Water Temperature: Daily Trends, Historical Records, and Forecast
❌ As of today, the minimum water temperature ranges from 47°F (8°C) to 50°F (10°C). This is still cool water, suitable only for experienced swimmers or those accustomed to cold water. Swimming in such conditions is possible, but not recommended for prolonged periods. Extra caution should be taken during extended exposure, as the cold water can cause heat loss and lead to hypothermia. For added comfort, special clothing can be used. 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
Cobbosseecontee Lake in Maine exhibits the typical seasonal variability of a northern temperate lake. Surface water in spring often ranges from about 40–55°F (4–13°C) as the lake stratifies and warms. By early summer temperatures commonly rise to roughly 55–68°F (13–20°C), with midsummer surface readings frequently between 68–75°F (20–24°C) in sheltered, shallow areas and occasionally warmer in late heat spells. As autumn arrives the surface cools back toward 50–60°F (10–16°C) before dropping to near freezing under ice in winter, commonly around 32–39°F (0–4°C) beneath the cover. Temperatures vary with depth, location, wind, and recent weather, so deeper basins remain distinctly cooler than sunlit shallows.
Swimming on Cobbosseecontee is generally allowed and is a common recreational use during the warm months because summer surface temperatures are often comfortable for bathing. Public access points and private beaches provide places to enter the water, but conditions are not uniformly ideal: aquatic vegetation, boat traffic, sudden drop-offs, and occasional algal issues can affect safety and enjoyment, and lifeguards are not always present. In contrast, winter swimming is unsafe and impractical due to ice cover and near‑freezing water temperatures, so people avoid open-water swimming outside the warmer season.
