HIGH Confidence
Your Journey Beta
A brief bumpy patch may occur during cruise. It's nothing to worry about - just keep your seatbelt fastened.
Your route takes you crossing the North Sea and crossing the Sea of Japan – these areas can sometimes cause light turbulence.
Smooth Flight
We're expecting smooth conditions throughout your flight. You can sit back and relax.
Takeoff
Takeoff should feel smooth, with calm conditions around the airport.
Winds Aloft
Winds at cruising altitude are about 36 knots. These winds are favorable and may get you there a few minutes early.
Landing
Landing should feel a bit bumpy on descent with typical approach conditions.
You're in Safe Hands
If you feel nervous at any point, remember that turbulence is expected, safe, and part of normal flying. The crew is monitoring everything, and the aircraft is built to handle far more than anything you will feel. Have a safe and calm flight.

🌤️ Afternoon Flight
Afternoon flights may encounter more turbulence due to thermal activity as the sun heats the ground, creating rising air currents.
Wide-Body Aircraft (Large)
Large, twin-aisle aircraft like this generally provide the smoothest ride through turbulence due to their size, weight, and advanced stabilization systems.

Data Sources & Our Approach
ZeroTurb's Custom Algorithm: We've developed a proprietary
ZeroTurb Index (ZTI) algorithm that combines three meteorological indices weighted by their
predictive accuracy. This gives you transparent, passenger-focused turbulence probability instead
of vague categories.
This forecast integrates data from:
- ECMWF Open Data - Global atmospheric model (wind/temperature at 13 flight levels)
- NOAA Aviation Weather Center - Pilot Reports (PIREPs), SIGMETs/AIRMETs, TAFs
- NOAA Space Weather Prediction Center - Aurora forecasts for polar routes
- AviationStack API - Flight schedules and airline operational data
Disclaimer: This forecast is for informational purposes only. Always consult official aviation weather sources and follow ATC guidance.
How accurate are turbulence alerts? Alerts are based on updated forecast models and pilot reports, and can change as departure approaches.
