What to Expect

The Phoenix to Rochester flight, heading northeast for about four and a half hours, crosses a variety of geographic features that can contribute to turbulence. Expect some bumps early on, as you pass over the Mojave and Sonoran Deserts; thermal turbulence is common here. As you continue, you'll encounter the Southern Rockies; mountain wave turbulence is possible as the air interacts with the peaks. The Great Plains can bring clear-air turbulence (CAT), which can appear unexpectedly. Depending on the time of year, you might cross Tornado Alley, where severe convective turbulence is possible, followed by the Mississippi Valley, which also sees convective turbulence. Approaching Rochester, you'll fly over the Great Lakes; lake-effect turbulence can occur, and the Ohio Valley often experiences frontal turbulence. Finally, the Northern Appalachians can create mechanical turbulence. Pilots are trained to anticipate and navigate these conditions, and turbulence is considered a normal part of flying.

The Phoenix to Rochester 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 smoothest flights on this route are often found in winter and fall, with summer and early fall also generally calmer. Winter offers more stable air over much of the route, especially as the plains cool down. Summer, late winter, spring, winter, early spring, early summer, late fall, and early winter tend to be bumpier. These seasons see increased thermal activity over the deserts, stronger winds over the Rockies, and more convective activity in Tornado Alley and the Mississippi Valley. Lake-effect turbulence is more common near the Great Lakes in the late fall and winter, too.

Tips for This Flight

Booking your flight for the morning often provides a smoother ride, as thermal activity tends to increase as the day heats up, and this can trigger convective turbulence. If you do experience turbulence, it will likely feel like driving on a bumpy, unpaved road for a few minutes at a time. Staying well-hydrated can help you feel more comfortable; dehydration can heighten anxiety. Remember that the crew is experienced at handling these conditions, and try to settle back and trust their expertise.
