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
Dutch Hollow Lake, like many small inland lakes in Wisconsin, experiences a strong seasonal cycle in surface water temperature. After ice-out in spring, surface waters commonly range from about 40–55°F (4–13°C) as the lake mixes and warms. By summer the surface often reaches comfortable swimming temperatures, typically around 68–78°F (20–26°C), with shallow bays occasionally climbing into the low 80s (27–28°C) on hot, calm days. In early fall the surface cools back into the 50s–60s°F (10–18°C) range before ice returns; during winter the lake is generally at or below freezing near 32°F (0°C) where it is ice-covered.
Swimming on Dutch Hollow Lake is generally possible during the ice-free months because summer temperatures regularly attain ranges comfortable for recreational swimming and boating access is available from shoreline properties and community areas. Whether swimming is allowed at a particular spot depends on local rules and posted advisories administered by the lake association or local authorities; water-quality issues such as algal blooms, hazardous currents, or lack of lifeguards can prompt temporary restrictions. Visitors and residents should follow posted guidance, check for water-quality advisories, and use standard open-water safety precautions.
