Phoenix to Salt Lake City Turbulence Forecast

PHX → SLC · 508 miles · ~1h 31m

What to Expect

The flight from Phoenix to Salt Lake City takes you north over some interesting terrain, which definitely influences the potential for turbulence. Initially, you'll be cruising over the Mojave and Sonoran Deserts, where thermal turbulence is common. Think of it as the air bubbling up from the hot desert floor, creating some bumps, much like the feeling of driving over small ripples in the road. Later, as you approach Salt Lake City, you'll be crossing the Central Rockies. This introduces the possibility of mountain wave turbulence, which happens when wind flows over the mountains and creates waves in the air. Again, this is a very normal phenomenon, and pilots are highly skilled at navigating these conditions; they use weather forecasts, radar, and reports from other pilots to avoid any significant chop.

Between Phoenix and Salt Lake City, the flight path crosses the Central Rockies of Colorado and Utah. This area is one of the most turbulence-prone zones in the U.S., with mountain wave activity reported on more than half of winter days. Waves can propagate far downstream, meaning turbulence may begin well before or after the visible peaks.

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 Central Rockies produce frequent, sometimes severe, mountain waves that can extend 100+ miles downstream.

When Is This Route Bumpiest?

The smoothest flights on this route tend to be in fall, summer, and winter. Winter is generally calm, but the mountains can cause disturbances. Summer might bring desert thermals, but they're typically manageable. In contrast, late winter and early spring are often the bumpiest times to fly this route. The combination of lingering winter weather patterns hitting the Rockies can lead to more pronounced mountain wave turbulence. Spring's transition also stirs up atmospheric instability over the deserts, increasing thermal activity, so keep an eye on forecasts during those months.

Tips for This Flight

If you're concerned about turbulence, booking a morning flight is your best bet, as the air tends to be calmer before the day heats up; this minimizes thermal turbulence over the desert portion of the trip. Any turbulence you do experience on this route will likely feel like driving on a slightly bumpy, unpaved road: a constant series of small jolts. To help stay comfortable, choose a seat over the wing, which is closest to the plane's center of gravity and experiences less motion. Remember to stay hydrated, and focus on slow, deep breaths to help manage any anxiety. Pilots are well-prepared to handle these conditions, and your safety is always their top priority.
