*** 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 of Gile Flowage experiences marked seasonal changes in surface temperature because it is a northern Wisconsin impoundment. In spring (April–May) the water commonly ranges from about 40–60°F (4–16°C) as ice melts and the lake stratifies. Summer surface temperatures typically warm to roughly 68–78°F (20–26°C) in July and August, with shallower bays sometimes reaching the upper end of that range. By early fall (September–October) surface readings usually decline to about 50–65°F (10–18°C) as cooling and turnover occur. In winter the flowage commonly freezes over; water beneath the ice is near freezing, generally about 32–39°F (0–4°C), with the coldest conditions just under the ice.
Swimming is generally possible on Gile Flowage during the open-water season where public access or informal beaches exist, but there are usually no lifeguards and conditions can vary. Seasonal factors such as cool spring and fall temperatures, boat traffic, sudden depth changes, and underwater vegetation mean swimmers should exercise caution. In winter the frozen surface prevents conventional swimming; ice diving or cutting holes through the ice poses significant hypothermia and safety risks unless done with experienced supervision and proper safety measures.
