Phoenix to New York LaGuardia Turbulence Forecast

What to Expect

Your flight from Phoenix to LaGuardia crosses a huge swath of the United States, meaning you might encounter several different kinds of turbulence along the way. Immediately after takeoff, you'll be flying over the Mojave and Sonoran Deserts, where thermal turbulence, caused by rising warm air, is common. As you continue northeast, you'll cross the Southern Rockies, so expect possible mountain wave turbulence as the wind interacts with the peaks. Further along, over the Great Plains, you might experience clear-air turbulence (CAT), which can occur even in seemingly clear skies. Depending on the time of year, you could encounter severe convective turbulence in Tornado Alley, or convective turbulence over the Mississippi Valley. As you near your destination, you'll fly over the Ohio Valley, where frontal turbulence can occur, then the Northern Appalachians, where mechanical turbulence is possible. Finally, near the Atlantic Seaboard, you might again encounter clear-air turbulence (CAT). Experienced pilots are constantly monitoring conditions and adjusting altitude to find the smoothest possible ride, and these are very common patterns, so they're prepared.

The Phoenix to New York LaGuardia 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?

Winter and early fall are often the smoothest times to fly this route. The air is generally more stable, reducing thermal and convective activity. Summer, late winter, and spring, including early spring and early summer, tend to be bumpier. This is because the deserts and plains are heating up, creating thermal updrafts. Spring can also bring increased storm activity over Tornado Alley and the Mississippi Valley, leading to more convective turbulence. Changes in air masses over the Ohio Valley can lead to frontal turbulence as well.

Tips for This Flight

Choosing a morning flight can often provide a smoother experience, as the atmosphere tends to be more stable earlier in the day. Any turbulence you encounter on this route will likely feel like driving on a road with potholes or gentle speed bumps. Staying well-hydrated can help you feel more comfortable, so drink plenty of water before and during your flight, and try some simple breathing exercises. Remember that turbulence is a normal part of flying, and the crew is well-trained to handle it. You've got this.
