About GDN
Major airport serving Gdansk, Poland.
- Climate
- Subpolar — long winters, short cool summers
What to expect on departures
Computed from GDN's geography and climate
The jet stream meanders across this latitude seasonally — GDN sees its strongest CAT exposure in December–February, when the polar jet pushes equatorward and routes intersect it more often. June-onwards departures climb into cleaner upper-level flow.
Climbout notes
Climbout is usually unremarkable — most turbulence on flights from Gdansk occurs at cruise rather than immediately after takeoff.
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.
- Peak turbulence
- November–February (strong jet)
- Typically calmest
- May–September

GDN turbulence FAQ
Is turbulence common on flights from GDN?
Gdańsk Lech Wałęsa Airport is best described as a high-latitude airport. The jet stream meanders across this latitude seasonally — GDN sees its strongest CAT exposure in December–February, when the polar jet pushes equatorward and routes intersect it more often.
When is turbulence worst for Gdansk 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.
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.
