Weather Briefing

MVFR

Boeing Field King County International Airport is currently reporting marginal VFR (MVFR) conditions with overcast skies at 1,600 feet and 10 SM visibility.

Wind Analysis

Winds are from the south-southwest (200°) at 8 knots with gusts to 17 knots. Runway 14L/32R is favored with a 4-knot headwind and 7-knot crosswind component (gusting to 15 knots crosswind).

Visibility & Ceiling

Visibility is 10 SM. The ceiling is 1600 feet AGL (overcast), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 12°C (54°F) with a dewpoint of 9°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.

Forecast Outlook

The TAF forecast covers the next 24 hours. The forecast shows a transition between VFR and IFR conditions. Pilots should monitor the forecast closely and have an alternate airport plan. Expected weather includes: Light Rain, Mist.

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. The forecast indicates conditions may deteriorate. Ensure you have fuel reserves and a viable alternate airport.

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

About Boeing Field King County International Airport

Overview

Boeing Field King County International Airport serves the Seattle metropolitan area as a critical medium-sized airport located at 47.529999, -122.302002. Situated at 21 feet mean sea level, the airport primarily supports general aviation, corporate, and limited commercial operations in the greater Seattle region. Its two paved runways (14L/32R at 3,709 ft and 14R/32L at 10,007 ft) provide significant operational flexibility.

Flying Conditions

Weather conditions at Boeing Field demonstrate moderate variability, with Visual Flight Rules (VFR) predominating at 64.9% of observations. Pilots can expect predominantly southerly winds averaging 6.6 knots, with occasional gusts up to 24 knots. Temperature ranges from -2°C to 33°C, creating diverse flying conditions throughout the year, with September, October, and December offering the most consistent VFR weather.

Notable Features

The airport features two parallel runways with nearly identical wind characteristics, both experiencing 100% favorable wind conditions and an average crosswind of 2.9 knots. Low-visibility events are relatively infrequent, with fog occurring in only 2.8% of observations and visibility dropping below 3 statute miles in just 2.6% of recorded periods. The longer runway (14R/32L) provides extended operational capabilities for larger aircraft.

Approach Considerations

Approach planning should consider the prevailing southerly wind pattern, which provides consistent wind alignment for both runways. With calm wind conditions present in 30.9% of observations, pilots should be prepared for variable wind scenarios. The airport's low elevation and consistent weather patterns generally support straightforward approach and landing procedures across both runways.
