What to expect on departures
Computed from CWB's geography and climate
The 2,988 ft elevation puts CWB above most of the densest surface air, so initial climb is brisk but the airport itself sits inside any low-level turbulence patterns. The jet stream meanders across this latitude seasonally — CWB sees its strongest CAT exposure in June–August, when the polar jet pushes equatorward and routes intersect it more often. December-onwards departures climb into cleaner upper-level flow. Monsoon months pump moisture and instability into the local airmass — expect significantly more convective turbulence during the wet season at CWB, with much smoother cruise during dry-season operations. CWB'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
Climbout typically transitions from cool marine air to warmer continental air — a brief bumpy layer near the boundary is normal on summer afternoons.
Seasonal pattern
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.
- Peak turbulence
- Monsoon months (varies by hemisphere)
- Typically calmest
- Dry season

CWB turbulence FAQ
Is turbulence common on flights from CWB?
Afonso Pena Airport is best described as a standard profile airport. The 2,988 ft elevation puts CWB above most of the densest surface air, so initial climb is brisk but the airport itself sits inside any low-level turbulence patterns.
When is turbulence worst for Curitiba flights?
Southern Hemisphere winter (June–August) is when the subtropical jet strengthens, and that's when long-haul CAT is most likely. Peak turbulence window: Monsoon months (varies by hemisphere). Typically calmest: Dry season.
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.
