What to expect on this route
Southbound · Great-circle bearing -147°
Most of the route sits away from the strongest jet-stream zones, so clear-air turbulence is less common than on long east-west crossings. A large portion of the flight crosses open ocean (North Pacific), where upper-level conditions are generally smoother than over continental terrain.
- Ocean / water segments
- North Pacific
Seasonal turbulence pattern
This corridor is most turbulent in the northern winter (Nov–Mar), when the jet stream is strongest and sits closer to the route.
- Peak turbulence
- November–March (Northern Hemisphere winter)
- Typically calmest
- Late spring to early autumn (May–September)
ICN → PVG turbulence FAQ
Is the Seoul to Shanghai flight usually bumpy?
Most of the 822 km route sits in the subtropical band with low jet-stream exposure. Historically that means most flights cruise in smooth air, with turbulence limited to short sectors near weather systems.
When is the best time to fly ICN to PVG for a smooth flight?
Statistically, Late spring to early autumn (May–September) sees the calmest conditions for this corridor. Within any season, morning departures see less convective (thunderstorm-driven) turbulence than afternoon flights.
How long is the flight from ICN to PVG?
Block time is usually around 1h 36m direct, cruising at approximately FL340 (34,000 ft). Actual duration varies with winds — tailwinds can shave 15–30 minutes, headwinds can add 30+ minutes on this southbound sector.
How accurate is Turbcast's forecast for this route?
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.
