Burbank to Boise Turbulence Forecast

BUR → BOI · 657 miles · ~1h 49m

What to Expect

Your Burbank to Boise flight is interesting, turbulence-wise, because it crosses several distinct geographic areas known for specific types of air movement. Immediately after takeoff, you'll be heading north over the Sierra Nevada mountains, which can generate what's called mountain wave turbulence. This happens when strong winds flow over the mountains and create waves of air downstream. As you continue, you'll cross the Mojave and Sonoran Deserts, where thermal turbulence is common, especially during the day. This is simply warm air rising off the hot desert floor. Finally, as you approach Boise, you'll cross the Northern Rockies, another area prone to mountain wave effects. Pilots are very familiar with these patterns; they constantly monitor conditions and adjust altitude or route as needed to find the smoothest possible ride.

Flights between Burbank and Boise 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 most consistently smooth flights on this route are usually during the summer and early fall. The desert heat is less intense in early fall, reducing thermal turbulence. Winter can also be smooth, but it's more variable, with the potential for stronger mountain wave activity. Spring, late fall, and winter are generally the bumpiest times, as the temperature differences between the ground and upper atmosphere are greatest, creating more significant thermal lift in the deserts and stronger winds over the mountain ranges. These conditions amplify the effects of both thermal and mountain wave turbulence.

Tips for This Flight

If possible, try to book a morning flight, as thermal turbulence over the deserts tends to build throughout the day. Any turbulence you experience on this route will likely feel like driving over a bumpy road or a series of small potholes; it's usually more unsettling than genuinely rough. Staying well-hydrated can help you feel more comfortable, so bring a water bottle to sip throughout the flight. Remember that the pilots are highly trained to handle these conditions, and turbulence is a normal part of flying; they are constantly working to ensure a safe and comfortable journey.
