What to Expect

That Phoenix to Honolulu route takes you over some diverse terrain, so let's talk about what that means for potential bumps. Right after takeoff from Phoenix, you'll be crossing the Mojave and Sonoran Deserts. The desert landscape heats up a lot, creating what's called thermal turbulence, kind of like the air shimmering above hot asphalt. Once you're over the vast Pacific, there are two other factors: clear-air turbulence (which can happen at higher altitudes) and oceanic convection. Oceanic convection is caused by warm, moist air rising off the ocean. All of this sounds intense, but remember airlines fly this route daily, and pilots are experts at managing these common weather patterns. They use onboard radar and reports from other planes to find the smoothest path possible.

The Phoenix to Honolulu route traverses the Open Pacific, where oceanic clear-air turbulence and convective activity over warm tropical waters are the primary concerns. Transpacific jet stream crossings can be especially bumpy in winter, and isolated convective cells over open water may not appear on standard weather radar used by dispatchers.

Turbulence Factors on This Route

• Thermal Turbulence: Extreme desert heating generates strong thermal updrafts that cause low-to-mid-level turbulence, especially in summer afternoons.
• Oceanic Clear-Air Turbulence: Transoceanic jet stream crossings produce extended stretches of clear-air turbulence over the open Pacific.
• Oceanic Convection: Isolated thunderstorms over warm Pacific waters can develop away from radar coverage, catching flights off guard.

When Is This Route Bumpiest?

For the calmest flight, aim for winter, fall, spring, or early summer. The air tends to be more stable during these times. Late summer, summer and winter can be a bit bumpier. The desert heat intensifies during the summer, making thermal turbulence more common as you leave Phoenix. Winter storms churn up the Pacific, and can also cause greater instability.

Tips for This Flight

If possible, morning flights tend to be smoother, before the desert air really heats up. Any turbulence you might experience on this route often feels like driving on a slightly bumpy road, or a brief roller coaster dip. Hydrate well before and during the flight to help combat any anxiety. A window seat over the wing can also offer a slightly more stable feel. With a little preparation, you can feel more in control and have a much more comfortable flight.
