AeroWindy is a free real-time aviation weather map for US pilots. It displays live METAR wind data, radar overlays, and AI-detected hazards including wind shear corridors, IFR conditions, structural icing risks, and turbulence across the continental United States — all updated every 5 minutes.

How is AeroWindy different from other aviation weather apps?

AeroWindy combines live METAR data with Google Gemini AI to automatically detect patterns pilots care about — wind shear corridors, IFR clusters, icing zones, and fog risks — and synthesizes them into plain-English pilot briefings. Unlike basic weather apps, AeroWindy runs multiple AI agents (WindAgent, HazardAgent, TrendAgent, BriefingAgent) continuously in the background so you get proactive hazard alerts, not just raw data.

How often is the aviation weather data updated?

Weather data including METARs, winds aloft, and PIREPs are refreshed every 5 minutes from the FAA Aviation Weather Center API. The AI agent analysis runs automatically after each data refresh cycle.

What AI features does AeroWindy use?

AeroWindy uses Google Gemini AI to power four autonomous agents: WindAgent (detects wind shear corridors and mountain wave), HazardAgent (identifies IFR clusters, icing zones, and fog risk), TrendAgent (monitors rapid weather changes between data cycles), and BriefingAgent (synthesizes all findings into a plain-English pilot situation briefing). There is also an interactive Pilot Copilot chatbot you can ask specific questions about current conditions.

Is AeroWindy free to use?

Yes, AeroWindy is completely free and requires no account, login, or credit card. All features including AI hazard intelligence, TAF forecasts, NOTAM decoding, and the Pilot Copilot chatbot are available at no cost.

What airports does AeroWindy cover?

AeroWindy covers all METAR-reporting airports across the continental United States, including major international airports (like KLAX, KJFK, KORD), regional airports, and general aviation fields. You can search by ICAO code or airport name to jump directly to any airport.

How does AeroWindy detect wind shear?

The WindAgent automatically analyzes adjacent METAR stations and flags wind shear corridors where wind speed differences exceed 15 knots or directional shifts exceed 45 degrees between nearby airports. These corridors are highlighted on the map as hazard zones with severity ratings.

Does AeroWindy have a crosswind calculator?

Yes. AeroWindy includes a built-in crosswind calculator. When you select any airport, it automatically shows the crosswind and headwind component for each runway based on the current METAR wind direction and speed. It also recommends the best runway to use given current wind conditions.

What is a TAF and how does AeroWindy display it?

A Terminal Aerodrome Forecast (TAF) is an official 24-30 hour weather forecast issued for specific airports by the National Weather Service. AeroWindy displays TAFs as a visual 24-hour timeline showing wind direction, speed, visibility, ceiling, and weather conditions for each forecast period — with plain-English summaries so you don't have to decode raw TAF codes yourself.

What are NOTAMs and how does AeroWindy decode them?

NOTAMs (Notice to Air Missions) are official notices about changes to airport facilities, airspace restrictions, and hazards that pilots must review before flight. AeroWindy fetches active NOTAMs for any searched airport and uses AI to provide plain-English summaries of each notice, removing the need to manually decode cryptic NOTAM shorthand.

How does AeroWindy identify IFR conditions?

The HazardAgent scans all METAR stations in the current map view and flags airports reporting ceiling below 1,000 feet or visibility below 3 miles (IFR minimums). Clusters of nearby IFR airports are highlighted as IFR zones on the map, making it easy to spot large-scale instrument conditions affecting a region.

Can AeroWindy show structural icing risk?

Yes. AeroWindy's HazardAgent identifies airports reporting conditions favorable for structural icing — temperatures between -20°C and 0°C combined with visible moisture (OVC/BKN ceilings or precipitation). These icing risk zones are displayed on the map with severity indicators and appear in the AI pilot briefing.

Does AeroWindy show winds aloft data?

Yes. AeroWindy displays winds aloft at 6 altitude levels: Ground, 3,000 ft, 6,000 ft, 9,000 ft, 12,000 ft, and 18,000 ft. You can switch between altitude layers using the control panel, and wind barbs update to show direction and speed at your selected altitude across the entire US map.
