Drone Weather - Weather4Fly

Weather4Fly is a weather intelligence app built specifically for drone pilots. It helps turn detailed weather data into a clear preflight decision: Safe to Fly, Caution, or No Fly.

Version 3.0 is a major update with a rebuilt decision engine, redesigned Hourly and Forecast screens, Apple Watch support, smarter daily briefings, and clearer flight assessment details.

DRONE-SPECIFIC SAFETY ASSESSMENTS

Weather4Fly evaluates the conditions that matter before takeoff: wind, gusts, precipitation, visibility, temperature, pressure, and K-index geomagnetic activity. The app compares those conditions with your selected drone profile so the result reflects the aircraft you actually fly.

SMARTER DECISION ENGINE

The new assessment system uses more drone parameters, including aircraft class, wind limits, payload capability, weight, flight type, and specialization. Guidance is more practical across compact consumer drones, professional platforms, enterprise aircraft, and agricultural drones.

HOURLY AND 9-DAY PLANNING

The redesigned Hourly view helps you scan upcoming conditions, find safer windows, and understand the main risk at each hour. The 9-Day Forecast gives a longer planning view with drone-aware safety context, daily risk signals, and detailed assessment sheets.

WEATHER DETAILS PILOTS NEED

• Wind speed, gusts, direction, and wind by altitude
• Rain risk and precipitation amount
• Visibility for visual flight operations
• K-index monitoring for GPS and compass reliability
• Temperature, pressure, humidity, and key forecast trends
• Custom locations and unit preferences

NFZ MAPS AND NOTAMS

Premium tools include no-fly zone maps, airport restriction context, and official FAA NOTAM data to help you review nearby airspace before you fly.

APPLE WATCH SUPPORT

Check flight status, key metrics, synced location data, and watch face complications directly from Apple Watch.

SMART DAILY BRIEFINGS

Optional notifications can provide forecast-based daily flight briefings using your selected location, drone profile, and the current decision engine result.

PRIVATE BY DESIGN

Weather4Fly does not require an account. Your drone, units, language, and preferences stay on your device. Location is used to retrieve local weather and support flight planning. The first 8 hours of weather forecasts and analysis data are completely free. Other features require a Premium subscription. Whether you fly for photography, mapping, inspection, agriculture, or recreation, Weather4Fly helps you understand the weather before takeoff and make a safer flight decision.
