Palm Springs to Spokane Turbulence Forecast

PSP → GEG · 954 miles · ~2h 24m

What to Expect

Flying from Palm Springs (PSP) to Spokane (GEG) involves crossing some interesting terrain that can lead to a bit of bumpiness, especially early in the flight. The route heads north, immediately passing over the Mojave and Sonoran Deserts. The desert air heats up quickly, creating what's known as thermal turbulence. This is caused by columns of rising hot air meeting cooler air above. It's very common, and pilots are well-aware of it, planning their altitude and speed to minimize any discomfort. Think of it like driving over a few speed bumps; the plane might rock a little, but it's all perfectly normal. After the desert crossing, the air usually smooths out considerably as you move further north, making for a more peaceful second half of the flight.

The Palm Springs to Spokane route crosses the Mojave and Sonoran Deserts, where intense daytime surface heating creates strong thermal updrafts and mechanical turbulence at lower altitudes. While cruise-level turbulence is generally lighter than over mountain terrain, summer monsoon thunderstorms over the desert Southwest can build rapidly and produce sharp convective jolts.

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.

When Is This Route Bumpiest?

For the smoothest possible ride on this route, aim to fly during the winter or fall months. The cooler temperatures mean less of that thermal activity rising from the desert floor, resulting in calmer air. Summer tends to be the bumpiest time to fly from Palm Springs, as the intense heat of the Mojave and Sonoran Deserts creates stronger thermal updrafts. Spring can also experience some turbulence, but it's generally less pronounced than in the peak heat of summer.

Tips for This Flight

If you're concerned about turbulence, the best thing you can do is book a morning flight. The air tends to be calmer before the desert heat really kicks in later in the day. Any turbulence you do encounter on this route will likely feel like driving over small, uneven bumps in the road, not a dramatic or sudden drop. To enhance your comfort, choose a seat over the wing; this area of the plane experiences less motion. Staying well-hydrated can also help you feel more relaxed, and remember that deep, steady breaths can work wonders for calming any nerves. The pilots are constantly monitoring the weather and will always prioritize a safe and comfortable flight.
