BOONVILLE, NY

Overview:
Boonville is located approximately 60 miles east of Lake Ontario. Apart from a few small streams and creeks running throughout the area, Boonville has few other distinguishing water bodies. The topography ranges from the nearly level terrain of river valleys to very steep hillsides in the foothills of the Adirondack Mountains, in the northeastern part of the region.

Boonville is typically cold and snowy in winter and warm to hot in summer. Days exceeding 90ºF occur extremely rarely, while wintertime temperatures below freezing are to be expected often with occurrences over 150 days annually. Precipitation is well distributed during the year and is adequate for most crops on most soils. From late fall through winter, snow squalls are frequent in various parts of the county, and total snowfall is normally heavy.

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.
