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.

The Genesee River, flowing through New York and Pennsylvania, is a historically significant waterway that passes through diverse landscapes, from rural areas to the urban environment of Rochester. Its water temperature varies widely depending on the season. In winter and early spring, the water is cold, often ranging between 35°F and 50°F (2°C to 10°C), due to snowmelt and cooler weather. During summer, temperatures can climb to around 65°F–75°F (18°C–24°C) in calmer and slower-moving sections, making the water more comfortable for recreational activities.
Swimming in the Genesee River is not widely practiced, primarily due to safety concerns such as variable water quality, strong currents, and debris in certain areas. However, there are designated swimming spots nearby, such as in Letchworth State Park, where the river runs through dramatic gorges and waterfalls. The river is more commonly enjoyed for fishing, boating, and hiking along its scenic trails. For those looking to swim, it’s best to seek out monitored swimming areas or nearby lakes with established beach access.
