U-Tapao–Rayong–Pattaya International Airport lies in the tropics at 12.68° N, 101.00° E, on Asia/Bangkok time (UTC+7). 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.
U-Tapao–Rayong–Pattaya International Airport has 1 runway. The longest, 18/36, measures 11,500 ft by 197 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 18/36 is aligned roughly south/north, 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/north alignment, so a strong crosswind means a crosswind landing rather than a switch to another strip.
