What to expect on departures
Computed from BOD's geography and climate
Bordeaux sits squarely under the mid-latitude jet, north 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 December–February when the jet is at its strongest. The Pyrenees sit upwind of BOD 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 December–February winds at FL300 cross the Pyrenees at near-perpendicular angles. Warm-season convection (June–August) drives the dominant turbulence pattern from BOD — afternoon thunderstorm cells are routed around but their wake turbulence and gust fronts can still affect arrivals and departures. BOD'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
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.
Seasonal pattern
Winter (December–February) brings the strongest jet-stream activity — that's when long-haul departures most often log clear-air turbulence at cruise. Summer (June–August) is peak thunderstorm season — convective turbulence is the dominant warm-season risk. Mountain-wave activity near the Pyrenees peaks in the cold season when upper-level winds blow hardest across the range.

BOD turbulence FAQ
Is turbulence common on flights from BOD?
Bordeaux-Mérignac Airport is best described as a jet-stream + mountain-wave corridor. Bordeaux sits squarely under the mid-latitude jet, north of which most long-haul corridors run.
When is turbulence worst for Bordeaux flights?
Winter (December–February) brings the strongest jet-stream activity — that's when long-haul departures most often log clear-air turbulence at cruise. Peak turbulence window: November–February (strong jet). Typically calmest: May–September.
Does the terrain around Bordeaux affect turbulence?
Yes — the Pyrenees 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.
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.
