What to Expect

Flying from Memphis to Maui means crossing a wide variety of geographic features, each potentially contributing to bumps along the way. Expect possible convective turbulence over the Mississippi Valley, Southeast Interior, and Ozark Plateau, especially in warmer months, as rising warm air creates updrafts. As you head west over the Great Plains, you might encounter clear-air turbulence (CAT), a phenomenon that can occur even in seemingly clear skies. If flying near Tornado Alley, severe convective turbulence is possible. Crossing the Southern Rockies introduces the potential for mountain wave turbulence, caused by air flowing over the peaks. The Mojave and Sonoran Deserts can create thermal turbulence as the hot ground heats the air. Approaching the Pacific Coast, you might experience CAT again before the long stretch over the open ocean, where oceanic clear-air turbulence and oceanic convection are possible. Pilots are trained to anticipate and navigate these conditions, adjusting altitude and course as needed for a safe and comfortable flight.

The Memphis to Maui 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

• Convective Turbulence: The Mississippi Valley is a breeding ground for squall lines and mesoscale convective systems that produce widespread turbulence.
• Clear-Air Turbulence (CAT): The jet stream frequently meanders over the Great Plains, producing wind shear and clear-air turbulence at cruising altitudes.
• Mountain Wave Turbulence: The Southern Rockies produce lee waves when southwesterly upper-level winds flow across the terrain.
• Thermal Turbulence: Extreme desert heating generates strong thermal updrafts that cause low-to-mid-level turbulence, especially in summer afternoons.

When Is This Route Bumpiest?

The fall months, and especially late fall, offer the best chance for a smoother flight on this route. Winter can also be relatively calm, but you may experience bumps from CAT. Spring, early summer, and summer tend to be bumpier due to increased convective activity over the Mississippi Valley, Southeast Interior, and Ozark Plateau, along with possible severe convective turbulence in Tornado Alley. Late winter and early spring may also bring more turbulence. Mountain wave turbulence is most common in winter and early spring, while thermal turbulence over the deserts is most common in summer.

Tips for This Flight

Choosing an overnight flight often leads to a smoother experience, as atmospheric conditions tend to be more stable during the night. Any turbulence you encounter on this route will likely feel like driving on a bumpy, unpaved road, or perhaps similar to the sensation of mild chop on a boat. Staying well-hydrated can help you feel more comfortable throughout the flight, so remember to drink plenty of water. Remember that the pilots are well-prepared and constantly monitoring conditions, so try to relax and enjoy the journey.
