Weather Briefing
VFRAntonio B. Won Pat International Airport is currently reporting visual flight rules (VFR) conditions with clear skies and 10 SM visibility.
Wind Analysis
Winds are from the north (360°) at 10 knots. Runway 06L/24R is favored with a 5-knot headwind and 9-knot crosswind component.
Visibility & Ceiling
Visibility is 10 SM. Skies are clear with unlimited ceiling.
Temperature & Moisture
Temperature is 28°C (82°F) with a dewpoint of 25°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. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Expected weather includes: Showers Rain. Winds are forecast to reach up to 20 knots during the period. There is a 30% probability of MVFR conditions with Showers Rain between 14:00Z and 20:00Z.
Pilot Recommendations
Conditions are favorable for visual flight. The narrow temperature-dewpoint spread creates risk of fog formation, particularly during evening and early morning hours. 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 Antonio B. Won Pat International Airport
Overview
Antonio B. Won Pat International Airport serves as the primary international gateway for Guam, located in Hagåtña. The airport is strategically positioned at 13.485000, 144.797282, with an elevation of 298 feet above mean sea level. As a large airport, it provides critical aviation infrastructure for the Pacific region, supporting both commercial and potential military aviation operations.
Flying Conditions
Guam's tropical maritime climate presents variable weather conditions for pilots, with potential for rapid atmospheric changes. The airport's significant runway length (12,015 ft and 10,014 ft) provides substantial operational flexibility across different meteorological scenarios. Pilots should anticipate potential tropical weather patterns typical to the Mariana Islands, including occasional convective activity and tropical maritime wind conditions.
Notable Features
The airport features two parallel asphalt runways (06L/24R and 06R/24L) with substantial length, enabling operations for wide-body aircraft and providing redundancy in runway selection. Its geographical position on Guam offers unique challenges related to Pacific island terrain, including potential wind shear and localized microclimatic variations. The 298 ft elevation suggests a relatively low-altitude airport environment with minimal terrain interference.
Approach Considerations
Runway orientation (06/24) suggests prevailing wind considerations from east-northeast to west-southwest directions. The extensive runway lengths provide multiple approach and departure options, with 12,015 ft and 10,014 ft offering significant margins for various aircraft performance envelopes. Pilots should prepare for potential oceanic approach dynamics typical of Pacific island airport environments.
