The Forecast

Go or No-go now, then the next 24 hours.

The verdict for now comes first, with the time left and what ends it. Under it, the next 24 hours of whatever limits your drone most, usually gusts at its height, against your own limit. Drag along the chart to read any hour.

Hour detail

Tap an hour to see what stops you.

Every hour opens to every factor against its limit, the one that decides it first: gusts, wind, the weather itself, rain chance, temperature, visibility and Kp.

Marginal means close.

From 80% of a wind, gust or rain limit an hour turns Marginal, so you see trouble coming. Start from a preset for your drone’s weight, then set every limit yourself.

Rotorcast's Hour detail for 13:00 to 14:00 on Wednesday 14 October: No-go, gusts 27 mph, your limit is 23.9 mph. Below it every factor against its limit: gusts No-go, wind Marginal at 16.7 mph against 17.9, condition partly cloudy, rain chance 20%, temperature 12°C, visibility 18 km and Kp 3.67, all Go.

Rotorcast's Edit drone screen for the Pocket quad, started from Under 250 g: max wind 17.9 mph and max gusts 23.9 mph, Marginal from 80% of a limit at 14.3 and 19.1 mph, a flying height of 60 metres, and the weather limits.

Wind at height

Wind where your drone is, not at 10 metres.

Forecasts give the wind 10 metres up. Rotorcast works out wind and gusts at the height you fly, for open ground, trees and houses or town, and says how it got the figure.

Estimated at 60 m from the 10 m forecast for open ground.

Pre-flight checklist

A checklist for each drone.

Tick your own checks on site: six to start with, and any of your own for each drone.

Airspace is yours to check.

The same screen opens NATS’s airspace map and the CAA’s Drone Code in your browser. Rotorcast doesn’t check airspace or whether a flight is legal.

Your next window, before you open the app.

With Plus, the Home Screen and Lock Screen widgets show when the Go window you’re in ends, or when the next one starts, at your primary spot, and move on hour by hour. At 07:00 a notification can name the day’s best Go window from then on, when there’s one of at least an hour.

And the rest

Spots, checklists, the dark, no signal.

Add a spot three ways.

Tap the map, search for a place or use your location, then say what the ground is like there: it changes the wind at your height.

Every checklist you run is kept.

Checklist history keeps each run you finish: the spot, the drone, the checks ticked and whether you opened NATS’s airspace map.

Night, from civil dusk to dawn.

Hours between civil dusk and civil dawn at the spot are Night, and never Go unless you change that for a drone.

No signal on the hill.

The last forecast stays readable offline, with how old it is; after a day, Rotorcast says it may be out of date.

Your spots and drones, as CSV.

Export your spots and drones, and your checklist runs, on every plan.

How it compares

Built around your drone’s limits.

Rotorcast beside UAV Forecast, Drone Forecast and Drone Buddy, the three drone weather apps with over 1,000 ratings in our UK App Store searches on 15 October 2026.

Questions

What people ask first.

Does Rotorcast tell me if I’m allowed to fly?

No. Go means the forecast is inside the limits you set for your drone. Rotorcast holds no airspace data and doesn’t check airspace or the law; its checklist opens the CAA’s Drone Code and NATS’s airspace map in your browser.

How does it work out the wind at my height?

Rotorcast treats Apple Weather’s wind and gusts as the standard 10-metre forecast and scales both to your drone’s flying height, from 10 to 120 metres, for the ground at the spot: open ground, trees and houses, or town. It’s an estimate, and Hour detail says how it was made.

Where does the weather come from?

From Apple Weather, and the Kp index from NOAA’s Space Weather Prediction Center.

Does it work offline?

It shows the last forecast it fetched, marked offline with how old it is. A new forecast needs the internet.

Do I need an account?

No. There’s no account, no analytics and no ads. Your spots and drones stay on your iPhone; a spot’s coordinates go to Apple Weather to fetch its forecast.

What do I get without paying?

One spot, one drone and the next 24 hours, with Kp, daylight and the checklist, and no time limit. Rotorcast Plus adds ten days, every spot and drone, the widgets and the 07:00 notification for £1.99 a month or £12.99 a year, and new subscribers get 7 days free.
