METAR Decoder

Type an airport code to pull its live report, or paste any raw METAR, and read it back in plain English. The decoder pulls out the station, observation time and age, wind, visibility, sky and ceiling, temperature and dewpoint, and altimeter — then badges the conditions with the standard VFR, MVFR, IFR, or LIFR flight category so you know at a glance whether it's a day to fly.

Flight category follows the FAA ceiling and visibility thresholds and always takes the more restrictive of the two. For training and situational awareness — always brief official weather sources before flight.

Plain English

  • Wind 250° at 12 kt, gusting 18
  • Visibility 10 SM
  • Sky clear
  • Temp 18°C / Dew 12°C
  • Altimeter 30.12 inHg

For training and situational awareness — always brief official weather sources before flight. Meter-based visibility (e.g. 0800) and other non-US groups aren't decoded.
