*** 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 Chaubunagungamaug, commonly called Webster Lake in Massachusetts, warms and cools with the New England seasons. Typical surface temperatures in spring run from roughly 40–60°F (4–16°C) as the lake recovers from ice cover. By summer, surface readings commonly reach about 68–79°F (20–26°C), and on the warmest afternoons can approach 80°F (27°C) in shallow bays. Autumn brings cooling into the 50–65°F (10–18°C) range as stratification breaks down, and winter surface temperatures sit near freezing, roughly 32–39°F (0–4°C), often with shore ice and occasional full ice cover. Deeper water remains cooler than surface readings in summer, so swimmers may notice a sharp temperature difference when moving away from shallow areas.
Swimming at Lake Chaubunagungamaug is generally allowed and is popular in summer at public beaches and private shorelines where access is permitted. Local authorities and beach managers typically monitor conditions and post advisories; closures can occur for reasons such as elevated bacterial counts or harmful algal blooms, so checking current notices before entering the water is important. Lifeguards may be present at managed beaches, but open-water swimmers should observe safety practices, be mindful of boat traffic, and avoid winter swimming unless in supervised, cleared areas.
