About Masset Airport

Overview

Masset Airport serves the community of Masset on British Columbia's Haida Gwaii archipelago. Located at 54.027500, -132.125000 with an elevation of 25 ft MSL, this medium airport provides critical transportation infrastructure for a remote coastal region. The single runway 13/31 supports essential regional transportation and potential maritime support operations.

Flying Conditions

Weather at Masset Airport demonstrates significant variability, with visual flight rules (VFR) conditions predominating at 56.9% of observed periods. Prevailing southerly winds average 8.8 knots, with occasional gusts up to 29 knots. Temperature ranges from -5°C to 20°C, creating potential for challenging transitional weather, particularly during shoulder seasons.

Notable Features

The 5000-foot asphalt runway (13/31) is aligned to capitalize on prevailing wind patterns, with 100% favorable wind coverage. Coastal proximity and archipelago terrain likely introduce complex wind dynamics and potential localized weather phenomena. Pilots should anticipate potential visibility restrictions, with observations indicating 10.4% fog occurrence and 4.2% of periods experiencing visibility below 3 statute miles.

Approach Considerations

Runway 13/31 demonstrates favorable wind conditions with an average crosswind of only 4.4 knots. September, October, and January represent statistically the most consistently VFR months for operations. Pilots should prepare for potential rapid weather transitions typical of coastal British Columbia environments, maintaining heightened situational awareness during approach and landing.
