Lake Erie temperature updated : September 16, 2008 Latest Lake Erie Temperature The 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. The Lake Ontario temperature occasionally may not be representative of the surface temperature due to upwelling. This process, more common during the summer months, brings colder water from the deeper parts of the lake toward the surface near the temperature sensor. The surface water may be significantly warmer.  Lake Ontario temperature updated : September 16, 2008 Latest Lake Ontario Temperature Great Lakes ice cover and water temperature information measured by satellite can be obtained at the Great Lakes Environmental Laboratory site.  Lake Erie Daily Min, Max and Average Temperatures Historical Table of Lake Erie Water Temperatures: (Record Min, Max and Average for each day of the year)  Annual Lake Erie Water Temperature Graphs Click on the year to get a graph of the daily temperature and the average for each day   1930 1940 1950 1960 1970 1980 1990 2000   1931 1941 1951 1961 1971 1981 1991 2001   1932 1942 1952 1962 1972 1982 1992 2002   1933 1943 1953 1963 1973 1983 1993 2003   1934 1944 1954 1964 1974 1984 1994 2004   1935 1945 1955 1965 1975 1985 1995 2005   1936 1946 1956 1966 1976 1986 1996 2006 1927 1937 1947 1957 1967 1977 1987 1997 1928 1938 1948 1958 1968 1978 1988 1998 1929 1939 1949 1959 1969 1979 1989 1999 Minimum Temps on Record Average Maximum Temps on Record Max/Min/Average Combination Graph Local Climate Water & Weather Topics: Current Hazards, Current Conditions, Radar, Satellite, Climate, Weather Safety, Contact Us National Weather Service Weather Forecast Office Buffalo 587 Aero Drive Buffalo, N.Y. 14225-1405 (716)565-0204 or (716)565-0802 Webmaster:Webmaster Page last modified: February 4, 2008 Disclaimer Credits Glossary Privacy Policy About Us Career Opportunities
