Tbilisi International Airport lies in the temperate mid-latitudes at 41.67° N, 44.95° E, on Asia/Tbilisi time (UTC+4).
Tbilisi International Airport has 1 runway. The longest, 13R/31L, measures 9,843 ft by 147 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 concrete. It is lit for night operations.
Runway 13R/31L is aligned roughly south-east/north-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 south-east/north-west alignment, so a strong crosswind means a crosswind landing rather than a switch to another strip.
