Historical Weather Data
Updated April 23, 2021
We've gotten a few questions recently asking about historical weather data. We just added the option to view hourly weather including air density, density altitude, and grains for past dates!
- Visit the list of US Tracks or list of international tracks to find your track. If you don't see your track listed, let us know and we'll add it.
- Click on the [H] next to your track in order to view yesterday's weather.
- To select a different date, click in the field in the top right of the screen and select your date. Click submit.
- The new date will load displaying weather data for that track.
If you are viewing the current weather for your track, you can click the historical link on the more info line just below the wind direction entry. Keep in mind you can still enter your own weather data to get DA in our free calculator.
Hopefully this will help when looking for weather from past dates!
