METAR Lookup — What It Does

Look up any airport instantly
Type a 4-letter ICAO airport code (e.g. KSEA for Seattle, KORD for Chicago, KLAX for Los Angeles) and get live weather data in seconds

Current conditions (METAR)
See the latest official weather observation — temperature, dewpoint, winds, gusts, visibility, cloud layers, and altimeter setting, all decoded into plain readable values from the raw report

Flight category at a glance
Every lookup shows whether conditions are VFR, MVFR, IFR, or LIFR in a large color-coded banner — green, blue, red, or purple

Terminal forecast (TAF)
View the official weather forecast for the next 24–30 hours broken into time periods, each with its own predicted conditions and flight category

Interactive map
See the searched airport on a map alongside surrounding stations, each dot colored by current flight conditions. Click any nearby station to look it up. Includes a live radar overlay

Airport charts
Browse and view official FAA instrument approach plates, departure procedures, arrival routes, and airport diagrams without leaving the app

SIGMETs & AIRMETs
See all active weather advisories across the US — severe turbulence, icing, low IFR — with a red count badge on the tab when hazards are in effect

ATIS
Displays the latest arrival and departure information broadcasts for major airports
