Phoenix to Denver Turbulence Forecast

PHX → DEN · 601 miles · ~1h 42m

What to Expect

The Phoenix to Denver flight is interesting because it crosses several distinct geographic regions, each with its own turbulence signature. Right after takeoff, you'll be over the Mojave and Sonoran Deserts, where rising hot air creates what's called thermal turbulence, those familiar little bumps that feel a bit like driving on a slightly bumpy road. As you continue northeast, you'll encounter the Southern Rockies, then the Central Rockies, and finally the Front Range. These mountain ranges can generate mountain wave turbulence, which is caused by wind flowing over the mountains. Pilots are very familiar with these mountain waves and thermal patterns. They constantly monitor and adjust the flight path to find the smoothest ride possible, so you're in good hands.

The Phoenix to Denver 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.

When Is This Route Bumpiest?

The calmest time to fly from Phoenix to Denver is typically in winter. The air tends to be more stable, and thermal turbulence is less pronounced over the desert. Fall also tends to be a smoother period. Summer, late winter, spring, and early spring can be a bit bumpier. Summer heat increases thermal activity over the desert, and the changing weather patterns in late winter, spring, and early spring can amplify mountain wave turbulence as winds interact with the Rockies.

Tips for This Flight

Opt for a morning flight. The air is generally calmer before the day heats up, which minimizes thermal turbulence early in the flight. Any turbulence you might experience on this route is most likely to feel like driving over small potholes, a brief jolt rather than anything severe. Choosing a seat over the wing can offer a slightly more stable experience. Remember to stay hydrated and breathe deeply. Try to focus on something enjoyable, such as a book or movie, and trust that the pilots are skilled at navigating these common weather patterns.
