Free drone weather API

UAV Meteo's data is available as plain JSON for your own apps, dashboards, scripts and flight-school tools. No key, no sign-up, CORS enabled — call it straight from a browser.

Fair use

• No key needed. Up to 30 requests per minute per IP. Responses are cached for a few minutes, so please cache on your side too.
• Credit the sources. Show the attribution text and link to uavmeteo.com.
• Upstream terms apply. Forecast data comes from Open-Meteo, whose free service is for non-commercial use — commercial projects need their own Open-Meteo subscription. Airport observations are public-domain US government data (NOAA Aviation Weather Center).
• No guarantee. Forecasts and ratings are a planning aid, not flight clearance. There is no uptime guarantee; v1 fields won't be removed or renamed without a new version.

GET /api/v1/conditions

Current drone-flying conditions for a point and a flight rating for the next six hours.

• Speeds in m/s, visibility in meters, temperature in °C, directions in degrees the wind blows from, times in UTC.
• flightStatus and ratings.* are good, caution, bad or unknown — the same engine as the dashboard. Space weather and air quality never rate worse than caution.
• Errors: 400 invalid_location, 400 invalid_profile, 429 rate_limited, 502 upstream_unavailable — always JSON with error and message.

GET /api/local-weather

The nearest airport weather observation (METAR, within 150 km, last 3 hours) next to the forecast for the same point, with a stronger / similar / weaker verdict on the wind and a check of how representative the station is. See the Local Weather tool.

curl "https://uavmeteo.com/api/local-weather?lat=40.71&lon=-74.00"

GET /api/rain-window

Raw 15-minute precipitation (mm) for the point and 24 points on rings 10, 25 and 50 km around it, about three hours ahead — points[], times[] (unix seconds, end of each 15-minute interval) and precipMm[point][slot]. The Drone Rain Radar turns it into arrival times and movement.
