Weather Briefing
MVFRWattay International Airport is currently reporting marginal VFR (MVFR) conditions with broken clouds at 8,300 feet and 8 km visibility.
Wind Analysis
Winds are from the southwest (220°) at 2 knots.
Visibility & Ceiling
Visibility is 8 km, below VFR minimums in some airspace classifications. Check local requirements before departing VFR. The ceiling is 8300 feet AGL (broken), well above standard VFR minimums.
Temperature & Moisture
Temperature is 31°C (88°F) with a dewpoint of 25°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. Conditions are expected to remain MVFR throughout the forecast period.
Pilot Recommendations
VFR pilots should exercise caution. Consider filing IFR if instrument rated, or postponing the flight if conditions are expected to deteriorate further.
This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.

Located at 17.988300, 102.563004 with an elevation of 564 ft MSL, the airport provides critical aviation infrastructure for the region. Its single runway (13/31) spans 9,843 feet with an asphalt surface, accommodating various aircraft types.
Flying Conditions
Weather conditions at Wattay are predominantly Marginal VFR (MVFR), with 80.8% of observations in this category and only 18.6% pure VFR. Temperatures range from 10°C to 35°C with an average of 25.1°C. Wind patterns are consistent from the north (0°) at an average of 3.7 knots, with maximum gusts reaching 14 knots and calm conditions present 13.8% of the time.
