Weather Briefing
MVFRAndersen Air Force Base is currently reporting marginal VFR (MVFR) conditions with overcast skies at 16,000 feet and 10 SM visibility.
Wind Analysis
Winds are from the north (350°) at 13 knots. Runway 06L/24R is favored with a 4-knot headwind and 12-knot crosswind component.
Visibility & Ceiling
Visibility is 10 SM. The ceiling is 1100 feet AGL (broken), placing conditions in the MVFR category.
Temperature & Moisture
Temperature is 30°C (86°F) with a dewpoint of 26°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 30 hours. IFR conditions are expected to persist or develop. An instrument rating and IFR flight plan are recommended. Expected weather includes: Light Showers Rain, Showers Rain. Winds are forecast to reach up to 20 knots during the period. Temporary IFR conditions are forecast with Light Showers Rain between 06:00Z and 10:00Z.
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 Andersen Air Force Base
Andersen Air Force Base is a military facility. Civilian access may be restricted or require Prior Permission (PPR). Pilots should consult the GU AIP for current access procedures and restrictions.
Overview
Andersen Air Force Base is a medium-sized airport located in Yigo, Guam, serving as a critical military aviation facility in the Pacific region. Situated at 627 feet above mean sea level with coordinates 13.584000, 144.929998, the base features two substantial parallel runways capable of handling large military and transport aircraft. Its strategic location in the western Pacific makes it a key operational and logistics hub for military aviation.
Flying Conditions
Weather conditions at Andersen AFB demonstrate predominantly favorable flying conditions, with 90.6% of observations supporting VFR or MVFR flight rules. The prevailing winds come from the east at an average of 11.1 knots, with temperatures consistently ranging between 23°C and 31°C. Pilots can expect excellent visibility averaging 9.5 statute miles, with minimal instances of restricted visibility or fog.
Notable Features
The airport features two parallel runways: 06L/24R at 10,558 feet and 06R/24L at 11,185 feet, both constructed with PEM (Possible Explanation Missing) surface. Both runways demonstrate 100% favorable wind alignment, with an average crosswind of just 4.5 knots. The consistent wind patterns and substantial runway lengths provide excellent operational flexibility for various aircraft types.
Approach Considerations
Optimal flying months are September, October, and December, offering the most consistent weather conditions. The east-prevailing winds at 90 degrees create predictable approach and departure scenarios for both runways. With calm conditions occurring only 1.8% of the time and maximum winds reaching 30 knots, pilots should anticipate generally stable approach conditions with minimal wind-related challenges.
