About Chautauqua County Weather
Temperate but Snowy by National Standards
Chautauqua County averages 49.3°F annually, which is cooler than the national median but warmer than many of its upstate neighbors. Its position along Lake Erie creates a unique climate dominated by lake-effect moisture.
Warmer Than the State Average
The county's 49.3°F average temperature sits nearly two degrees higher than the New York state average of 47.4°F. This is due in part to the moderating influence of the Great Lakes.
The Snow King of the Region
Chautauqua receives a massive 132.8 inches of snow annually, far exceeding Cattaraugus’s 122.1 inches. Despite the snow, it is warmer than Cattaraugus by over three degrees on average.
Massive Snowfall and Pleasant Summers
While winters are snowy with 132.8 inches of accumulation, January stays relatively mild at 26.5°F compared to inland counties. July averages 71.3°F with only 5 days of extreme heat per year.
Serious Snow Management Required
The 132 inches of annual snow requires heavy-duty removal equipment and specialized roof maintenance. Summer cooling needs are minimal, but moisture control is important given the 43.3 inches of annual precipitation.
