About Charleston International Airport
Overview
Charleston International Airport serves the Charleston metropolitan area in South Carolina, providing both commercial passenger and military aviation services. Located at an elevation of 46 feet MSL, the airport features two substantial runways capable of handling a wide range of aircraft operations. Its strategic coastal location makes it an important transportation hub for the southeastern United States.
Flying Conditions
Pilots can expect predominantly favorable flying conditions, with VFR conditions present 78.9% of the time. Temperature ranges from -6°C to 33°C, creating relatively stable operational environments throughout the year. Wind conditions are generally mild, with an average speed of 7.1 knots and a prevailing direction from the north, and calm conditions occurring 16.4% of the time.
Notable Features
The airport's two runways offer excellent operational flexibility, with Runway 15/33 providing an extended 9,001-foot concrete surface and Runway 03/21 offering a 7,004-foot asphalt runway. Both runways demonstrate 100% favorable wind alignment, with minimal average crosswind conditions (3.7kt for 03/21 and 4.8kt for 15/33). Visibility averages 9.3 statute miles, with limited instances of reduced visibility.
Approach Considerations
November, September, and January represent the best months for VFR operations, with consistently favorable weather conditions. Pilots should be aware of occasional reduced visibility, with fog present 4.9% of the time and visibility below 3 statute miles in 2.2% of observations. The airport's low elevation and coastal location suggest typical maritime meteorological influences that should be considered during flight planning.
