Des Moines to Austin Turbulence Forecast

DSM → AUS · 814 miles · ~2h 8m

What to Expect

The flight from Des Moines (DSM) to Austin (AUS) is a relatively short, two-hour hop south, but it does cross some interesting weather areas. Initially, you'll be flying through Tornado Alley, which can bring severe convective turbulence, especially during storm season. Further along, as you cross the Great Plains, expect the possibility of clear-air turbulence (CAT). This type of turbulence is caused by shifting air currents at higher altitudes, but pilots are very skilled at detecting and navigating around it. Finally, as you approach Austin and the Gulf Coast, there's potential for more convective turbulence, particularly if it's a warm, humid day, due to rising warm air. These are common, well-documented weather patterns that pilots are trained to handle, using radar and reports from other aircraft to ensure a safe and comfortable flight.

Between Des Moines and Austin, 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.
• Clear-Air Turbulence (CAT): The jet stream frequently meanders over the Great Plains, producing wind shear and clear-air turbulence at cruising altitudes.

When Is This Route Bumpiest?

The fall months generally offer the smoothest flights between Des Moines and Austin. The transition away from summer's heat and humidity reduces the likelihood of convective turbulence near the Gulf Coast and minimizes storm activity in Tornado Alley. Winter can also be relatively smooth, although early spring and summer tend to be bumpier due to increased storm activity and the conditions that cause convective turbulence along the Gulf Coast. The unstable air masses associated with these seasons make for a greater chance of turbulence.

Tips for This Flight

If you're concerned about turbulence, booking a morning flight from Des Moines may offer a slightly smoother experience. Any turbulence you encounter on this route will likely feel like driving on a bumpy road for a few minutes at a time, with the plane occasionally dipping or swaying. Choose a seat over the wing for a bit more stability. Remember to stay hydrated before and during the flight, as this can help minimize any feelings of unease, and focus on slow, deep breaths to stay relaxed. The crew is there to help and are well-prepared to manage any conditions you might encounter.
