How this service works
Gets live weather observations for JFK airport.
Output
Returns an array of recent METAR observations for the specified airport including time, temperature, dewpoint, wind speed/direction, visibility, pressure (inHg), cloud layers with altitude, flight rules (VFR/IFR/MVFR), relative humidity, raw METAR string, and human-friendly wind and cloud descriptions. Paginated with a next cursor link.
Example use cases
Example prompt
“What are the current weather conditions at JFK airport — give me the temperature in Fahrenheit, wind speed and direction, visibility, cloud layers, and flight rules?”
Technical details
Endpoint
GEThttps://stable-travel-git-migrate-stabletravel-router-140-merit-systems.vercel.app/api/flightaware/airports/KJFK/weather/observationsWhen to prefer
Use this endpoint when you need structured, parsed METAR weather data for a specific airport including flight rules classification, cloud layers, wind, and visibility — especially when you need both human-friendly summaries and raw METAR strings for aviation planning or pre-flight checks.
Side effects
- Invalid or unknown ICAO airport code returns an error
- Airport has no recent METAR data available
- Payment not provided or insufficient USDC balance returns 402
- Rate limiting or service unavailability returns 5xx
- Invalid temperature_units enum value returns validation error
