Minneapolis to Phoenix Turbulence Forecast

MSP → PHX · 1,275 miles · ~3h 3m

What to Expect

The Minneapolis to Phoenix route, heading southwest over 1275 miles, presents a variety of potential turbulence factors. Initially, the flight crosses the Upper Midwest and Great Plains, areas known for clear-air turbulence or CAT, which can occur even in cloudless skies due to shifting air currents. As you approach the Front Range and then cross the Central and Southern Rockies, mountain wave turbulence becomes a possibility. This type of turbulence happens when wind flows over mountainous terrain, creating waves in the atmosphere. Finally, approaching Phoenix, you'll encounter the Mojave and Sonoran Deserts, where thermal turbulence, caused by rising warm air, is common. Remember, pilots are trained to anticipate and navigate these conditions; it's all part of a routine flight.

Flights between Minneapolis and Phoenix pass along the Front Range, where the abrupt rise of the Colorado Rockies generates some of the strongest mountain wave turbulence in the continental U.S. Downdrafts east of the ridgeline can be intense, and rotor turbulence near the surface sometimes extends to cruising altitude during high-wind events.

Turbulence Factors on This Route

• Clear-Air Turbulence (CAT): The Upper Midwest sits beneath frequent polar jet stream intrusions, producing clear-air turbulence at cruising altitudes.
• Mountain Wave Turbulence: Strong westerly winds over the Front Range create oscillating waves that can produce sustained moderate turbulence at jet cruise levels.
• 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 smoothest possible ride on this route, aim for late summer or fall. During these seasons, thermal activity in the deserts is less intense, and the risk of mountain wave turbulence is generally lower. In contrast, late winter, spring, and early summer tend to be the bumpiest times to fly this route. Stronger winds across the Rockies increase the likelihood of mountain wave turbulence, and seasonal weather patterns can also contribute to more frequent clear-air turbulence.

Tips for This Flight

If you're concerned about turbulence, booking a morning flight is often your best bet, as the atmosphere tends to be more stable earlier in the day. Any turbulence you do experience on this route will likely feel like driving on a bumpy road or encountering strong gusts of wind. To stay comfortable, choose a seat over the wing, which is typically the most stable part of the plane, and focus on deep, steady breathing to help you relax. Remember that turbulence is a normal part of flying, and the crew is there to ensure your safety and comfort.
