Kuching International Airport lies in the tropics at 1.49° N, 110.35° E, on Asia/Kuching time (UTC+8). 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.
Kuching International Airport has 1 runway. The longest, 07/25, measures 12,402 ft by 151 ft, which puts the field in the full-length intercontinental category: a fully loaded Boeing 777 or Airbus A350 can depart for the far side of the world. The surface is asphalt. It is lit for night operations.
Runway 07/25 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.
