GOUVERNEUR, NY

Overview:
Gouverneur, NY sits on the western edge of the Adirondack Mountains, and it is located in the lowlands of the St. Lawrence River approximately 50 miles northwest of Lake Ontario. Moderate summers give way to very cold winters due to the city’s location in the Oswegatchie River Valley.

Normal maximum temperatures are below freezing from December through February, while minimum temperatures in January and February are below 6°F. Precipitation is normally highest during autumn compared to southern New York, which receives more in the summer. Lake effects are minimal for snowfall in the winter, as Gouverneur averages 20 fewer days with measurable snow than Oswego, NY. The sustained cold keeps snowfall on the ground for nearly 100 days per year on average.

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.
