What to expect on this route
Southbound · Great-circle bearing 147°
Most of the route sits away from the strongest jet-stream zones, so clear-air turbulence is less common than on long east-west crossings. The route crosses or passes near the Andes, which can generate mountain-wave turbulence downwind when upper-level winds are strong.
- Mountain crossings
- Andes
- Ocean / water segments
- South Pacific · South Atlantic
Seasonal turbulence pattern
The oceanic track sees its strongest jet-stream activity in the southern winter (Jun–Aug), when winds aloft are fastest and clear-air turbulence is more frequent. This corridor is most turbulent in the southern winter (Jun–Aug), when the jet stream is strongest and sits closer to the route. Wind flowing over the Andes can generate mountain-wave turbulence that extends hundreds of kilometres downwind — most pronounced in the southern winter (Jun–Aug), when upper-level winds are strongest.
- Peak turbulence
- June–August (Southern Hemisphere winter)
- Typically calmest
- Late spring to early autumn (Nov–Mar)
LIM → EZE turbulence FAQ
Is the Lima to Buenos Aires flight usually bumpy?
Most of the 3,153 km route sits in the subtropical band with low jet-stream exposure. Historically that means most flights cruise in smooth air, with turbulence limited to short sectors near weather systems. Mountain-wave effects near the Andes add short bumpy stretches when upper-level winds are strong.
When is the best time to fly LIM to EZE for a smooth flight?
Statistically, Late spring to early autumn (Nov–Mar) sees the calmest conditions for this corridor. Within any season, morning departures see less convective (thunderstorm-driven) turbulence than afternoon flights.
How long is the flight from LIM to EZE?
Block time is usually around 4h 10m direct, cruising at approximately FL370 (37,000 ft). Actual duration varies with winds — tailwinds can shave 15–30 minutes, headwinds can add 30+ minutes on this southbound sector.
How accurate is Turbcast's forecast for this route?
We use live NOAA Aviation Weather Center pilot reports (PIREPs), SIGMETs and AIRMETs, layered with physics-based Ellrod and Richardson-number calculations 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 value.
