The new airport sits 35km from central Istanbul on the European side, slightly inland and exposed to Black Sea weather systems. Winters (December–March) are cold (0–8°C) with fog, rain, and occasional snow. Snow on the exposed plateau is more likely than in the city. Ice on taxiways causes delays.
Summers are warm (25–32°C) with dry, reliable weather. Spring and fall bring heavy rain and strong northerly winds (Poyraz) that can affect smaller aircraft. Fog is the primary low-season disruption risk. The airport's elevated position makes it slightly windier than the Atatürk site it replaced.
