El Paso to Anchorage Turbulence Forecast

What to Expect

Your flight from El Paso to Anchorage, heading northwest for about 6 hours, crosses some interesting terrain that can influence air conditions. Expect some bumps, particularly related to mountain wave turbulence as you fly over several ranges. First, you'll cross the Southern Rockies, then later the Central and Northern Rockies, and finally the Cascades nearer to Anchorage. Mountain wave turbulence happens when wind hits these mountain ranges and is forced upwards, creating waves in the atmosphere. You also will fly over the Mojave and Sonoran Deserts early in the flight where thermal turbulence, caused by rising warm air, can be present. Remember, pilots are very familiar with these patterns and constantly monitor conditions to ensure a safe and comfortable flight. Turbulence is a normal part of flying, especially over mountainous regions.

The El Paso to Anchorage 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 smoothest possible flight, aim for the summer, early fall, fall, or winter months. These seasons tend to be calmer over the mountainous terrain you'll be crossing. Late winter, spring, early spring, late fall, and fall can be a bit bumpier. Spring and fall often bring stronger winds that interact with the Rockies and Cascades, increasing mountain wave turbulence. The desert areas you cross early in the flight are also more prone to thermal turbulence in the warmer months.

Tips for This Flight

If you're concerned about turbulence, booking a morning flight tends to be your best bet. The air is often calmer before it heats up during the day, reducing thermal turbulence over the deserts and giving less energy to mountain wave turbulence. Any turbulence you experience on this route will likely feel like driving over a bumpy road for a few minutes. To help stay comfortable, choose a seat over the wing, as this area experiences less motion. Staying hydrated and practicing deep, even breathing can also help you feel more relaxed. Remember that the crew is there to support you, and they are trained to handle all flight conditions.
