What to expect on departures
Computed from AKL's geography and climate
Auckland sits squarely under the mid-latitude jet, south of which most long-haul corridors run. Clear-air turbulence (CAT) at cruise is the most common source of bumps on departures from here, especially during June–August when the jet is at its strongest. Warm-season convection (December–February) drives the dominant turbulence pattern from AKL — afternoon thunderstorm cells are routed around but their wake turbulence and gust fronts can still affect arrivals and departures. AKL's coastal position means departures often transit from the cool marine boundary layer into warmer continental air within minutes of takeoff — a brief but reliable bumpy transition on warm-season afternoons when the sea breeze is set up.
Climbout notes
Climbout typically transitions from cool marine air to warmer continental air — a brief bumpy layer near the boundary is normal on summer afternoons.
Turbulence conditions
Pacific weather systems can cause variable conditions. Trans-Tasman flights may encounter the "Roaring Forties" winds. Generally moderate turbulence.
Seasonal pattern
Southern Hemisphere winter (June–August) is when the subtropical jet strengthens, and that's when long-haul CAT is most likely. Southern summer (December–February) is the main convective window.
- Peak turbulence
- June–August (Southern Hemisphere winter jet)
- Typically calmest
- November–February

AKL turbulence FAQ
Is turbulence common on flights from AKL?
Auckland Airport is best described as a mid-latitude jet-exposed hub. Auckland sits squarely under the mid-latitude jet, south of which most long-haul corridors run.
When is turbulence worst for Auckland flights?
Southern Hemisphere winter (June–August) is when the subtropical jet strengthens, and that's when long-haul CAT is most likely. Peak turbulence window: June–August (Southern Hemisphere winter jet). Typically calmest: November–February.
How accurate are Turbcast forecasts?
We combine live NOAA Aviation Weather Center data (PIREPs, SIGMETs, AIRMETs) with physics-based Ellrod and Richardson-number calculations derived 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 number.
