Fort Lauderdale to Phoenix Turbulence Forecast

What to Expect

Your Fort Lauderdale to Phoenix flight, while a fairly long one at nearly 2000 miles, crosses some interesting geographical areas that can influence turbulence. Soon after takeoff, you'll be flying over the Gulf Coast, which, depending on the weather, can bring about what's called convective turbulence. This is caused by warm air rising and creating bumpy conditions. Later in the flight, as you approach Phoenix, you'll cross the Southern Rockies where mountain wave turbulence sometimes occurs, created as the wind flows over the mountains. Finally, the Mojave and Sonoran Deserts can generate thermal turbulence; this is due to the desert heat creating rising air. Pilots are very familiar with these patterns, and they use weather forecasts and onboard radar to navigate them effectively.

The Fort Lauderdale to Phoenix 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

• Convective Turbulence: Warm Gulf moisture drives rapid thunderstorm development along the coast, creating intense updrafts and downdrafts.
• Mountain Wave Turbulence: The Southern Rockies produce lee waves when southwesterly upper-level winds flow across the terrain.
• Thermal Turbulence: Extreme desert heating generates strong thermal updrafts that cause low-to-mid-level turbulence, especially in summer afternoons.

When Is This Route Bumpiest?

For the calmest flight, aim to travel in the winter or early spring. At these times, the convective activity over the Gulf Coast is generally lower, and the mountain wave turbulence over the Rockies is less frequent. The summer months can be a bit more turbulent, with increased convective activity along the Gulf Coast and thermal activity over the deserts. Late winter and spring can also sometimes bring more bumps as weather patterns shift, particularly around the Rockies.

Tips for This Flight

Opt for a morning flight; the air tends to be calmer before the day heats up. Any turbulence you might experience on this route is most likely to feel like driving on a slightly bumpy road or encountering a few potholes. Choosing a seat over the wing can minimize the sensation of movement. Remember to stay hydrated and breathe deeply, knowing that the pilots are expertly managing the flight, and soon you'll be touching down in Phoenix.
