Weather Briefing

MVFR

Noi Bai International Airport is currently reporting marginal VFR (MVFR) conditions with overcast skies at 2,900 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the east (100°) at 12 knots. Runway 11L/29R is favored with a 12-knot headwind and 2-knot crosswind component.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 2900 feet AGL (overcast), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 29°C (84°F) with a dewpoint of 26°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: Heavy Thunderstorm Rain, Showers Rain. Temporary IFR conditions are forecast with Heavy Thunderstorm Rain between 18:00Z and 22:00Z. Temporary IFR conditions are forecast with Showers Rain between 00:00Z and 04:00Z.

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. 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 Noi Bai International Airport

Overview

Noi Bai International Airport serves as the primary international gateway for Hanoi, Vietnam, located in the Soc Son district. As a large airport with two concrete runways exceeding 10,000 feet, it supports significant commercial and international aviation operations. The airport sits at a low elevation of 39 feet mean sea level, providing generally stable approach conditions.

Flying Conditions

Weather statistics indicate highly favorable flying conditions, with 87.1% of observations supporting visual (VFR) or marginal visual (MVFR) flight rules. Temperatures range from 9°C to 35°C, with an average of 22.3°C, suggesting minimal thermal extreme challenges. The best VFR months are October, September, and November, offering optimal flying weather with consistent visibility averaging 10 statute miles.

Notable Features

The airport features two parallel runways oriented 11/29, with excellent wind alignment. Both runways demonstrate 100% favorable wind conditions and minimal average crosswind at 3.5 knots. Prevailing winds from the northeast (45 degrees) at an average of 5.6 knots support predictable and stable flight operations, with rare calm conditions (1.3% of observations).

Approach Considerations

Pilots can expect consistently favorable approach conditions with high visibility and minimal meteorological restrictions. Fog is extremely rare, occurring in only 0.4% of observations, and visibility below 3 statute miles is essentially non-existent. The parallel runway configuration provides operational flexibility, with both runways offering similar wind characteristics and approach potential.
