Water Temperature: Daily Trends, Historical Records, and Forecast
⚠️ As of today, the minimum water temperature ranges from 54°F (12°C) to 60°F (15°C). The water is significantly warmer, and swimming becomes possible for most people. However, caution may still be required for prolonged stays in the water, as extended exposure can cause discomfort. This is a suitable temperature range for short swims and for those accustomed to cooler water. For more comfortable swimming, it is recommended to use proper gear. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

*** 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
Fox Lake in Wisconsin typically follows the seasonal pattern of shallow inland lakes in the region. During winter the surface sits near freezing, roughly 32–36°F (0–2°C) and often develops ice cover. In spring it warms through the 40s and 50s Fahrenheit as snowmelt and cooler air persist, about 4–15°C. By summer the lake’s surface commonly reaches the 70s to low 80s °F, roughly 21–28°C, with the warmest readings in shallow bays and on sunny afternoons. Autumn brings a steady decline back into the 50s and 60s °F, or about 10–18°C, as cooler nights and turnover events cool the water.
Swimming is generally allowed on Fox Lake during the warmer months because surface temperatures reach comfortable ranges for recreational use and because public access points and designated beaches support bathing and boating. Local authorities typically monitor conditions and may post advisories for algal blooms, bacterial contamination or unsafe weather; these affect whether swimming is advisable. Spring and fall waters can be uncomfortably cold for prolonged immersion, and winter swimming is not recommended because of ice hazards and near‑freezing temperatures, except where specially organized and supervised events occur. Always check current local guidance for safety and water‑quality information before entering the water.
