Lake Ontario. The reported Lake Ontario water temperature is taken at the Monroe County Water Treatment Plant near Greece, N.Y. The temperatures is measured at the intake pipes about 1500 feet offshore at a approximate depth of 35 feet.
This near surface water temperature animation was created from the latest LOOFS nowcast for the Lake Ontario. The nowcast is of the most recent surface water temperature as simulated by LOOFS when it is forced by recent observations and re-analyzed meteorological and oceanographic products.
The Lake Ontario Operational Forecast System (LOOFS) has been implemented by NOAA's National Ocean Service (NOS) to provide the maritime user community with short-term predictions of water levels, water currents, and water temperatures of the Lake Ontario.
