El Paso to Spokane Turbulence Forecast

ELP → GEG · 1,240 miles · ~2h 59m

What to Expect

The El Paso to Spokane flight, heading northwest for about 1240 miles, crosses some interesting terrain that can cause bumps. Right after takeoff, you'll be over the Southern Rockies. These mountains can create what's called Mountain Wave Turbulence, where air flows over the peaks and creates waves, like in a river, leading to some chop. Then you'll cross the Mojave and Sonoran Deserts, where rising hot air can cause Thermal Turbulence, little jolts and dips, especially during the day. As you continue, you'll encounter the Central and Northern Rockies, so there's potential for more Mountain Wave Turbulence. Pilots are very familiar with these patterns, monitor weather conditions closely, and often adjust altitude slightly to find smoother air. It's all a normal part of flying over mountainous regions.

The El Paso to Spokane route passes over the Southern Rockies in New Mexico and southern Colorado. While somewhat lower than the peaks to the north, these mountains still produce notable mountain wave turbulence, particularly when strong southwesterly winds aloft align perpendicular to the ridgeline.

Turbulence Factors on This Route

• Mountain Wave Turbulence: The Southern Rockies produce lee waves when southwesterly upper-level winds flow across the terrain.
• 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 calmest flight, aim for summer, fall, or winter. These seasons tend to bring more stable air over the mountains. Early fall is especially nice. Late winter, spring, and late fall tend to be bumpier. This is because temperature differences are greater, leading to stronger winds aloft. Stronger winds interacting with the Rockies create more pronounced Mountain Wave Turbulence. Also, the desert heat in the warmer months can kick off more Thermal Turbulence on the early part of the flight.

Tips for This Flight

Opt for a morning flight if you can, as the air tends to be calmer before the day heats up. Any turbulence you might experience on this route will likely feel like driving on a road with small potholes, not usually anything dramatic. Choose a seat over the wing, as it's the most stable part of the plane. Remember to stay hydrated, as that can help with any anxiety. The flight crew is there to assist you, so don't hesitate to ask questions or let them know if you're feeling uneasy. You'll be in Spokane before you know it.
