Myrtle Beach to Des Moines Turbulence Forecast

MYR → DSM · 970 miles · ~2h 26m

What to Expect

Your flight from Myrtle Beach to Des Moines, heading northwest for about 2 hours and 26 minutes, will likely involve a variety of turbulence types. Initially, expect some mechanical turbulence as you cross the Southern Appalachians; this is caused by wind flowing over the mountains. Further along, as you fly over the Southeast Interior and later the Mississippi Valley, convective turbulence, caused by rising warm air, could lead to some bumps, particularly during warmer months. Finally, crossing the Ohio Valley might bring frontal turbulence, resulting from weather fronts colliding. Pilots are very familiar with these patterns and use onboard weather radar to navigate the safest and most comfortable path, making adjustments as needed.

The Myrtle Beach to Des Moines route passes over the Southern Appalachians, from Virginia through the Great Smokies and Blue Ridge. These mountains create moderate mechanical turbulence during strong wind events, and the complex terrain can channel air in unexpected ways. Convective activity over the ridges in summer adds an additional turbulence source.

Turbulence Factors on This Route

• Mechanical Turbulence: The Southern Appalachians produce terrain-induced chop, especially during strong wind events and summer convection over the ridgeline.
• Convective Turbulence: The warm, humid Southeast interior supports frequent thunderstorm development, particularly during afternoon hours.
• Frontal Turbulence: The Ohio Valley is a preferred storm track where frontal boundaries and embedded convection create turbulence year-round.

When Is This Route Bumpiest?

For the smoothest possible flight on this route, aim for fall, especially late fall or early fall. The air tends to be more stable during this time, reducing the likelihood of convective turbulence. Spring, as well as winter, can also be fairly smooth. Winter, summer, spring, and early summer tend to be bumpier due to increased convective activity and stronger weather systems. During those times, expect more frequent, though still manageable, encounters with turbulence as you cross different geographic regions.

Tips for This Flight

If possible, book your flight for early morning, as the air is generally calmer then and less prone to convective turbulence, which peaks in the afternoon. Any turbulence you experience will likely feel like driving on a slightly bumpy road, nothing too dramatic. Staying well-hydrated and choosing a seat over the wing can also help to minimize any perceived motion; deep, slow breathing exercises can also help you stay calm. Remember, the pilots are highly trained to handle these conditions, and your safety is their top priority.
