Weather Briefing
VFRManassas Regional Airport/Harry P. Davis Field is currently reporting visual flight rules (VFR) conditions with clear skies and 10 SM visibility.
Wind Analysis
Winds are from the north (10°) at 6 knots. Runway 34 is favored with a 5-knot headwind and 3-knot crosswind component.
Visibility & Ceiling
Visibility is 10 SM. Skies are clear with unlimited ceiling.
Temperature & Moisture
Temperature is 19°C (66°F) with a dewpoint of 16°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.
Pilot Recommendations
Conditions are favorable for visual flight. 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 Manassas Regional Airport/Harry P. Davis Field
Overview
Manassas Regional Airport/Harry P. Davis Field serves the metropolitan Washington D.C. area as a strategic medium airport located in Prince William County, Virginia. Positioned at 192 feet above mean sea level, the airport provides critical general aviation infrastructure for the Northern Virginia region. Its two asphalt runways offer substantial operational flexibility for pilots navigating the busy mid-Atlantic airspace.
Flying Conditions
Weather conditions at Manassas demonstrate highly favorable VFR operations, with 76.9% of observations reporting visual flight rules. Seasonal temperature variations are significant, ranging from -13°C to 32°C, which pilots should carefully consider during preflight planning. Wind patterns are predominantly northerly at an average of 7.3 knots, with calm conditions occurring 33.1% of the time, making for generally stable flying environments.
Notable Features
The airport features two parallel runways: 16L/34R at 5,700 feet and 16R/34L at 3,702 feet, both constructed with asphalt surfaces. Both runways demonstrate 100% favorable wind alignments, with consistently low average crosswind conditions of 3.5 knots. The airport's elevation and geographic location provide relatively predictable meteorological conditions, particularly during autumn and winter months.
Approach Considerations
October, January, and November represent the most consistent VFR months for airport operations. Pilots can expect average visibility of 9.4 statute miles, with only 1.8% of observations reporting visibility below 3 statute miles. Fog occurs in just 2.3% of observations, suggesting generally clear approach conditions. Both runways offer reliable wind alignments, allowing flexible approach and departure options.
