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
Brookville Lake’s surface water temperatures vary considerably through the year. In summer months (June–August) surface readings commonly climb into the mid‑60s to mid‑80s °F (about 18–29 °C), making conditions pleasant for many swimmers. Spring (March–May) typically brings cooler water, often in the 40s to low‑60s °F (4–17 °C) as runoff and cooler air keep the reservoir chilly. In fall (September–November) temperatures usually decline into the 50s to low‑70s °F (10–22 °C) before winter sets in, when surface temperatures approach freezing — roughly 32–40 °F (0–4 °C) — and ice or near‑ice conditions are possible on shallower bays. Deeper water remains colder year‑round.
Swimming is allowed in recreational parts of the lake, but it is generally at your own risk and subject to posted rules and seasonal restrictions. Many access points do not have lifeguards, and swimmers should be mindful of boat traffic, sudden depth changes, submerged timber, and variable currents that can make conditions hazardous despite warm surface readings. Because of these factors, full safety precautions — life jackets for weaker swimmers and awareness of local signage and weather — are recommended before entering the water.
