Latest news, Jan 14, 2026: I've just updated BumpySkies to use a new, higher-resolution weather data source from our friends at NOAA. I expect everything to continue working as usual, but if something in your forecast doesn't look right, use the "Report an issue" button to let me know. Thanks!

BumpySkies: a turbulence forecaster for flights within and departing the United States

For best results, try it shortly before departure.

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