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
Wilson Lake in Wilson County, Kansas, typically follows the seasonal temperature patterns common to inland reservoirs in the central plains. Surface temperatures in winter often hover near freezing to the mid-40s °F (about 0–7 °C). During spring the water usually warms into the mid‑40s to mid‑60s °F (roughly 7–18 °C) but can remain cool enough to feel brisk. Summer surface temperatures frequently reach the mid‑70s to mid‑80s °F (about 24–29 °C) in warm periods, with the warmest months offering the most comfortable swimming conditions. As autumn progresses the lake cools back through the 50s and 60s °F (10–20 °C), with deeper water staying colder longer.
Swimming is generally permitted at Wilson Lake because it is managed for multiple recreational uses, including bathing, but it is typically confined to designated beaches or day‑use areas for safety and to separate swimmers from boat traffic. Temporary closures or advisories can occur for water‑quality issues such as algal blooms, high bacterial counts, or hazardous conditions, so checking current park notices is important. Outside of midsummer, water temperatures can pose cold‑water shock or hypothermia risks, and uneven bottoms and boating activity create additional hazards; visitors should heed posted signs, exercise caution, and avoid swimming alone.
