Punta Cana International Airport lies in the tropics at 18.57° N, 68.36° W, on America/Santo_Domingo 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.
Punta Cana International Airport has 2 runways. The longest, 08/26, measures 10,171 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. Both are 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. With 2 runways across 2 different headings, crews can pick whichever best suits the wind.
