How Do You Check to See If It Is Safe to Fly Your Drone?

Tool – UAV Forecast

UAV Forecast is one of the best weather apps for beginners and experienced drone pilots. It is available as a webpage, Android app or iOS app. It is a great solution to see weather wise if it is safe to fly your drone.

  1. You can try it without downloading it by going to UAV Forecast at:
    or download the app and install it on your device: iOS OR Android.
  2. Enter the location of your flight and click Search, or click “Use my location” if you are intending to fly where you are standing.
  3. You will quickly find information for your location, such as below:

At 33 Feet (10 Meters)

The default settings for UAV Forecast is 20mph max for wind at 33 feet from the ground.

At 400 Feet (121.92 Meters)

We now are looking at the data at 400 feet.

It is safe to fly on this occasion at 33-400 feet (10-121.92 meters).

I wouldn’t be too concerned about the Est. Sats Locked (warning) as I haven’t found that to be very accurate and had no trouble locking on many satellites once I’m all set to fly my drone.
