BumpySkies is a free online service that aims to demystify flight for all commercial air passengers.

BumpySkies uses current weather and flight data to forecast periods of turbulence along the path of major-carrier flights within or departing the continental United States. It operates under the notion that expecting these bumpy patches will make encountering them less surprising and scary for nervous fliers.

I plan to add more features to make flights even more transparent—and therefore pleasant—for all passengers. You can stay informed about BumpySkies‘ developments by subscribing to the BumpySkies newsletter.

How BumpySkies works

BumpySkies gets all its weather data from NOAA, and all its flight data from FAA. When you ask BumpySkies about an upcoming flight, it looks up how the plane‘s planned path corresponds with forecasted atmospheric turbulence, and then presents the results to you as both an image and text.

BumpySkies only looks at the next few hours of weather data, and knows about a flight‘s planned route only when its pilots file their plan with the FAA. Therefore, it works best to check shortly before boarding. In flights that offer on-board WiFi, you can check while in the air, too!

Frequently asked questions about BumpySkies

• If a forecast predicts turbulence, does that mean an unsafe flight?

  No, turbulence does not mean an unsafe flight. The unexpected motion of turbulence can be scary to experience, especially for nervous fliers, but it poses no threat at all to the aircraft. You are safe. For more information, see the Turbulence FAQ.

• Can BumpySkies work for areas outside of the continental United States?

  BumpySkies supports flights that depart from the continental U.S., southern Canada, or northern Mexico, providing forecasts for the portions of those flights that remain within the forecast coverage area.

  Unfortunately, BumpySkies cannot provide forecasts for flights arriving in the U.S. from overseas, as the FAA flight data does not include sufficient route information for these flights.

  I would like BumpySkies to support a much wider international range in the future. Subscribe to the free newsletter for updates about new BumpySkies features.

• Who pays for this?

  The United States government runs both of the organizations that publish the data BumpySkies uses (NOAA and FAA). This turns BumpySkies—and you, its users—into a passive beneficiary of American tax dollars, so there‘s that.

  The costs of development and hosting and such are otherwise paid for by this service‘s creator and maintainer. If you’d like to help out with that, see the next section!

• How can I help BumpySkies?

  First of all, if you like it, tell your friends about it! The more people use the service and offer me feedback about it, the better it gets.

  If you value the BumpySkies service and can afford to spare a few dollars to help cover its hosting costs and support its ongoing maintenance, please visit the project’s Patreon page, with my sincere gratitude.

  If you are an American citizen, you can help support the science and services that BumpySkies relies on by letting your elected representatives know that you support federally funded climate science. You may also wish to donate, if you can, to charitable organizations such as the Union of Concerned Scientists who help support and legally defend climate science.

• Who created this?

  BumpySkies was created and is maintained by me, Jason McIntosh. I love to visit new, far-away places, but I don't always love the act of getting there by plane, even though it‘s often the only sensible route. I created BumpySkies to make this necessary discomfort more tolerable and less weird and frightening. I hope that other people find value in it as well.
