Weather Briefing
MVFRRMAF Butterworth Air Base is currently reporting marginal VFR (MVFR) conditions with few clouds at 2,400 feet and 8 km visibility.
Wind Analysis
Winds are from the east (80°) at 6 knots. Runway 36 is favored with a 1-knot headwind and 6-knot crosswind component.
Visibility & Ceiling
Visibility is 8 km, below VFR minimums in some airspace classifications. Check local requirements before departing VFR. No ceiling exists. Cloud layers reported: few at 2,400 ft.
Temperature & Moisture
Temperature is 27°C (81°F) with a dewpoint of 24°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. The narrow temperature-dewpoint spread creates risk of fog formation, particularly during evening and early morning hours.
This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.

About RMAF Butterworth Air Base
RMAF Butterworth Air Base is a military facility. Civilian access may be restricted or require Prior Permission (PPR). Pilots should consult the MY AIP for current access procedures and restrictions.
Overview
RMAF Butterworth Air Base is a military airport located in Butterworth, Malaysia, situated at an elevation of 11 feet MSL. The base serves as a critical strategic location for Royal Malaysian Air Force operations, positioned near the western coast of Peninsular Malaysia. Its single runway (18/36) extends 8,000 feet and is constructed with asphalt surface.
Flying Conditions
Weather conditions at Butterworth are predominantly favorable for visual flight, with 99.1% of observations supporting VFR or MVFR operations. Wind patterns are consistently from the northwest at an average of 5.9 knots, with maximum gusts reaching 18 knots. Temperatures remain stable, averaging 26.5°C with a range between 20°C and 34°C, providing consistent flying conditions throughout the year.
Notable Features
The airport's low elevation and coastal location contribute to generally stable atmospheric conditions. Runway 18/36 experiences highly favorable wind alignment, with 100% wind compatibility and an average crosswind of just 4.3 knots. Pilots can expect excellent visibility, with an average of 10 statute miles and no recorded instances of significant visibility restrictions.
Approach Considerations
September, December, and January represent the most consistently favorable months for flying, offering optimal meteorological conditions. The single runway's length and orientation provide flexibility for most aircraft operations, with minimal wind-related approach challenges. Pilots should anticipate northwest winds and plan approaches accordingly, taking advantage of the predictable wind patterns.
