Turbulence on the SIN → JFK route

The route crosses mid-latitudes where the polar jet can influence flight conditions, though exposure is shorter than on genuine long-haul crossings. A large portion of the flight crosses open ocean (Indian Ocean), where upper-level conditions are generally smoother than over continental terrain.

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.
