Latest news, Aug 29, 2026: I've fixed a bug that would display a "Proxy Error" message instead of a forecast for some longer flights, over the last week. Thanks to all who reported the issue! As always, if you encounter any errors or strange behavior with BumpySkies, let me know about it.

BumpySkies forecasts turbulence for flights within, departing, or arriving in the US. It was created by a nervous flier for other nervous fliers, making turbulence a little less surprising and scary.

For best results, try it shortly before departure.

(Or, see a random upcoming flight's forecast.)

Nelly the groundhog, nervous but brave, is ready to board her flight.
