Weather Apps for UK Drone Pilots: What to Use

Why Weather Apps Matter for Drone Pilots

Weather is the single most common reason drone flights are postponed or cancelled. Unlike manned aircraft pilots who have access to formal meteorological briefings (METARs, TAFs), drone operators typically rely on consumer weather services for their planning. Using the right combination of apps can significantly improve your decision-making about when and where to fly.

No weather app can tell you whether it is appropriate to fly in specific conditions — that remains the pilot's responsibility. What apps can do is provide data that informs your assessment.

General Forecast Apps

Met Office Weather

The Met Office is the UK's national weather service. Its app and website provide:

• Hourly forecasts for specific locations, including temperature, precipitation probability, wind speed, and wind direction
• Weather warnings (yellow, amber, red) that may affect flight operations
• Detailed 5-day forecasts and longer-range outlooks
• UK-specific data that can be more accurate for local conditions than global weather services

The Met Office data is sourced from the same numerical weather prediction models used by UK aviation meteorology, making it a reliable baseline for pre-flight planning.

BBC Weather

The BBC Weather app sources data from a combination of providers and offers a clean, accessible interface. It is useful for a quick overview but may lack the granularity of wind gust data that drone pilots need.

Wind-Specific Tools

Windy (Windy.com)

Windy is a visual weather platform that displays wind patterns as animated overlays on a map. For drone pilots, its strengths include:

• Animated wind flow visualisation — you can see wind patterns, convergence zones, and gusty areas at a glance
• Multiple data model comparison — you can switch between forecast models (ECMWF, GFS, ICON) to see where they agree or disagree
• Altitude layers — you can view wind conditions at different heights, which is relevant because wind at 100 m may differ significantly from ground level
• Cloud cover, rain, and temperature overlays
• A free tier that provides all the essential features for drone flight planning

Ventusky

Similar to Windy in concept, Ventusky provides animated weather maps with wind, rain, temperature, and cloud overlays. Some pilots prefer its interface for its clarity and colour scheme.

Drone-Focused Weather Apps

UAV Forecast

UAV Forecast is specifically designed for drone pilots and aggregates multiple data points relevant to flight planning:

• Go/no-go indicators based on wind, precipitation, visibility, and KP index (geomagnetic activity that can affect GPS)
• Satellite count and GPS accuracy predictions
• Nearby airspace and no-fly zone overlays
• Custom thresholds — you can set wind speed limits based on your specific drone's specifications

UAV Forecast is a useful starting point for flight planning, but it should not be your only source. Its data comes from third-party weather models and its no-fly zone database may not reflect the most current NOTAMs or temporary restrictions.

What to Check Before Every Flight

Regardless of which apps you use, a pre-flight weather check should cover:

• Wind speed and gusts — both at ground level and at your planned operating altitude
• Precipitation — current and forecast for the duration of your planned operation plus a margin for unexpected delays
• Visibility — fog, mist, haze, and low cloud can compromise VLOS
• Temperature — particularly relevant for battery performance below 5°C (see our Battery in Cold Weather guide)
• Sunset and sunrise times — ensure your operation fits within your planned lighting window
• Weather warnings — Met Office yellow, amber, or red warnings may indicate conditions unsuitable for any drone operation

Limitations of Weather Apps

All weather apps share certain limitations that drone pilots should understand:

• Forecasts are predictions, not measurements — actual conditions on site may differ from what any app shows, particularly for localised phenomena like thermals, sea breezes, and valley winds
• Spatial resolution — most forecast models operate on grid squares of 1 to 4 km. Conditions within that square may vary, especially in hilly or coastal terrain
• Update frequency — forecast data may be hours old by the time you check it. Always verify conditions on arrival at your flying site
• App data is advisory, not authoritative — no app output can substitute for the pilot's on-site assessment and judgement
