Grand Bahama International Airport lies in the temperate mid-latitudes at 26.56° N, 78.70° W, on America/Nassau time (UTC-4).
Grand Bahama International Airport has 1 runway. The longest, 06/24, measures 11,019 ft by 151 ft, which puts the field in the long-haul capable category: widebodies operate comfortably, though the very longest sectors may need a payload trade. The surface is asphalt. It is lit for night operations.
Runway 06/24 is aligned roughly north-east/south-west, which is the clearest hint you get about the prevailing wind here: runways are built to face the wind that blows most often, because aircraft take off and land into it. Every runway here shares that north-east/south-west alignment, so a strong crosswind means a crosswind landing rather than a switch to another strip.
At 7 ft the field is effectively at sea level, which is the friendliest case for aircraft performance: maximum lift, maximum thrust and the shortest takeoff runs an aircraft is capable of.
