What to expect on departures
Computed from SVQ's geography and climate
Sevilla 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 Atlas Mountains sit upwind of SVQ 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 Atlas Mountains at near-perpendicular angles. Warm-season convection (June–August) drives the dominant turbulence pattern from SVQ — afternoon thunderstorm cells are routed around but their wake turbulence and gust fronts can still affect arrivals and departures. SVQ'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 Atlas Mountains peaks in the cold season when upper-level winds blow hardest across the range.
- Peak turbulence
- November–February (strong jet)
- Typically calmest

SVQ turbulence FAQ
Is turbulence common on flights from SVQ?
Sevilla Airport is best described as a jet-stream + mountain-wave corridor. Sevilla sits squarely under the mid-latitude jet, north of which most long-haul corridors run.
When is turbulence worst for Sevilla 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 Sevilla affect turbulence?
Yes — the Atlas Mountains 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.
