Kona to Myrtle Beach Turbulence Forecast

KOA → MYR · 4,752 miles · ~10h 0m

What to Expect

This Kona to Myrtle Beach flight is quite the cross-country adventure, passing over a diverse range of geographical features, each with its own potential for turbulence. Initially, you'll be over the open Pacific, where oceanic clear-air turbulence and convection can cause some bumps. As you approach the continental US, you'll fly over the Mojave and Sonoran Deserts, where thermal turbulence from rising hot air is common. Further inland, crossing the Southern Rockies introduces the possibility of mountain wave turbulence. Then comes Tornado Alley, notorious for severe convective turbulence, followed by the Ozark Plateau and the Mississippi Valley, both prone to convective turbulence. The Southeast Interior brings more of the same, and finally, the Southern Appalachians can create mechanical turbulence as the air interacts with the mountains. Pilots are very familiar with these patterns and actively monitor and navigate to minimize any discomfort.

The Kona to Myrtle Beach 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?

The spring and early summer months tend to offer the smoothest rides on this route. Cooler temperatures generally mean less thermal and convective activity over land. Winter, fall, summer, and late fall are also good times to fly. By contrast, winter, late summer, summer, late winter, spring, and early summer can be more turbulent. This is because summer heat intensifies thermal turbulence over the deserts and convective turbulence across the Midwest and Southeast. Late winter and early spring can bring unsettled weather patterns and increased storm activity, especially near Tornado Alley.

Tips for This Flight

Consider booking a morning flight, as daytime heating often increases turbulence. Any turbulence you experience will likely feel like driving over a bumpy road or a sudden dip, not unlike a small rollercoaster. To enhance your comfort, choose a seat over the wing, where movement is often less noticeable. Remember to stay hydrated, and focus on slow, deep breaths; you've got this, and the flight crew is there to help you have a smooth trip.
