Weather Briefing

MVFR

Mae Hong Son Airport is currently reporting marginal VFR (MVFR) conditions with broken clouds at 2,500 feet and 10 miles or greater visibility. Note: This observation is 10.9 hours old and conditions may have changed.

Wind Analysis

Winds are calm, presenting no crosswind concerns for any runway.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 2500 feet AGL (broken), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 31°C (88°F) with a dewpoint of 23°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. Temporary IFR conditions are forecast with Thunderstorm Rain between 18:00Z and 03:00Z. Temporary IFR conditions are forecast with Thunderstorm Rain between 08:00Z and 18:00Z.

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 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 Mae Hong Son Airport

Overview

Mae Hong Son Airport serves the mountainous northern Thailand region, situated at an elevation of 929 feet MSL in a remote provincial area. Located at coordinates 19.301300, 97.975800, this medium-sized airport provides critical aviation infrastructure for Mae Hong Son Province. The airport supports regional transportation with a single runway 11/29 measuring 6562 feet in asphalted surface.

Flying Conditions

Weather observations indicate predominantly favorable VFR conditions, with 61.2% of recorded periods supporting visual flight rules. Seasonal temperatures range from 12°C to 35°C, averaging 25.8°C, with the most stable flying conditions occurring in October, January, and December. Wind patterns are consistently southeast at 135°, averaging 4 knots with occasional peaks to 14 knots, and experiencing calm conditions 18.3% of the time.

Notable Features

The airport's mountainous geographical context suggests complex terrain considerations for pilots. Surrounded by elevated landscape, approach and departure paths likely require careful navigation and terrain awareness. The airport's moderate elevation and single runway configuration demand precision and adherence to established procedures.

Approach Considerations

Runway 11/29 demonstrates highly favorable wind alignment, with 100% wind compatibility and minimal average crosswind of 1.9 knots. Pilots can expect generally predictable approach conditions, particularly during peak VFR months. Low probability of significant visibility restrictions (0% below 3SM) supports consistent operational reliability.
