Tupper Lake is located half way between the equator and the North Pole. The weather offers a wide range of temperatures, often a change of 150 degrees F from summer to winter. Lake-effect snow storms offer 36 inches of snow in one night, and summers with 30+ days of rain provide a climate of extremes. Make sure to pack appropriately. Nights are very cool here, even in the summer. In the winter, be prepared for below zero temperatures.
