Latest news, Aug 3, 2026: I've been updating how BumpySkies treats airport elevations, forecasts climb and descent rates, and classifies turbulence intensity, all based on real-world guidance. More about it in the next newsletter. Until then, if anything seems off, please report an issue!

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.
