Honiara International Airport lies in the tropics at 9.43° S, 160.05° E, on Pacific/Guadalcanal time (UTC+11). 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.
Honiara International Airport has 1 runway. The longest, 06/24, measures 7,218 ft by 148 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 06/24 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.
