Announcing: Historic weather!
It's been a long time coming but we've finally added historic weather options to the site! Visit the tracks list and select [H] next to the track you want to view. From there you can select a past date to view density altitude, air density and grains. Check out our updated post on historical weather data.
Please note that we are still working out some bugs. Test it out and let us know if you encounter any issues.
