What to expect on departures
Computed from CCU's geography and climate
At tropical latitude the jet stream is rarely directly overhead, so clear-air turbulence is less of a routine concern from CCU. Convective weather closer to the surface is the dominant turbulence source instead. Kolkata's tropical climate means convective build-up is a year-round concern — afternoon and early-evening departures from CCU encounter the most cell activity. Morning slots and red-eye departures are typically the smoothest of the day.
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
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.

CCU turbulence FAQ
Is turbulence common on flights from CCU?
Netaji Subhash Chandra Bose International Airport is best described as a tropical convective airport. At tropical latitude the jet stream is rarely directly overhead, so clear-air turbulence is less of a routine concern from CCU.
When is turbulence worst for Kolkata 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 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.
