This is a short or low-latitude sector, so clear-air turbulence from upper-level jets is rare. The route crosses or passes near the Himalayas, which can generate mountain-wave turbulence downwind when upper-level winds are strong. At tropical latitudes, convective turbulence from thunderstorms is the main driver — pilots generally route around storm cells, but afternoon/evening flights encounter more build-up than morning departures.
Wind flowing over Himalayas can generate mountain-wave turbulence that extends hundreds of kilometres downwind — most pronounced in winter when upper-level winds are strongest. Tropical routes see more convective (thunderstorm-driven) turbulence during regional wet seasons and monsoon cycles, typically worst in the afternoon and evening.
Most of the 4,552 km route sits in the tropical band with minimal jet-stream exposure. Historically that means most flights cruise in smooth air, with turbulence limited to short sectors near weather systems. Mountain-wave effects near the Himalayas add short bumpy stretches when upper-level winds are strong.
Statistically, Dry season sees the calmest conditions for this corridor. Within any season, morning departures see less convective (thunderstorm-driven) turbulence than afternoon flights.
Block time is usually around 5h 48m direct, cruising at approximately FL390 (39,000 ft). Actual duration varies with winds — tailwinds can shave 15–30 minutes, headwinds can add 30+ minutes on this eastbound sector.
We use live NOAA Aviation Weather Center pilot reports (PIREPs), SIGMETs and AIRMETs, layered with physics-based Ellrod and Richardson-number calculations from Open-Meteo pressure-level wind and temperature data. If a source is unavailable for a waypoint we show an em dash rather than invent a value.
