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
Sunrise Lake, like many small lakes in Minnesota, experiences marked seasonal shifts in surface water temperature. In winter the lake commonly sits at or just below freezing at the surface (around 32°F / 0°C) and is often ice-covered. During spring thaw surface temperatures typically climb from roughly 34–55°F (1–13°C) as the water mixes and warms. In summer the surface usually reaches its warmest, commonly in the range of about 68–78°F (20–26°C), with shallow bays and sunlit areas occasionally reaching the low 80s°F (27–28°C); deeper layers remain appreciably cooler, often 45–55°F (7–13°C), due to thermal stratification. In autumn the surface cools again to roughly 50–60°F (10–16°C) before refreezing.
Swimming is generally possible during the ice-free months when surface temperatures are comfortable, provided there is legal access and no current water-quality advisories. Authorities or property owners may restrict access, and occasional issues such as algal blooms or bacterial contamination can affect safety, so local notices should be checked. Winter swimming through ice holes occurs in some communities but carries significant risk from thin ice and cold-water shock and is not recommended without proper safety measures. Overall, recreational swimming at Sunrise Lake depends on season, water temperature, and local rules or health advisories.
