Beijing → Hong Kong Turbulence Forecast

FAQ

• Is turbulence dangerous?

  Modern aircraft are engineered to handle even the heaviest turbulence. Turbulence is uncomfortable, but not a structural threat. Pilots can change altitude or routing to find calmer air.

• Which times of day are smoothest?

  Early morning and night flights tend to be smoother — thermal currents from solar heating can cause mild bumps on afternoon departures.

• Why are there light bumps at cruise altitude?

  At cruise altitude (around 10-12 km), wind shear from the jet stream can produce brief clear-air turbulence. It usually lasts a few minutes; the pilot turns on the seatbelt sign, sometimes adjusts routing.

• How reliable is this forecast?

  The forecast is computed from Open-Meteo using NOAA + UK Met Office WAFS wind data — the same sources pilot dispatchers use. No weather forecast is 100%; treat this as direction, not a guarantee.

• How do pilots know about turbulence ahead of time?

  Before each flight, pilots get a wind map briefing, ICAO SIGMET (significant meteorological advisories), and pilot reports (PIREPs) from other aircraft. In flight, they stay in active contact with ATC and nearby aircraft.
