Qantas QF136 flies the mountain-wave sensitive route from Christchurch to Sydney. Conditions change hour to hour — view the live forecast for your departure date.
View live forecastThe route crosses mid-latitudes where the polar jet can influence flight conditions, though exposure is shorter than on genuine long-haul crossings. The route crosses or passes near the Southern Alps, which can generate mountain-wave turbulence downwind when upper-level winds are strong. 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 and early autumn. Transpacific routes are most turbulent in winter months when the polar jet is strong and positioned further south. Wind flowing over Southern Alps can generate mountain-wave turbulence that extends hundreds of kilometres downwind — most pronounced in winter when upper-level winds are strongest.
