Cayuga Lake Water Temperature & Weather

The north-south orientation and length (fetch) of the lake means waves are most significant with northerly or southerly winds.

Cornell University monitors the winds and temperatures (air & water) near the southern end of the lake and makes 7-day plots available on their website.  Note that the temperatures are in degrees Celsius.
