SDU to SLZ Turbulence Forecast

Typical turbulence along the route

Historical average pattern for SDU–SLZ

About the SDU–SLZ route

The SDU to SLZ route crosses the North Atlantic, where the jet stream is the primary source of turbulence. Flying at 37,000 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 37,000 feet over a distance of 1,749 miles (1,520 nautical miles).

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