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
Coon Lake in Minnesota experiences the broad seasonal swings typical of shallow temperate lakes. In spring (April–May) surface temperatures commonly rise from roughly 45–60°F (7–16°C) as ice melts and the water stratifies. By summer (June–August) the upper layer often warms to comfortable swimming temperatures, frequently in the range of about 68–78°F (20–26°C) and on warm afternoons reaching around 80°F (27°C). In autumn (September–October) surface readings usually fall back to roughly 50–65°F (10–18°C) as cooling and turnover occur. Through winter the lake is normally at or just above freezing under ice cover, near 32–36°F (0–2°C) in the upper waters, while deeper water remains near 39°F (4°C).
Swimming at Coon Lake is a common recreational use during the warmer months because surface temperatures in summer are often within a comfortable range for most people. Whether and where you can swim depends on shore access, designated beaches or public access points, and current conditions: water-quality advisories (for bacteria or algal blooms), submerged vegetation, boat traffic and the absence of lifeguards can all affect safety and suitability. For safe, enjoyable swimming aim for the mid-summer period when surface temperatures exceed about 70°F (21°C), and always check local advisories and respect posted rules before entering the water.
