Burbank to Grand Rapids Turbulence Forecast

BUR → GRR · 1,859 miles · ~4h 13m

What to Expect

Flying from Burbank to Grand Rapids, you'll cross a diverse range of landscapes, each with its own potential for turbulence. Initially, you'll encounter the Mojave and Sonoran Deserts, where thermal turbulence, caused by rising warm air, can create some chop. As you head northeast, you'll fly over the Central Rockies and the Front Range, where mountain wave turbulence, created as wind flows over the mountains, is common. Once you pass the mountains, the Great Plains can bring clear-air turbulence, or CAT, which is often unexpected, but pilots are always watching for it. Finally, crossing the Great Lakes and approaching Grand Rapids, lake-effect turbulence can occur, especially when there's a significant temperature difference between the water and the air above. These are all normal weather patterns that pilots train for and manage daily.

Between Burbank and Grand Rapids, 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.
• Clear-Air Turbulence (CAT): The jet stream frequently meanders over the Great Plains, producing wind shear and clear-air turbulence at cruising altitudes.
• Lake-Effect Turbulence: The Great Lakes produce lake-effect convection and low-level wind shear from land-water temperature contrasts.

When Is This Route Bumpiest?

For the smoothest flight, winter is often your best bet, though fall and summer can also be relatively calm, especially early fall. Summer tends to be bumpier due to increased thermal activity over the deserts and plains. Early spring, late fall, and early winter can also bring more turbulence, particularly around the mountains where strong winds create mountain waves, and over the Great Lakes, which generate lake-effect turbulence as colder air moves over warmer water.

Tips for This Flight

If you're anxious about turbulence, aim for a morning flight, as the air tends to be calmer earlier in the day. Any turbulence you encounter on this route will likely feel like driving over a bumpy road, or the sensation of mild to moderate chop. Staying well-hydrated can help you feel more comfortable; bring a reusable water bottle and sip on it throughout the flight. Remember that turbulence is a normal part of flying, and the pilots are always prepared to handle it, keeping you safe.
