Water Temperature: Daily Trends, Historical Records, and Forecast
❌ As of today, the minimum water temperature ranges from 50°F (10°C) to 54°F (12°C). The water is slightly warmer, but still cool for most people. Swimming in such conditions is possible, but for most people, the time spent in the water should be limited to avoid hypothermia. Even experienced swimmers may feel discomfort if they stay in the water for too long. To improve comfort and safety, a wetsuit 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
Wyman Lake in Maine follows the seasonal temperature patterns typical of small inland New England lakes. Surface temperatures in summer commonly range from about 68 to 75°F (20 to 24°C), and in late, warm summers can briefly reach the mid-70s to upper-70s°F (24–26°C). Spring and early summer waters are much cooler, often between 40 and 60°F (4 to 16°C) as the lake mixes and warms. By fall the surface usually cools again to roughly 45 to 60°F (7 to 16°C). Deeper water remains significantly colder year-round—often in the 40s°F (4–10°C) when the lake is stratified—so submersion beyond the thin warm surface layer can expose swimmers to cold temperatures quickly. In winter the lake approaches freezing, with ice cover possible when conditions permit.
Swimming at Wyman Lake is commonly done during the warm months, but whether it is advisable or allowed depends on location and local rules. Many shore areas are suitable for recreational swimming when water is warm, but some areas may be posted, privately owned, or unsafe because of steep drop-offs, cold deeper water, boat traffic, or fluctuations in levels and currents. There are generally no lifeguards, so swimmers should exercise caution, be aware of cold-water shock, and respect signage and property boundaries before entering the water.
