Geography
Coastal — marine-influenced airmass

What to expect on departures

Computed from SOF's geography and climate

Sofia 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. Warm-season convection (June–August) drives the dominant turbulence pattern from SOF — afternoon thunderstorm cells are routed around but their wake turbulence and gust fronts can still affect arrivals and departures. SOF'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

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.

SOF turbulence FAQ

Is turbulence common on flights from SOF?

Sofia Airport is best described as a mid-latitude jet-exposed hub. Sofia sits squarely under the mid-latitude jet, north of which most long-haul corridors run.

When is turbulence worst for Sofia 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.
