Westbound (usually into prevailing winds) · Great-circle bearing -73°
Jet-stream exposure on this corridor is significant. Long mid-latitude legs mean clear-air turbulence is the dominant source of bumps, typically encountered at cruise altitude. Westbound aircraft typically fly against the prevailing winds, adding flight time. Captains often pick altitudes that avoid the strongest headwinds, which can also mean picking cleaner-air altitudes.
The North Atlantic track sees its strongest jet-stream activity from November through February, when winds commonly exceed 150 kt and clear-air turbulence is more frequent.
Most of the 4,863 km route sits in the subpolar band with high jet-stream exposure. Historically that means occasional clear-air turbulence at cruise altitude is normal, especially in winter.
Statistically, May–September sees the calmest conditions for this corridor. Within any season, morning departures see less convective (thunderstorm-driven) turbulence than afternoon flights.
Block time is usually around 6h 09m direct, cruising at approximately FL390 (39,000 ft). Actual duration varies with winds — tailwinds can shave 15–30 minutes, headwinds can add 30+ minutes on this westbound sector.
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.
