Myrtle Beach to Seattle Turbulence Forecast

MYR → SEA · 2,430 miles · ~5h 22m

What to Expect

Your flight from Myrtle Beach to Seattle covers a significant distance, taking you across a wide variety of terrain, which means encountering different types of turbulence. Expect some bumps early on as you cross the Southern Appalachians; this is mechanical turbulence caused by wind interacting with the mountains. As you move further inland over the Southeast and later the Mississippi Valley, you might experience convective turbulence, which is caused by rising warm air. The Ohio Valley could bring frontal turbulence related to weather fronts. Once you're over the Great Plains, you could feel clear-air turbulence or CAT, which is often unexpected. Later, flying over the Northern Rockies and the Cascades, be prepared for mountain wave turbulence created by the wind flowing over the mountains. Finally, closer to Seattle along the Pacific Coast, you might encounter more CAT. Pilots are trained to handle these common weather patterns, using onboard radar and reports from other aircraft to navigate the smoothest possible path.

The Myrtle Beach to Seattle route crosses the Northern Rockies, a rugged expanse of high peaks in Montana, Idaho, and Wyoming. Mountain wave turbulence is frequent here, especially when Pacific storm systems push strong winds over the Continental Divide. Pilots often report moderate chop between 30,000 and 40,000 feet over this region.

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.
• Clear-Air Turbulence (CAT): The jet stream frequently meanders over the Great Plains, producing wind shear and clear-air turbulence at cruising altitudes.

When Is This Route Bumpiest?

For the calmest flight, aim to travel in the fall or winter. During these months, the atmospheric conditions are generally more stable over much of the route, reducing the likelihood of convective turbulence and strong frontal systems. Spring, early summer, early spring, late fall, and summer can be bumpier. During warmer months, you are more likely to encounter convective turbulence over the Southeast Interior and the Mississippi Valley due to increased heat and humidity. The mountainous regions are prone to mountain wave turbulence year-round, but it can be more pronounced during periods of strong winds, which are more common in the spring and fall.

Tips for This Flight

To potentially minimize turbulence, consider booking a morning flight. The earlier in the day you fly, the less time the sun has had to heat the ground and create convective currents. Any turbulence you experience on this route is most likely to feel like driving on a slightly bumpy road or a brief roller coaster dip. For extra comfort, choose a seat over the wing; this area tends to experience less motion. Staying well-hydrated can also help you feel more relaxed. Remember, the pilots are highly skilled at navigating these conditions, and the aircraft are designed to handle it, so try to settle in and enjoy the view.
