*** 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
Copake Lake, in Columbia County, typically follows the temperature patterns of small, temperate northeastern lakes. In spring (April–May) surface temperatures generally run about 40–60°F (4–16°C) as the water slowly warms. By early summer (June) temperatures often reach roughly 60–70°F (16–21°C), peaking in July and August when surface readings commonly sit between 70–80°F (21–27°C) on warm afternoons. As autumn arrives the surface cools back toward about 50–65°F (10–18°C) in September–October, and in winter the lake will approach freezing with surface temperatures near 32°F (0°C) and ice cover likely for portions of the season. Deeper water layers remain colder year‑round.
Swimming is a common summertime activity when surface temperatures are in the comfortable 70s°F (20s°C), but availability depends on shoreline access and local rules; some areas are private and public access points may not have lifeguards. Bathing is not recommended during cold spring or fall temperatures or when ice is present in winter. As with many inland lakes, occasional water‑quality issues such as algal blooms can lead to temporary advisories, so swimmers should heed local notices, avoid areas with visible scum, and use caution when conditions are uncertain.
