Saint-Pierre Pierrefonds Airport lies in the tropics at 21.32° S, 55.42° E, on Indian/Reunion time (UTC+4). 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.
Saint-Pierre Pierrefonds Airport has 1 runway. The longest, 15/33, measures 7,000 ft by 150 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. It is lit for night operations.
Runway 15/33 is aligned roughly south-east/north-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 south-east/north-west alignment, so a strong crosswind means a crosswind landing rather than a switch to another strip.
