Los Angeles to Spokane Turbulence Forecast

LAX → GEG · 946 miles · ~2h 24m

What to Expect

The Los Angeles to Spokane flight is relatively short, just over two hours heading north. A good portion of it involves crossing the Sierra Nevada mountains. These mountains can create what's known as mountain wave turbulence, especially when winds are strong. Think of it like a boat creating waves in water; the wind flows over the mountains and can create wave-like patterns in the air. Pilots are very familiar with this phenomenon and constantly monitor weather conditions and reports from other aircraft to anticipate and navigate these areas safely. It's a normal part of flying in mountainous regions, and air traffic control provides valuable information to help pilots choose the smoothest possible path. While bumps are possible, they're usually manageable and well within the capabilities of the aircraft and the expertise of the flight crew.

Flights between Los Angeles and Spokane 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.

When Is This Route Bumpiest?

For the smoothest possible ride, aim for summer or early fall. During these months, the atmospheric conditions are generally more stable, and strong winds over the Sierra Nevada are less frequent. Winter and spring tend to be bumpier times to fly this route. This is because stronger jet streams and more significant temperature differences can lead to increased wind speeds and mountain wave activity. While turbulence can occur at any time of year, it's statistically more likely during the colder months due to these weather patterns.

Tips for This Flight

If you're concerned about turbulence, consider booking a morning flight, as the atmosphere tends to be more settled earlier in the day. Any turbulence you might encounter on this route will probably feel like driving on a slightly bumpy, unpaved road, not usually anything severe. For added comfort, choose a seat over the wing, as this area of the plane experiences less motion. Staying well-hydrated and focusing on slow, deep breaths can also help you feel more relaxed. Remember that the pilots are highly trained professionals and are constantly working to ensure a safe and comfortable flight.
