Faleolo International Airport lies in the tropics at 13.83° S, 172.01° W, on Pacific/Apia time (UTC+13). 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.
Faleolo International Airport has 1 runway. The longest, 08/26, measures 9,843 ft by 148 ft, which puts the field in the widebody capable category: twin-aisle aircraft can use it, and narrowbodies have length to spare. The surface is asphalt. It is lit for night operations.
Runway 08/26 is aligned roughly east/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 east/west alignment, so a strong crosswind means a crosswind landing rather than a switch to another strip.
