Argyle International Airport lies in the tropics at 13.16° N, 61.15° W, on America/St_Vincent 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.
Argyle International Airport has 1 runway. The longest, 04/22, measures 9,000 ft by 148 ft, which puts the field in the widebody capable category: twin-aisle aircraft can use it, and narrowbodies have length to spare. The surface is asphalt. It is lit for night operations.
