About Luis Munoz Marin International Airport
Overview
Luis Munoz Marin International Airport serves as the primary commercial airport for San Juan, Puerto Rico, and is a critical transportation hub for the Caribbean region. Located at 18.439400, -66.001801, the airport sits at a low elevation of 9 ft mean sea level, providing relatively straightforward terrain for aviation operations.
Flying Conditions
Being situated in the Caribbean, the airport experiences tropical maritime weather conditions with potential for rapid changes and occasional convective activity. Pilots should anticipate warm temperatures year-round and the potential for tropical weather systems, particularly during the Atlantic hurricane season from June through November.
Notable Features
The airport features two substantial runways: runway 08/26 with a length of 10,002 feet constructed of asphalt, and runway 10/28 with 8,016 feet of concrete surface. Its two-runway configuration provides operational flexibility for different wind conditions and aircraft types, supporting large commercial and cargo operations.
Approach Considerations
Runway 08/26, being the longer runway at 10,002 feet, typically serves as the primary runway for larger aircraft and international operations. The airport's low elevation and coastal location mean wind patterns can be variable, so pilots should be prepared to utilize either runway based on current meteorological conditions.
