How this service works
Get weather observations (METAR) for a specific airport
Output
Returns a structured weather observation object for the requested airport including: temperature, dewpoint, pressure (mbar and inHg), wind speed, wind direction, wind variability, visibility (miles), humidity percentage, cloud layers, human-readable cloud and wind descriptions, flight rules classification (VFR/IFR/MVFR/LIFR), density altitude, raw METAR string, and observation timestamp.
Example use cases
Pre-flight weather briefing check
“Pull the latest METAR for KORD — I need the current temperature in Celsius, wind speed and direction, visibility, and whether it's VFR or IFR before I file my flight plan.”
Departure airport wind check for pilots
“What's the wind doing at KSFO right now? I need speed, direction, and whether it's variable — and tell me the current cloud ceilings too.”
Real-time airport weather monitoring
“Give me the current pressure, humidity, and flight rules at KJFK right now in Fahrenheit — I want to know if conditions have improved since this morning.”
Technical details
Endpoint
GEThttps://stabletravel.dev/api/flightaware/airports/KDEN/weather/observations?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, parsed METAR weather data for a specific airport, especially for aviation decision-making such as flight rules assessment, wind analysis, and ceiling/visibility checks. Prefer this over generic weather APIs when you need aviation-specific outputs like flight rules classification, density altitude, raw METAR strings, or wind variability flags. Ideal for real-time pre-flight briefings and automated airport condition monitoring.
Side effects
- Invalid or unknown ICAO airport code returns an error or empty response
- Airport has no active weather station — may return null fields or nearby airport data if return_nearby_weather is true
- Stale or missing METAR data at unmanned airports
- Payment failure (x402 protocol) if insufficient USDC balance
- Timestamp query for non-existent historical observation returns empty result
