Turbulence on the LCY → JFK route

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.

Calmest season: Late spring to early autumn (May-September). The oceanic track sees its strongest jet-stream activity in the northern winter (Nov-Mar), when winds aloft are fastest and clear-air turbulence is more frequent.
