Turbulence on the SYD → HKG route

This is a short or low-latitude sector, so clear-air turbulence from upper-level jets is rare. 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. A large portion of the flight crosses open ocean (South Pacific), where upper-level conditions are generally smoother than over continental terrain.

Calmest season: Dry season. This corridor is most turbulent in the relevant hemisphere’s winter, when the jet stream is strongest and sits closer to the route. At tropical latitudes, convective (thunderstorm-driven) turbulence dominates during regional wet seasons and monsoon cycles, typically worst in the afternoon and evening.
