Is turbulence worse over the Pacific than the Atlantic?
Pacific routes are generally slightly rougher than Atlantic routes due to stronger and more variable jet streams. Flights to Japan and Korea frequently encounter moderate turbulence, especially in winter. Sydney and Melbourne routes see less jet stream turbulence but more convective activity.
When is turbulence worst over the Pacific?
Pacific turbulence peaks in winter (November–March) when the Pacific jet stream strengthens. Westbound flights (LAX→NRT) tend to be rougher than eastbound due to headwinds. The typhoon season (June–November) adds convective turbulence in the western Pacific.
Which Pacific routes are most turbulent?
LAX–ICN (Seoul), ORD–NRT (Tokyo), and JFK–NRT are among the most turbulent transpacific routes. Flights crossing the Kuroshio Current region near Japan frequently encounter wind shear. Sydney–LA is one of the longest and often bumpiest routes due to crossing the Tasman Sea.
How do pilots avoid turbulence over the Pacific?
Pilots use SIGMET alerts, pilot reports (PIREPs), and weather radar to avoid turbulence. On Pacific routes, altitude changes of 2,000–4,000 ft can make a significant difference. The app provides real-time PIREP data so you can see what other pilots are reporting.
