Weather Briefing

IFR

Noi Bai International Airport is currently reporting instrument flight rules (IFR) conditions with scattered clouds at 1,000 feet and 3.4 km visibility.

Wind Analysis

Winds are from the northeast (50°) at 7 knots. Runway 11L/29R is favored with a 4-knot headwind and 6-knot crosswind component.

Visibility & Ceiling

Visibility is reduced to 3.4 km. IFR conditions prevail and an instrument clearance is required for operations in controlled airspace. No ceiling exists. Cloud layers reported: scattered at 1,000 ft, few at 2,700 ft (CB). Caution: cumulonimbus (thunderstorm) clouds reported at 2,700 ft AGL, indicating convective activity in the area.

Temperature & Moisture

Temperature is 32°C (90°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, Heavy Thunderstorm Rain. Temporary IFR conditions are forecast with Thunderstorm Rain between 10:00Z and 15:00Z. Temporary IFR conditions are forecast with Heavy Thunderstorm Rain between 16:00Z and 21:00Z.

Pilot Recommendations

An instrument rating and IFR flight plan are required. Verify that destination and alternate approach minimums are above current and forecast conditions.

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.
