CANTON, NY

Overview:
Located in upstate New York, Canton sits near the middle of St. Lawrence county, close to the Canadian border. Canton is bisected by Grass River, but otherwise, the land remains developed. Some small mountain ranges exist nearby to the south, but this region remains mostly flat.

Summertime temperatures are usually mild, averaging the mid-60°Fs but exceeding 90°F about two days per year. Wintertime temperatures are frequently cold, falling below freezing (32°F) over 150 days per year. Most of the region’s annual precipitation falls during late summer and early fall. Extreme precipitation events occur infrequently, under half a week per year. Thunderstorms, mostly in the summertime, occur about 28 days each year.

State/ Province ID: NY

Annual High and Low Temperature Departure

Cold Temperatures

¹Heating Degree Days (HDDs) are indexed units, not actual days, that roughly describe the demand to heat a building. HDDs accumulate on days colder than 65°F when heating is required. Every degree below 65°F is added to the annual total for an annual HDD value, which is plotted in the figure.

Hot Temperatures

²Cooling Degree Days (CDDs) are indexed units, not actual days, that roughly describe the demand to cool a building. CDDs accumulate on days warmer than 65°F when cooling is required. Every degree above 65°F is added to the annual total for an annual CDD value, which is plotted in the figure.
