About this decoder
It understands the common groups of ICAO and US METARs: wind, visibility, runway visual range, weather, cloud, temperature, pressure, wind shear and trends. National remarks after RMK are shown but not decoded. TAFs are not supported; see how to read a TAF. The flight category uses the FAA/NWS thresholds described in this guide; it is a summary, not legal weather minima. Want the real thing? Open a live report and paste it here.
