GYN to SDU Turbulence Forecast

Typical turbulence along the route

Historical average pattern for GYN–SDU

About the GYN–SDU route

The GYN to SDU route crosses the North Atlantic, where the jet stream is the primary source of turbulence. Flying at 35,000 feet, the aircraft encounters the strongest bumps roughly 2–5 hours into the flight. This is clear-air turbulence — no clouds, no visual warning — which makes a pre-flight forecast especially valuable.

The route is served by Gol, LATAM, Azul on Airbus A320 · Boeing 737 aircraft, with flights typically cruising at 35,000 feet over a distance of 713 miles (620 nautical miles).

💡 Tip: Turbulence peaks mid-flight over the Atlantic. First and last hour are usually smooth.
