Weather Briefing
MVFRWattay International Airport is currently reporting marginal VFR (MVFR) conditions with broken clouds at 5,000 feet and 6 km visibility.
Wind Analysis
Winds are from the north-northwest (340°) at 2 knots.
Visibility & Ceiling
Visibility is 6 km, below VFR minimums in some airspace classifications. Check local requirements before departing VFR. The ceiling is 5000 feet AGL (broken), well above standard VFR minimums.
Temperature & Moisture
Temperature is 26°C (79°F) with a dewpoint of 22°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. 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.
