Palm Springs to Myrtle Beach Turbulence Forecast

PSP → MYR · 2,146 miles · ~4h 48m

What to Expect

Palm Springs to Myrtle Beach is a long east-bound flight that crosses a variety of geographic features, which means you might experience different types of turbulence along the way. Right after takeoff you'll be crossing the Mojave and Sonoran Deserts, where you might feel some bumps from thermal turbulence, which is just warm air rising. As you continue east, you'll fly over the Southern Rockies, potentially encountering mountain wave turbulence; this is when air flows over the mountains, creating waves. Then comes the Great Plains, known for clear-air turbulence or CAT, which can be tricky because it's not visible. You'll also be flying near Tornado Alley, so convective turbulence caused by storms could be a factor, particularly in certain seasons. Later, expect possible convective turbulence over the Ozark Plateau and Mississippi Valley as well as the Southeast Interior. Finally, expect mechanical turbulence over the Southern Appalachians. Pilots are very familiar with these patterns and monitor them closely.

The Palm Springs 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

• 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.
• 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?

The winter season tends to offer the smoothest rides on this route overall, with late fall also generally being calm. In contrast, summer, late winter, and spring can be bumpier. The summer months, especially, are prone to convective turbulence due to thunderstorms forming over Tornado Alley, the Ozark Plateau, the Mississippi Valley, and the Southeast Interior. Spring and early summer can see more severe convective turbulence, while late winter may bring more mountain wave turbulence as air flows over the Southern Rockies. Early spring sees mechanical turbulence form over the Southern Appalachians.

Tips for This Flight

If possible, aim for a morning flight, as the air is often calmer earlier in the day before the ground heats up and creates thermal or convective activity. Any turbulence you encounter on this route is most likely to feel like driving on a road with potholes or hitting a few speed bumps. Choosing a seat over the wing can minimize the sensation of movement. Remember to stay hydrated, as dry air can heighten anxiety. Focus on slow, deep breaths, reminding yourself that the pilots are highly trained to handle all kinds of weather, and the plane is built to withstand it; you're in capable hands.
