*** 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
Wister Lake’s surface water temperature varies with the seasons and daily weather, typically running cold in winter and warm in midsummer. Typical seasonal surface ranges are roughly winter 40–55°F (4–13°C), spring 50–70°F (10–21°C) as warming progresses, summer 75–85°F (24–29°C) at the warmest, and autumn 60–75°F (16–24°C) as cooling begins. These figures reflect surface conditions; deeper water remains significantly colder year-round due to stratification, and short-term swings occur after heavy rain or cold snaps. Anglers and boaters will notice the lake temperature has a strong influence on fish activity and seasonal patterns.
Swimming at Wister Lake is generally permitted because it is a public recreation reservoir, and many visitors swim from shore or boats during warm months. Recreational swimming is most comfortable when surface temperatures exceed about 70°F (21°C), typically late spring through early fall. However, there are rarely staffed lifeguards, water quality can vary, and occasional algal blooms, strong currents near inlets or boat traffic, and submerged hazards mean swimmers should exercise caution, heed posted advisories, and check local notices for temporary closures or safety recommendations.
