Malta International Airport lies in the temperate mid-latitudes at 35.85° N, 14.49° E, on Europe/Malta time (UTC+2).
Malta International Airport has 2 runways. The longest, 13/31, measures 10,991 ft by 190 ft, which puts the field in the long-haul capable category: widebodies operate comfortably, though the very longest sectors may need a payload trade. The surface is asphalt. Both are lit for night operations.
Runway 13/31 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. With 2 runways across 2 different headings, crews can pick whichever best suits the wind.
The runways are not interchangeable. 05/23 is 7,785 ft against 13/31's 10,991 ft, a difference of 3,206 ft, so the shorter one generally takes regional traffic while the longer handles anything heavy.
