About Watertown International Airport

Overview

Watertown International Airport serves the northern New York region, situated at an elevation of 325 feet MSL near the Canadian border. As a medium-sized airport, it provides critical aviation infrastructure for the Watertown metropolitan area, supporting both general aviation and regional transportation needs.

Flying Conditions

Pilots can expect predominantly Visual Flight Rules (VFR) conditions, with 60% of observations reporting clear weather and an additional 29% in Marginal VFR. Temperature variations are significant, ranging from -26°C to 26°C, with an average of 2.4°C. Wind patterns are predominantly westerly at 270°, with an average speed of 8.7 knots and occasional gusts up to 29 knots.

Notable Features

The airport features two parallel asphalt runways (07/25 and 10/28), each 5,000 feet long, providing flexibility for different wind conditions. Both runways demonstrate 100% favorable wind alignment, with minimal average crosswind components of 4.4 and 5.2 knots respectively. The geographical location suggests potential for challenging winter flying conditions.

Approach Considerations

September through November offer the most consistent VFR conditions for approach and departure. Visibility averages 8.5 statute miles, with only 5.5% of observations reporting visibility below 3 miles. Pilots should be prepared for occasional fog (3.4% of observations) and be aware of the significant temperature range that could impact aircraft performance.
