Oran Es-Sénia (Ahmed Ben Bella) International Airport lies in the temperate mid-latitudes at 35.62° N, 0.62° W, on Africa/Algiers time (UTC+1).
Oran Es-Sénia (Ahmed Ben Bella) International Airport has 2 runways. The longest, 07L/25R, measures 11,811 ft by 148 ft, which puts the field in the long-haul capable category: widebodies operate comfortably, though the very longest sectors may need a payload trade. Surfaces vary across the field (asphalt, concrete). Both are lit for night operations.
Runway 07L/25R 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. Every runway here shares that north-east/south-west alignment, so a strong crosswind means a crosswind landing rather than a switch to another strip.
The runways are not interchangeable. 07R/25L is 9,843 ft against 07L/25R's 11,811 ft, a difference of 1,968 ft, so the shorter one generally takes regional traffic while the longer handles anything heavy.
