*** 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 Bomoseen’s surface temperatures change markedly through the year. In spring (April–May) water typically runs cool, roughly 40–60°F (4–16°C) as the lake stratifies. By summer (June–August) surface readings commonly rise to about 68–78°F (20–26°C) in the warmest stretches and shallow bays, while deeper water stays noticeably cooler. Early fall (September–October) sees a gradual decline, often 50–70°F (10–21°C), before the lake cools toward freezing. In winter the surface is frequently at or below 32°F (0°C) where ice forms; under the ice the water remains just above freezing. These averages can vary with weather, wind, and localized shallow areas that warm more quickly.
Swimming is allowed in Lake Bomoseen, particularly at designated public beaches and day-use areas maintained for recreation, because summer surface temperatures are often warm enough for comfortable bathing and local authorities monitor conditions. Recreational swimming is common in July and August when surface temperatures peak, but swimmers should remember that deeper water stays colder and sudden immersion can be a shock. Periodic water-quality advisories or algal bloom notices are issued when necessary, so swimmers should heed posted guidance and use only designated swimming areas for safety.
