Salt Lake City to Houston Intercontinental Turbulence Forecast

SLC → IAH · 1,195 miles · ~2h 53m

What to Expect

Your Salt Lake City (SLC) to Houston Intercontinental (IAH) flight, heading southeast for nearly three hours and covering almost 1200 miles, crosses diverse geographical areas, which means some potential for bumps. Initially, you'll be over the Central Rockies and Front Range, where mountain wave turbulence can occur as wind flows over the mountains. Once you're over the Great Plains, you might encounter clear-air turbulence (CAT), caused by shifting air currents high in the atmosphere. Further along, as you approach Tornado Alley, convective turbulence from developing storm systems can be a factor, especially in certain seasons. Finally, nearing Houston over the Gulf Coast, convective turbulence from afternoon thunderstorms is possible. Pilots are very familiar with these patterns and use onboard radar, pilot reports, and forecasts to navigate for the smoothest possible flight.

Between Salt Lake City and Houston Intercontinental, 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

• 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.
• Severe Convective Turbulence: Tornado Alley supercells produce some of the most intense convective turbulence in North American aviation.

When Is This Route Bumpiest?

The smoothest flights on this route are usually during the late summer and fall. During this period, the atmospheric conditions over Tornado Alley and the Gulf Coast tend to be more stable, reducing the chances of convective turbulence. Winter and early spring tend to be bumpier due to stronger winds creating mountain wave turbulence over the Rockies and more frequent clear-air turbulence over the plains. Spring and early summer also see increased storm activity in Tornado Alley, which can lead to more convective turbulence as you approach Texas.

Tips for This Flight

For the calmest experience, aim for a morning flight, as afternoon thunderstorms along the Gulf Coast are less likely then. If you do experience turbulence, remember that it often feels like driving on a bumpy road; the plane is designed to handle it. To ease any anxiety, choose a seat over the wing, which tends to experience less motion, and focus on slow, deep breaths. This can help regulate your nervous system and make the flight more comfortable. Know that the crew are monitoring conditions and prepared to handle any situation.
