Salt Lake City to San Francisco Turbulence Forecast

SLC → SFO · 598 miles · ~1h 42m

What to Expect

Your flight from Salt Lake City to San Francisco crosses some interesting terrain, which can bring a few bumps. Leaving Salt Lake, you'll be flying over the Central Rockies; this is where mountain wave turbulence can occur, as the wind interacts with the mountains. Later, you'll cross the Sierra Nevada, another mountain range that can create the same effect. As you approach San Francisco and the Pacific Coast, you might experience clear-air turbulence (CAT). CAT happens when bodies of air moving at different speeds meet at high altitude. Pilots are very familiar with these types of turbulence; they monitor weather patterns and use onboard radar to navigate accordingly. Remember, these are common occurrences, and pilots are trained to handle them safely and smoothly.

Between Salt Lake City and San Francisco, 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): Pacific jet streaks arriving onshore drive upper-level clear-air turbulence along the West Coast.

When Is This Route Bumpiest?

For the smoothest possible flight, aim to travel during the summer or early fall. These seasons tend to be calmer because the atmospheric conditions that cause mountain wave turbulence and clear-air turbulence are less frequent. Winter and early spring can be bumpier due to stronger winds interacting with the Central Rockies and Sierra Nevada ranges, creating more mountain wave turbulence. The increased temperature differences in spring can also lead to greater clear-air turbulence along the Pacific Coast.

Tips for This Flight

If you are concerned about turbulence, booking a morning flight is often your best bet; the air tends to be calmer earlier in the day. Any turbulence you encounter on this route will likely feel like driving over a series of potholes in the road; it's more of a nuisance than anything else. To help yourself feel more comfortable, choose a seat over the wing, where you'll feel less motion, and focus on slow, deep breaths to stay relaxed. Remember that the flight crew is there to support you, and turbulence is a normal part of flying. You've got this.
