*** 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
Lake Kampeska, near Watertown, experiences marked seasonal shifts in water temperature. In spring, surface temperatures typically rise from roughly 40–60°F (4–16°C) as runoff and warming air increase the lake’s heat. By early summer the water often sits around 60–70°F (16–21°C), and in midsummer surface readings commonly reach 70–80°F (21–27°C), occasionally climbing into the low 80s (about 27–28°C) during hot spells. In autumn the lake cools back through the 50s to near freezing — roughly 50–60°F (10–16°C) early in the season and falling toward 32–40°F (0–4°C) by late fall. Winter brings ice cover and temperatures at or below 32°F (0°C), with thickness varying year to year.
Swimming in Lake Kampeska is generally allowed and is a typical summer activity because of public access points and shoreline parks, but conditions govern whether it is advisable on any given day. Warm summer temperatures make open-water swimming comfortable, yet local advisories for water quality, such as harmful algal blooms, can temporarily close areas. Safety considerations include variable underwater conditions, boat traffic, absence of lifeguards at many spots, and hypothermia risk outside peak summer; visitors should heed posted rules and current water-quality and ice-safety information before entering.
