Antalya → London Turbulence Forecast

Antalya to London is about 2,911 km and usually takes around 4h in the air. The track it follows runs over the Anatolian plateau, the Mediterranean, the Balkans, Central Europe, the Alps, Western Europe, the North Sea, and the British Isles.

Air lifting over the Anatolian plateau and the Alps can raise brief, light ripples at cruise; crews know these spots well and the movement stays gentle. Over the Mediterranean, the North Sea, the Balkans, Central Europe, and Western Europe the air is usually calm and settled. Nearer the British Isles the weather turns more Atlantic and the ride can be livelier for short spells, still firmly within the routine. This track threads jet-stream latitudes, so in winter you may feel a few minutes of light, choppy air high up; summer usually rides calmer.

For most of a flight this length you are at a steady cruise above the weather, where the ride is smooth; the livelier moments, if any, are short.
