Cayenne - Félix Eboué Airport lies in the tropics at 4.82° N, 52.36° W, on America/Cayenne time (UTC-3). Tropical airports contend with heat and humidity, both of which thin the air and lengthen takeoff runs, and with convective storms that build fast in the afternoon.
Cayenne - Félix Eboué Airport has 1 runway. The longest, 08/26, measures 10,486 ft by 148 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 08/26 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.
