Maui to Greenville Turbulence Forecast

What to Expect

Flying from Maui (OGG) to Greenville (GSP) is quite an adventure, as you cross a wide range of terrains and weather systems. The first stretch involves crossing the open Pacific, where you might encounter oceanic clear-air turbulence or convection. As you approach the Pacific Coast, clear-air turbulence can occur. Moving inland, the Mojave and Sonoran Deserts can bring thermal turbulence, and the Southern Rockies introduce mountain wave turbulence. Over the Great Plains, more clear-air turbulence is possible, followed by a crossing of Tornado Alley, which can create severe convective turbulence. As you continue, the Ozark Plateau and Mississippi Valley may bring convective turbulence. The Southeast Interior can also have convective turbulence, while the final approach over the Southern Appalachians might involve mechanical turbulence. Keep in mind that pilots are trained to navigate these conditions, and turbulence is a normal part of flying.

The Maui to Greenville 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, winter, fall, and late fall are also typically more stable. However, winter, late summer, early spring, summer, late winter, spring, and early summer tend to be bumpier. This is because these seasons can amplify the effects of convection and temperature variations across the deserts, plains, and mountain ranges, leading to increased thermal, convective, and mountain wave turbulence. Seasonal weather patterns across Tornado Alley can also contribute to turbulence during certain times of the year.

Tips for This Flight

If possible, try to book a morning flight, as daytime heating often contributes to increased turbulence. Any turbulence you experience will likely feel like driving over a bumpy road, with some moderate chop that might make it a little harder to walk in the aisle. To stay comfortable, choose a seat over the wing, where movement is generally less noticeable, and remember to stay hydrated throughout your flight. Taking slow, deep breaths can also help you relax. Remember that the flight crew is there to ensure your safety and comfort, and turbulence is a routine part of their job.
