Sacramento to Phoenix Turbulence Forecast

SMF → PHX · 646 miles · ~1h 48m

What to Expect

Your flight from Sacramento to Phoenix is a pretty common route, about an hour and 48 minutes heading southeast. What makes this path unique is that it crosses some interesting terrain that can create a few bumps. Right after takeoff, you'll be crossing the Sierra Nevada mountains, which can cause something called mountain wave turbulence, especially when there's a strong wind. This is essentially air bouncing over the mountains like water over rocks in a stream. Later on, as you approach Phoenix, you'll be flying over the Mojave and Sonoran Deserts. The desert heat can cause thermal turbulence, which feels like hitting a few small potholes in the sky. Pilots are very familiar with both these types of turbulence and monitor them closely, adjusting altitude or route as needed to find the smoothest air possible.

Flights between Sacramento and Phoenix cross the Sierra Nevada, a steep mountain barrier in eastern California. The Sierra generates some of the most intense rotor and wave turbulence in the world — the famous "Sierra Wave" can reach the stratosphere. East-side downdrafts are especially sharp, and flights into or out of Reno or the Central Valley often feel the effects.

Turbulence Factors on This Route

• Mountain Wave Turbulence: The Sierra Nevada produces the well-known Sierra Wave, one of the strongest mountain wave systems in North America.
• 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?

The smoothest rides on this route are often in the late summer and early fall, as well as during the winter. During these times, the air tends to be more stable. Spring and summer can be a bit more turbulent. Spring is windy season in the mountains, increasing the chances of mountain wave turbulence. Summer's heat builds those thermals over the deserts, so you might experience a few more bumps as you get closer to Phoenix. Remember that even in bumpier seasons, most flights are perfectly smooth.

Tips for This Flight

If you're concerned about turbulence, try booking a morning flight, as the air is generally calmer before the day heats up. Any turbulence you might encounter on this route will most likely feel like driving on a slightly bumpy road, nothing too dramatic. For extra comfort, choose a seat over the wing; this area tends to experience less motion. Stay hydrated, and remember that the flight crew is well-trained to handle all conditions and will keep you informed. You'll be in Phoenix before you know it.
