Trondheim Airport Værnes turbulence forecast
Trondheim, Norway
TRD (Trondheim, Norway) sits at 63.46°N, 10.92°E, 56 ft elevation — inland.
About TRD
Major airport serving Trondheim, Norway.
- Climate
- Subpolar — long winters, short cool summers
What to expect on departures
Computed from TRD's geography and climate
The jet stream meanders across this latitude seasonally — TRD 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 Trondheim 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

TRD turbulence FAQ
Is turbulence common on flights from TRD?
Trondheim Airport Værnes is best described as a high-latitude airport. The jet stream meanders across this latitude seasonally — TRD 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 Trondheim 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.
