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 the winds of the ECMWF open global weather model. 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.
