Weather Briefing

MVFR

Masset Airport is currently reporting marginal VFR (MVFR) conditions with overcast skies at 2,100 feet and 14 SM visibility. Note: This observation is 36 hours old and conditions may have changed.

Wind Analysis

Winds are calm, presenting no crosswind concerns for any runway.

Visibility & Ceiling

Visibility is 14 SM. The ceiling is 2100 feet AGL (overcast), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 13°C (55°F) with a dewpoint of 11°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely.

Pilot Recommendations

VFR pilots should exercise caution. Consider filing IFR if instrument rated, or postponing the flight if conditions are expected to deteriorate further. The narrow temperature-dewpoint spread creates risk of fog formation, particularly during evening and early morning hours.

This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.

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.
