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
Long Meadow Lake in Minnesota experiences pronounced seasonal changes in water temperature typical of shallow Midwestern lakes. In spring and fall the surface usually ranges from about 40–60°F (4–15°C) as the lake mixes and responds to air temperature. By mid-summer surface temperatures commonly warm to roughly 68–78°F (20–26°C) on sunny days, though shallower bays can warm faster and small pockets may reach the low 80s°F (around 27–28°C). In winter the surface freezes at 32°F (0°C) and the water below the ice tends toward the densest water temperature near 39°F (4°C).
Swimming at Long Meadow Lake is generally feasible during the warmer months when surface temperatures are comfortable, and many people swim there in summer months. Whether swimming is officially allowed depends on local park regulations and posted signage; authorities may close access temporarily for safety or health reasons such as harmful algal blooms, high bacteria counts, ice cover, or lack of lifeguards. Even when open, water temperatures below about 70°F (21°C) can feel brisk to many swimmers and cooler conditions increase the risk of cold-water shock, so swimmers should heed local guidance, check current conditions, and use caution.
