Aristides Pereira International Airport lies in the tropics at 16.14° N, 22.89° W, on Atlantic/Cape_Verde time (UTC-1). 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.
Aristides Pereira International Airport has 1 runway. The longest, 03/21, measures 6,890 ft by 148 ft, which puts the field in the narrowbody standard category: the A320 and 737 families are at home here; widebodies would be tight. The surface is asphalt. None of them carry runway lighting, which restricts operations to daylight and good visibility.
Runway 03/21 is aligned roughly north/south, 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/south alignment, so a strong crosswind means a crosswind landing rather than a switch to another strip.
