Weather Briefing

VFR

Noi Bai International Airport is currently reporting visual flight rules (VFR) conditions with scattered clouds at 4,300 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the west-northwest (300°) at 5 knots. Runway 29 is favored with a 5-knot headwind and 1-knot crosswind component.

Visibility & Ceiling

Visibility is unrestricted. No ceiling exists. Cloud layers reported: scattered at 4,300 ft.

Temperature & Moisture

Temperature is 36°C (97°F) with a dewpoint of 27°C, indicating moderate moisture conditions. High temperatures at this elevation may result in significant density altitude effects. Pilots should calculate density altitude and adjust performance expectations accordingly.

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: Thunderstorm Rain. There is a 40% probability of IFR conditions with Thunderstorm Rain between 09:00Z and 14:00Z.

Pilot Recommendations

Conditions are favorable for visual flight. 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.
