by park rules and seasonal management. Recreational swimming is generally permitted only in designated areas when the park opens them, largely for safety and water-quality reasons; lifeguards are not always on duty and boat traffic, submerged hazards and sudden cold pockets make unsupervised swimming riskier. Authorities may close or post advisories for harmful algal blooms, contamination, or unsafe conditions, so visitors are advised to follow posted signs and current park guidance before entering the water.
