Honolulu to Myrtle Beach Turbulence Forecast

HNL → MYR · 4,805 miles · ~10h 7m

What to Expect

Flying from Honolulu to Myrtle Beach means crossing diverse landscapes, each with its own potential for turbulence. Initially, you'll encounter Oceanic Clear-Air Turbulence and Oceanic Convection over the open Pacific, which can create light, gentle rocking. As you approach the American Southwest, thermal turbulence rises from the Mojave and Sonoran Deserts. Further inland, the Southern Rockies can cause mountain wave turbulence, a series of gentle ups and downs as air flows over the peaks. Crossing the Great Plains, you might experience Clear-Air Turbulence (CAT). During certain times of the year, Tornado Alley could bring severe convective turbulence. Later in the flight, you'll pass over the Ozark Plateau, the Mississippi Valley, and the Southeast Interior, all prone to convective turbulence from rising warm air. Finally, the Southern Appalachians can generate mechanical turbulence as the wind interacts with the mountains. Pilots are very familiar with these patterns and actively monitor weather to navigate the smoothest possible path.

The Honolulu 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

• 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?

Spring and early summer typically offer the smoothest flights on this route. Fall also tends to be mild, particularly late fall, as weather systems stabilize across the continent. Winter, late summer, and early spring are often bumpier, with winter storms stirring up the Pacific and mountain wave turbulence over the Rockies. Summer heat fuels thermal turbulence over the deserts and convective turbulence across the eastern half of the country. Late winter and early spring can bring gusty conditions and leftover storm systems, creating potential turbulence.

Tips for This Flight

Opting for a morning flight often leads to a smoother experience, as the air tends to be calmer before the day heats up. Any turbulence you encounter on this route is most likely to feel like driving on a slightly bumpy road. To enhance your comfort, choose a seat over the wing, as it's the most stable part of the plane, and remember to stay hydrated; dehydration can worsen any feelings of anxiety. Focus on slow, deep breaths, in through your nose and out through your mouth, and trust that the pilots are skilled at navigating these conditions, prioritizing your safety and comfort throughout the journey.
