Beirut Rafic Hariri International Airport lies in the temperate mid-latitudes at 33.82° N, 35.49° E, on Asia/Beirut time (UTC+3).
Beirut Rafic Hariri International Airport has 3 runways. The longest, 03/21, measures 12,467 ft by 148 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. Surfaces vary across the field (asphalt, concrete). All 3 are lit for night operations.
Runway 03/21 is aligned roughly north-east/south-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. With 3 runways across 3 different headings, crews can pick whichever best suits the wind.
The runways are not interchangeable. 17/35 is 10,663 ft against 03/21's 12,467 ft, a difference of 1,804 ft, so the shorter one generally takes regional traffic while the longer handles anything heavy.
