Mexico City International Airport turbulence forecast
Mexico City, Mexico
MEX (Mexico City, Mexico) sits at 19.44°N, 99.07°W, 7,316 ft elevation — inland.
About MEX
Latin America's busiest airport by passenger traffic.
- Climate
- High-altitude — thinner air, large diurnal temperature swings
What to expect on departures
Computed from MEX's geography and climate
At 7,316 ft, MEX's elevation reduces climb performance compared with sea-level airports — afternoon thermals and mechanical turbulence in the first few thousand feet of climbout are felt for longer. At tropical latitude the jet stream is rarely directly overhead, so clear-air turbulence is less of a routine concern from MEX. Convective weather closer to the surface is the dominant turbulence source instead. Mexico City's tropical climate means convective build-up is a year-round concern — afternoon and early-evening departures from MEX encounter the most cell activity. Morning slots and red-eye departures are typically the smoothest of the day.
Climbout notes
Climbout is usually unremarkable — most turbulence on flights from Mexico City occurs at cruise rather than immediately after takeoff.
Turbulence conditions
High altitude (7,300 ft) affects density altitude. Mountain wave turbulence possible from surrounding ranges. Afternoon thunderstorms common in summer.
Seasonal pattern
Convective turbulence cycles with the local wet/dry season rather than a strict calendar month — check regional rainy-season dates for the most accurate risk window.
- Peak turbulence
- Regional wet season
- Typically calmest

MEX turbulence FAQ
Is turbulence common on flights from MEX?
Mexico City International Airport is best described as a tropical convective airport. At 7,316 ft, MEX's elevation reduces climb performance compared with sea-level airports — afternoon thermals and mechanical turbulence in the first few thousand feet of climbout are felt for longer.
When is turbulence worst for Mexico City flights?
Convective turbulence cycles with the local wet/dry season rather than a strict calendar month — check regional rainy-season dates for the most accurate risk window. Peak turbulence window: Regional wet season. Typically calmest: Regional dry season.
How does MEX's high elevation affect flights?
Sitting at 7,316 ft, density altitude is a genuine consideration — aircraft need longer takeoff rolls and climbout is shallower than at sea-level airports. That means more time in the lower atmosphere, where thermal and mechanical turbulence is most common, especially on warm summer afternoons.
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.
