*** 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
Devil Lake in New York experiences the same seasonal shifts common to small temperate lakes. Surface waters are near freezing in winter, often around 32°F (0°C) where ice forms and open-water swimming is not feasible. In spring the lake warms gradually, with typical surface temperatures rising into the 40–60°F range (4–16°C) as ice melts and air temperatures increase. By mid to late summer the surface frequently reaches the mid-to-upper 60s up to the high 70s °F (about 18–26°C), though exact values depend on depth, shading, and local weather; shallow bays can warm faster and sometimes exceed 80°F (27°C) on hot spells. Autumn brings steady cooling, with surface temperatures usually falling back through the 50–60°F range (10–16°C) before ice reformation.
Swimming at Devil Lake is generally possible during the warm months when water temperatures are comfortable and access is permitted, but whether it is allowed depends on local rules, posted signage, and water-quality conditions. Cold shock remains a concern whenever temperatures are below about 70°F (21°C) for inexperienced swimmers, and seasonal issues like harmful algal blooms, bacteria, or submerged hazards can lead authorities to limit or advise against swimming. Always confirm current advisories, observe posted rules, and take standard safety precautions such as swimming with others and avoiding alcohol.
