Bumpiness along the flight
Takeoff on the left, landing on the right. The higher the line, the bumpier the air the forecast expects at that moment.
Where, and why
The flight split into stretches: how bumpy each is forecast to be, and what causes it.
Cruise0m – 4h 1mSmooth
Nothing significant forecast here.
At cruise the air is thin and cold, and most of it is calm. The bumps up here come from the jet stream, a river of fast wind whose edges stir the air, or from waves set off by mountains far below. This forecast maps exactly where those edges sit.

Jet-stream wind shear
Where fast air slides over slower air, usually at the edge of the jet stream, the boundary ripples like a flag. It is the most common kind of turbulence and it never comes as a surprise: it is on the crew's charts, and they slow to a set turbulence speed and let the aircraft ride it out.

Thunderstorms near the route
Between 2h 52m and 4h 40m into the flight the forecast has a few thunderstorms, the nearest about 50 km from the planned line.
Storms and a calm ride line are not a contradiction. The line follows the planned track at cruise height, above most storm tops, and pilots never fly through a storm: the weather radar in the nose paints every one, and the rule is to give it at least 20 nautical miles (about 37 km) of room. What a storm usually costs you is a few minutes of detour, not bumps.
The ride line stays calm here because the route as planned keeps its distance from them.

The aircraft
What SU208 is flown with, and how it handles bumpy air.
BOEING 777-300ER
Bigger and heavier aircraft are moved less by the same patch of air, but every airliner is built for far more than turbulence produces.

What each level feels like
- Smooth
- Calm air. Nothing to notice beyond the hum of the engines.
- Light
- Gentle ripples and the odd dip. Drinks stay put, and walking to the toilet is fine.
- Moderate
- Distinct bumps. A drink might slosh and the belt sign comes on. Uncomfortable, and the aircraft is in full control throughout.
- Severe
- Strong jolts, and loose items can move. Rare, and the reason the belt sign exists: crews slow down and change altitude to get out of it.
How this forecast is made
The planned route is sampled from gate to gate at the altitude the aircraft flies, through 3 independent global weather models, and corrected with turbulence reports radioed in by pilots in the last few hours. Each new model run replaces the forecast; nothing here is a guess from the airline's history.
The independent weather models behind this forecast agree on this ride.
Planned route · timing and conditions may change.
Why the bumps are only bumps
Built for it.
Airliners are tested to loads far beyond anything turbulence produces; the wing flexing you can see is by design.
Seen in advance.
Your crew flies with forecasts like this one, live reports from other pilots and their own weather radar, and they change altitude to stay out of the bumpy air.
The belt is the whole story.
Turbulence injuries almost always involve someone standing or unbuckled. Seated with the belt on, it is a bumpy road and nothing more.
Questions about SU208
Will SU208 be bumpy?
For the flight on Mon 5 Oct: Mostly smooth. About 30 minutes of light bumps mid-flight. Barely moves your drink. The forecast is replaced with every new weather model run, so check back closer to departure.
How long is SU208?
About 8h 50m gate to gate from Moscow to Shanghai, a distance of about 6,851 km.
What time does SU208 leave?
SU208 usually departs Moscow at 20:00 local time and arrives in Shanghai at 09:50 local time. Times change; the app tracks the live schedule.
Is turbulence dangerous on SU208?
Turbulence is uncomfortable, not dangerous to the aircraft. Airliners are certified for loads far beyond anything turbulence produces, and crews plan around the bumpy patches with the same kind of forecast as this one. Injuries are almost always to people who were standing or unbuckled, so keep your seatbelt fastened whenever you're seated.
How accurate is this turbulence forecast?
It is a forecast, so it is best within a day or so of departure and improves with every model run. The bumpy patches it finds are usually in the right place, but their timing can shift by a few minutes and the crew may change altitude to avoid them, so the ride you get is often smoother than the forecast.
