Des Moines to Houston Intercontinental Turbulence Forecast

DSM → IAH · 803 miles · ~2h 6m

What to Expect

Your flight from Des Moines to Houston will take you south over a few areas known for turbulence. Leaving Des Moines, you'll cross Tornado Alley, which, especially in spring and early summer, can generate severe convective turbulence; that's the kind caused by rapidly rising warm air. As you continue south, you'll fly over the Ozark Plateau, which can also experience convective turbulence as air rises over the hills, especially in warmer months. Finally, as you approach Houston and the Gulf Coast, expect potential convective turbulence related to the warm, moist air masses there. These are well-known weather patterns, and pilots are highly trained to navigate them, using onboard radar and reports from other aircraft to find the smoothest possible path. It's all a normal part of flying these routes.

Between Des Moines and Houston Intercontinental, the flight path crosses Tornado Alley, the region stretching from Texas through Oklahoma and Kansas where severe convective storms are most frequent in the U.S. Supercell thunderstorms in this region produce extreme updrafts and downdrafts, and flights are routinely deviated around these cells, especially in spring and early summer.

Turbulence Factors on This Route

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

When Is This Route Bumpiest?

For the calmest experience, aim to fly this route in the fall, winter, or early spring. During these months, the air tends to be more stable, reducing the likelihood of convective turbulence over Tornado Alley, the Ozarks, and the Gulf Coast. Spring and summer are typically bumpier; increased heat and moisture can lead to more frequent and intense convective activity as the ground heats the air above it, causing updrafts and downdrafts. This creates the turbulence you might feel during your flight.

Tips for This Flight

If you're concerned about turbulence, booking a morning flight may offer a slightly smoother ride, as the atmosphere tends to be more stable before the day heats up. The turbulence you might encounter on this route is usually like driving on a bumpy road, with some moderate jolts possible; it's unlikely to be anything alarming. To help stay relaxed, choose a seat over the wing; this section of the plane experiences less motion. Staying well-hydrated can also help you feel more comfortable. Remember, the pilots are highly skilled at navigating these conditions, and your safety is their top priority.
