Drone Weather: When Is It Safe to Fly?

Weather grounds more flights than any geozone does. Too much wind, gusts, rain, cold or a solar storm can bring your drone down — or simply make the flight impossible. This page explains which numbers matter, where the limits of the common models are, and how to check the weather for your own launch site in about a minute.

The weather values that decide a drone flight

  • Wind and gusts: the number that matters most. Manufacturers state a maximum wind speed (DJI Mini 4 Pro: 10.7 m/s, Mavic 3: 12 m/s, Matrice 4T: 12 m/s). Judge by the gusts, not the average — and remember that wind at flight altitude is considerably stronger than at ground level.
  • Precipitation: most consumer drones have no IP rating at all. Rain, fog and drizzle are a no-go; only models rated IP43 or better (the Matrice 4TD, for instance) tolerate light rain.
  • Temperature: below 0 °C battery capacity drops sharply, above 40 °C the battery and electronics overheat. Bring batteries up to room temperature before take-off.
  • Visibility: you have to keep the drone in sight with your own eyes (VLOS). Haze, fog and a low cloud base cut your usable range drastically.
  • Kp index (solar storms): from Kp 5 upwards GPS becomes unreliable, and the drone may drift or drop into ATTI mode. The Kp index comes from NOAA and is the same worldwide.
  • Cloud base and twilight: night flights are defined by civil and astronomical twilight. The cloud base rarely matters at 120 m, but it matters a great deal for visibility.

Wind is not just wind: altitude makes the difference

Weather apps report wind at 10 m above ground. At 100 m it is often one and a half to two times as strong, and more than that in exposed terrain. That is why Hoverpoint shows a wind profile up to your planned altitude and compares it against the limit of the drone in your hangar — red means not today.

How to check drone weather with Hoverpoint

  1. Pick a location: GPS, an address or coordinates — in the app or in the browser weather check.
  2. Pick a drone: the limits (max wind, temperature, IP rating) come from the catalogue in your hangar.
  3. Read the traffic light: green, warning or no-go per day and per hour for wind, gusts, rain, temperature, Kp index and visibility — with a 72-hour forecast.
  4. See the rain coming: The German Weather Service rain radar on the map shows the last hour and the next 2 hours, and with Pro hourly up to 3 days ahead. So you can see whether a shower passes before take-off – in the app and in the airspace check in your browser.
  5. Use the sun position: plan the shot around golden hour, shadow direction and twilight.
  6. Turn on push: the weekend outlook on Thursday and daily warnings arrive as notifications once you enable them in the app.

Rules of thumb from experienced pilots

  • Never fly at the top of the range. Plan for 70–80 % of the manufacturer’s figure, because gusts and wind at altitude always add to it.
  • Fly out into the wind and come back with it — that way the battery lasts for the trip home.
  • At Kp 5 or above, or in fog, the drone stays on the ground no matter how good the light is.
  • Check again just before take-off. Forecasts change, especially on the coast and in the mountains.

Frequently asked questions about drone weather

How much wind can a drone fly in?

That is set by the manufacturer, not by law. DJI Mini models handle around 10.7 m/s (Beaufort 5), the Mavic 3 and Air 3 roughly 12 m/s. What matters are the gusts and the wind at altitude — Hoverpoint compares both against the limit of the drone in your hangar.

Can you fly a drone in the rain?

Only with models that carry an IP rating (IP43 or IP55, for example). Consumer drones without one are a no-go in rain, fog and drizzle; water in the motors and sensors causes failures.

What does the Kp index mean for drones?

The Kp index measures geomagnetic disturbance caused by solar activity. From Kp 5 upwards GPS reception suffers, and the drone can drift or lose its position data. Hoverpoint shows NOAA’s forecast directly in the weather check.

Is the weather check free?

Yes. The weather check with its traffic light, wind at altitude, sun position and Kp index is free in the app and in the browser. Extended alerts and the weekend forecast by push notification are part of Hoverpoint Pro.
