What to Expect

The Fresno to Bentonville route is a journey across varied landscapes, each contributing its own unique weather quirks. Initially, you'll cross the Sierra Nevada where mountain wave turbulence, caused by wind flowing over the mountains, can create some chop. As you continue eastward, the flight path crosses the Mojave and Sonoran Deserts. Here, rising warm air, known as thermal turbulence, might cause a few bumps. Further along, the route encounters the Central Rockies and Front Range, where mountain wave turbulence can again be a factor. Finally, flying over the Great Plains, you might experience clear-air turbulence (CAT), which is often unexpected but usually mild. Depending on the time of year, you might also encounter severe convective turbulence related to storm activity in Tornado Alley and convective turbulence over the Ozark Plateau. Pilots are highly trained to navigate these conditions, using weather forecasts and radar to avoid the roughest patches, so there's no need to worry.

Flights between Fresno and Bentonville 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

• Mountain Wave Turbulence: The Sierra Nevada produces the well-known Sierra Wave, one of the strongest mountain wave systems in North America.
• Thermal Turbulence: Extreme desert heating generates strong thermal updrafts that cause low-to-mid-level turbulence, especially in summer afternoons.
• Clear-Air Turbulence (CAT): The jet stream frequently meanders over the Great Plains, producing wind shear and clear-air turbulence at cruising altitudes.
• Severe Convective Turbulence: Tornado Alley supercells produce some of the most intense convective turbulence in North American aviation.

When Is This Route Bumpiest?

For the smoothest flight, aim for summer or early fall. During these times, thermal activity in the deserts is less intense, and the risk of severe convective turbulence in Tornado Alley diminishes. Winter can also be relatively smooth because the air is more stable. Spring, early spring, and early summer tend to be bumpier due to increased thermal activity and the higher likelihood of storms forming in Tornado Alley. Mountain wave turbulence can occur year-round but is often more pronounced during the cooler months when stronger winds blow across the mountains.

Tips for This Flight

For a potentially smoother ride, consider booking a morning flight, as thermal activity tends to build throughout the day. Any turbulence you do encounter on this route is likely to feel like driving on a road with some potholes or speed bumps; it’s usually more unsettling than dangerous. To help stay calm, choose a window seat over the wing, allowing you to see outside and feel more in control, and remember to stay hydrated. Focus on slow, deep breaths, knowing that the pilots are expertly managing the flight and constantly monitoring conditions for your safety and comfort.
