New Orleans to Anchorage Turbulence Forecast

MSY → ANC · 3,426 miles · ~7h 21m

What to Expect

The New Orleans to Anchorage route can be a mixed bag when it comes to turbulence. Shortly after leaving New Orleans, you'll be over the Gulf Coast and Mississippi Valley, areas prone to what's called convective turbulence. This is caused by warm, moist air rising and can feel like driving over speed bumps. As you continue northwest, you’ll cross the Ozark Plateau, another region where convective turbulence is common. Further along, you'll enter Tornado Alley, where severe convective turbulence is possible, especially during certain times of the year. Finally, as you approach the Great Plains, you might encounter clear-air turbulence (CAT), which, despite its name, can still cause some bumps. Pilots are very familiar with these patterns and use onboard radar, as well as reports from other aircraft, to navigate accordingly.

The New Orleans to Anchorage route passes along the Gulf Coast, where warm Gulf of Mexico moisture fuels towering cumulonimbus clouds, especially from late spring through early fall. These convective cells can produce sudden, sharp jolts of turbulence even outside visible storm clouds. Afternoon and evening departures are particularly affected.

Turbulence Factors on This Route

• Convective Turbulence: Warm Gulf moisture drives rapid thunderstorm development along the coast, creating intense updrafts and downdrafts.
• 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?

If you're looking for the smoothest possible flight, winter and early spring tend to be gentler, as the atmospheric conditions are generally more stable. Fall can also be a good choice. Summer and early summer, however, tend to be bumpier. This is primarily because the increased heat leads to more convective activity over the Gulf Coast, Mississippi Valley, Ozark Plateau, and especially Tornado Alley, increasing the likelihood of turbulence along those portions of the route.

Tips for This Flight

Booking your flight for a morning departure can often lead to a smoother ride, as the atmosphere tends to be more stable earlier in the day. The turbulence on this route, particularly the convective type, often feels like driving on a slightly bumpy road, though clear-air turbulence can be more sudden. To help stay comfortable, choose a seat over the wing, which tends to experience less motion. Remember to stay hydrated and focus on slow, steady breathing; you'll be in Anchorage before you know it.
