San Francisco to Syracuse Turbulence Forecast

SFO → SYR · 2,434 miles · ~5h 22m

What to Expect

This San Francisco to Syracuse route, heading northeast across the continent, does cross a variety of geographic features that can contribute to turbulence. Right after takeoff you might feel some clear-air turbulence (CAT) coming off the Pacific Coast. As you head inland, the flight path crosses the Sierra Nevada and then the Central Rockies where mountain wave turbulence is common, caused by wind flowing over the mountains. The Great Plains and Upper Midwest can bring more clear-air turbulence (CAT), but this is usually manageable. Near the end of the flight, crossing the Great Lakes, you might encounter lake-effect turbulence, and as you approach Syracuse, the Northern Appalachians could create mechanical turbulence. Finally, as you prepare for landing you might notice clear-air turbulence (CAT) from the Atlantic Seaboard. All of these forms of turbulence are constantly monitored and well understood by your flight crew, who are skilled at navigating these conditions.

Flights between San Francisco and Syracuse cross the Sierra Nevada, a steep mountain barrier in eastern California. The Sierra generates some of the most intense rotor and wave turbulence in the world — the famous "Sierra Wave" can reach the stratosphere. East-side downdrafts are especially sharp, and flights into or out of Reno or the Central Valley often feel the effects.

Turbulence Factors on This Route

• Clear-Air Turbulence (CAT): Pacific jet streaks arriving onshore drive upper-level clear-air turbulence along the West Coast.
• Mountain Wave Turbulence: The Sierra Nevada produces the well-known Sierra Wave, one of the strongest mountain wave systems in North America.
• Lake-Effect Turbulence: The Great Lakes produce lake-effect convection and low-level wind shear from land-water temperature contrasts.
• Mechanical Turbulence: The Northern Appalachians generate low-level mechanical turbulence during strong post-frontal northwest winds.

When Is This Route Bumpiest?

For the smoothest possible flight, aim to travel during the summer or early fall. These months generally see less dramatic weather patterns across the country, resulting in calmer flights. Winter, early spring, spring, late fall, and early winter, on the other hand, tend to be bumpier. This is because stronger jet streams create more clear-air turbulence (CAT) over the Pacific Coast, the Great Plains, the Upper Midwest, and the Atlantic Seaboard. Mountain wave turbulence over the Sierra Nevada and the Central Rockies is also more pronounced with stronger seasonal winds. Lake-effect turbulence is common near the Great Lakes in the colder months.

Tips for This Flight

Booking a morning flight tends to be your best bet, as the atmosphere is often more stable earlier in the day. Any turbulence you encounter on this route is most likely to feel like driving on a slightly bumpy road or a small boat gently rocking on the water, and will likely only last a few minutes. To help stay relaxed, choose a seat over the wing, which is the most stable part of the aircraft, and focus on slow, deep breaths throughout the flight. Remember that the pilots are highly trained to handle any turbulence, and their priority is always your safety and comfort.
