*** 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
Claytor Lake’s surface waters vary considerably through the year. In spring the lake typically cools from around 45–65°F (7–18°C) as runoff and cooler air temperatures dominate; by summer surface temperatures commonly reach about 70–82°F (21–28°C) on warm days, making the water most comfortable for recreational use. Autumn brings gradual cooling, often placing the lake in the 55–70°F (13–21°C) range, while winter temperatures can fall to roughly 32–45°F (0–7°C) at the surface, depending on air chill and ice conditions in sheltered coves. These are general seasonal ranges; local weather, depth, and inflow from the New River can shift temperatures from day to day.
Swimming is permitted at Claytor Lake, primarily in designated areas such as the swim beach at Claytor Lake State Park, where the park provides controlled public access for bathing and wading. The reason swimming is limited to marked spots is safety: the reservoir supports boating and fishing, has variable depths and submerged structures, and has currents near the dam and spillways that can be hazardous. Visitors are advised to follow posted rules, heed any advisories, and consider water temperature before entering—colder shoulder-season waters can cause shock or hypothermia even when daytime air feels mild.
