Kona to Bentonville Turbulence Forecast

KOA → XNA · 3,870 miles · ~8h 14m

What to Expect

Your flight from Kona (KOA) to Bentonville (XNA) covers almost 4000 miles, so it's likely you'll experience some turbulence. The first stretch over the open Pacific can bring oceanic clear-air turbulence, or even the bumpier oceanic convection. As you approach the Pacific Coast, be prepared for more clear-air turbulence. Crossing the Mojave and Sonoran Deserts, you might feel some thermal turbulence, caused by rising warm air. The Southern Rockies could mean mountain wave turbulence, while the Great Plains often brings clear-air turbulence again. Tornado Alley might give you some severe convective turbulence, and finally, approaching Bentonville across the Ozark Plateau, you might experience convective turbulence. All these types of turbulence are normal; your pilots are trained to handle them safely and efficiently.

The Kona to Bentonville route passes over the Southern Rockies in New Mexico and southern Colorado. While somewhat lower than the peaks to the north, these mountains still produce notable mountain wave turbulence, particularly when strong southwesterly winds aloft align perpendicular to the ridgeline.

Turbulence Factors on This Route

• Oceanic Clear-Air Turbulence: Transoceanic jet stream crossings produce extended stretches of clear-air turbulence over the open Pacific.
• Oceanic Convection: Isolated thunderstorms over warm Pacific waters can develop away from radar coverage, catching flights off guard.
• Thermal Turbulence: Extreme desert heating generates strong thermal updrafts that cause low-to-mid-level turbulence, especially in summer afternoons.
• Mountain Wave Turbulence: The Southern Rockies produce lee waves when southwesterly upper-level winds flow across the terrain.

When Is This Route Bumpiest?

For the smoothest possible flight, aim for spring, early summer, or summer. Early fall and fall can also be good, generally offering calmer conditions than other times of year. Winter and late summer into early spring tend to be the bumpiest times, especially across the Rockies and Tornado Alley. Winter can amplify clear-air turbulence across the Pacific and Great Plains too. Thermal turbulence is more common in the desert regions during summer months, which can extend into early fall.

Tips for This Flight

If possible, consider booking a morning flight; the air tends to be calmer then, especially across the desert and plains. Any turbulence you encounter will most likely feel like driving over a bumpy road or hitting a few potholes; it's usually more unsettling than dangerous. For extra comfort, choose a seat over the wing; it's the most stable part of the plane. Remember to stay hydrated and practice deep, slow breathing; you've got this.
