What are the best weather apps for drone pilots before flying?
I want to start checking conditions more carefully before every flight. What weather apps do experienced pilots use, and what specific numbers should I be looking at — wind speed, gusts, visibility? Are there drone-specific apps, or do I just use a regular weather app?

There are several excellent drone-specific and general weather apps. Here is the complete toolkit:
Top Recommended Apps
1. UAV Forecast (Free / Premium)
The best single-app drone weather solution. Combines multiple weather data sources and calculates a composite "flyability" score — green, yellow, or red based on wind speed, gusts, visibility, cloud ceiling, humidity, and precipitation. Tells you in one glance whether the day is fly-worthy. Includes a drone-specific wind limit you can set based on your aircraft's rating.
2. Windy.com (Free)
The best tool for understanding wind visually. Animated streamlines show wind direction and intensity at any altitude up to the stratosphere. The altitude slider is crucial — you can compare ground wind to wind at 100m, 200m, 400m. Surface can be calm while altitude winds are strong. Essential for any flight above 50m.
3. MeteoBlue (Free web, Premium app)
Excellent hyper-local forecast with 3-day hourly resolution. The METEOGRAM chart shows wind, gusts, precipitation, cloud cover, and temperature across 72 hours at a glance — excellent for planning a shoot day.
What Numbers to Check
- Sustained wind: Keep below 70% of your drone's rated max
- Gusts: Gusts 5+ mph above sustained = extra caution. Gusts above your drone's max rating = no-fly
- Visibility: Minimum 3 statute miles for recreational flying
- Cloud ceiling: Stay 500 ft below clouds (FAA requirement)
- Precipitation: No flying in rain unless your drone is water-resistant
Safe Wind Guidelines by Drone Type
- Budget drones (Holy Stone, Potensic): max 15 mph sustained, 20 mph gusts
- DJI Mini series: max 22–27 mph sustained depending on model
- DJI Air 3 and above: max 27–33 mph

My professional pre-flight weather stack for paid shoots: UAV Forecast for overall assessment, Windy for wind at altitude, NOAA Aviation Weather for METAR/TAF at nearest airport if flying near controlled airspace. The METAR gives official observed conditions — actual visibility, ceiling, wind direction and speed — from a certified station. It is the most reliable data source for legal compliance documentation on commercial flights.

Wind speed guidelines for beginners: the single most common cause of lost or crashed drones for new pilots is flying in wind that exceeds the drone's capability. I use a conservative rule: if the forecast shows any gusts within 5 mph of my drone's rated maximum, I stay grounded. Weather forecasts underestimate peak gusts regularly. The gap between "forecast 20 mph" and "actual 25 mph gust" has cost people expensive drones.
Beginners should aim to fly in sustained winds under 10 mph until they have 10+ hours of stick time and can reliably manage unexpected directional gusts.

Windy.com altitude layers explained: the "Surface" layer shows 10m wind (standard anemometer height). Switch to 100m to see the wind your drone actually experiences at typical flying altitude — often significantly higher than surface. Mountain and coastal locations especially have dramatic wind shear where calm at ground level becomes 25+ mph at 100m. Always check the altitude layer you plan to fly at, not just the surface wind.

Beyond wind: two other weather factors pilots often ignore. First, high humidity above 85% can affect electronics and motors over extended flights — less critical for casual flying but worth noting for long commercial sessions. Second, barometric pressure changes rapidly with approaching fronts — if pressure is dropping fast, a storm is coming and conditions can deteriorate within an hour. The UAV Forecast app includes a pressure trend indicator that makes this easy to monitor.
