*** 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
Lake Ripley, a small inland lake in Wisconsin, follows the typical seasonal pattern for Midwestern lakes. In winter the surface generally freezes and temperatures hover around 32°F (0°C), with the water just below ice only slightly above freezing. During spring the lake warms through the 40s and 50s °F (about 4–15°C) as snowmelt and cooler air keep conditions brisk. By summer surface temperatures commonly reach the upper 60s to upper 70s °F (20–26°C), and shallow bays can spike into the low 80s °F (27–28°C) on hot, calm days. In fall the lake cools back into the 50s–60s °F range (10–16°C) before refreezing.
Swimming in Lake Ripley is generally possible and is a popular recreational activity when water temperatures are comfortable, typically late spring through early fall. Public access points and private beaches are used for bathing, and people usually find water above about 70°F (21°C) most pleasant for prolonged swimming; temperatures in the 60s °F (15–20°C) feel brisk but swimmable for shorter periods. Local rules, private property boundaries, and occasional water-quality advisories — for example during algal blooms or high bacteria readings — can restrict safe swimming, so checking current conditions and posted notices is advisable before entering the water.
