Weather Briefing
MVFRLondon Heathrow Airport is currently reporting marginal VFR (MVFR) conditions with broken clouds at 1,300 feet and 10 miles or greater visibility.
Wind Analysis
Winds are from the northeast (50°) at 7 knots. Runway 09L/27R is favored with a 5-knot headwind and 4-knot crosswind component.
Visibility & Ceiling
Visibility is unrestricted. The ceiling is 1300 feet AGL (broken), placing conditions in the MVFR category.
Temperature & Moisture
Temperature is 18°C (64°F) with a dewpoint of 15°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 30 hours. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. There is a 30% probability of MVFR conditions between 01:00Z and 07:00Z. There is a 40% probability of VFR conditions between 00:00Z and 06:00Z.
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 London Heathrow Airport
Overview
London Heathrow Airport serves as the United Kingdom's primary international aviation hub, located in western London at 83 feet mean sea level. As a large airport handling extensive international and domestic traffic, Heathrow operates two parallel asphalt runways capable of supporting heavy commercial aircraft operations. Its strategic location and substantial infrastructure make it a critical transportation gateway for the Greater London metropolitan area.
Flying Conditions
Weather conditions at Heathrow demonstrate significant variability, with Visual Flight Rules (VFR) prevailing 50.1% of the time and Marginal VFR conditions occurring 29.8% of observations. Temperature ranges from -5°C to 27°C with an average of 9.6°C, presenting potential seasonal operational considerations. Wind patterns are predominantly from the south at 180° with an average speed of 8.5 knots, and both runways maintain 100% favorable wind alignment.
Notable Features
Heathrow features two parallel runways (09L/27R and 09R/27L) measuring 12,799 feet and 12,001 feet respectively, providing substantial operational flexibility. The airport's low elevation of 83 feet MSL and geographic positioning near London contribute to relatively stable approach characteristics. Visibility averages 10 statute miles, with minimal occurrences of severely restricted visibility (fog present in only 1.6% of observations).
Approach Considerations
Pilots can expect consistently favorable wind conditions across both runways, with an average crosswind of 5.8 knots. September through November represent the most reliable months for Visual Flight Rules operations. The airport's wind profile and runway configuration offer predictable approach and departure environments, with both runways demonstrating equivalent wind alignment and crosswind characteristics.
