Overview

Beaufort MCAS - Merritt Field serves as a military airfield located in Beaufort, South Carolina. As a medium airport with four runways ranging from 3,941 to 12,202 feet, the facility supports significant marine corps aviation operations at an elevation of 37 feet above mean sea level.

Flying Conditions

Pilots can expect predominantly VFR conditions 75% of the time, with only 15.3% of observations presenting marginal or instrument flight conditions. Wind patterns are consistently from the northeast at an average of 6.6 knots, with temperatures ranging from -6°C to 36°C. October, November, and September offer the most stable and favorable flying weather, characterized by high visibility and minimal meteorological restrictions.

Notable Features

The airport features four runways with different surface types: two paved with emergency (PEM) surfaces and two asphalt (ASP) surfaces. All runways demonstrate 100% favorable wind alignments, with modest average crosswind components between 3.7 and 4.6 knots. The low elevation and coastal location suggest minimal terrain challenges for approach and departure procedures.

Approach Considerations

With excellent wind coverage and multiple runway options, pilots have flexibility in selecting optimal approach paths. Runway 05/23 offers the longest surface at 12,202 feet, providing ample landing and takeoff space. Visibility averages 8 statute miles, though pilots should be prepared for occasional reduced visibility events, with 6.2% of observations showing less than 3 miles of visibility and 3% experiencing fog conditions.
