Queenstown International, New Zealand
ZQN (Queenstown International, New Zealand) sits at 45.02°S, 168.74°E, 1,171 ft elevation — coastal with the Southern Alps nearby.
Major airport serving Queenstown International, New Zealand.
Computed from ZQN's geography and climate
Queenstown International sits squarely under the mid-latitude-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. The Southern Alps sit upwind of ZQN on prevailing flow days, generating mountain-wave turbulence that can extend several hundred kilometres downwind at cruise level. The lee-wave risk is highest when June–August winds at FL300 cross the Southern Alps at near-perpendicular angles. Warm-season convection (December–February) drives the dominant turbulence pattern from ZQN — afternoon thunderstorm cells are routed around but their wake turbulence and gust fronts can still affect arrivals and departures. ZQN'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.
Standard Instrument Departures (SIDs) often route around terrain; on strong-wind days, low-level turbulence in the lee of the hills is common in the first few thousand feet.
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. Mountain-wave activity near the Southern Alps peaks in the cold season when upper-level winds blow hardest across the range.

Queenstown International Airport is best described as a jet-stream + mountain-wave corridor.

Mountain-wave activity near the Southern Alps peaks in the cold season when upper-level winds blow hardest across the range. Peak turbulence window: June–August (Southern Hemisphere winter jet). Typically calmest: November–February.
Yes — the Southern Alps lie close enough to generate mountain-wave turbulence on days with strong upper-level winds. These waves can propagate hundreds of kilometres downwind, so they sometimes affect cruise even after you've left the immediate area.
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.
