Airports: United States

The METAR and TAF decoder database holds 2,572 airports in United States. 1,760 of them have an IATA code and every one has an ICAO code, which in this country starts with BU, KA, KB, KC, KD, KE, KF, KG, KH, KI, KJ, KK, KL, KM, KN, KO, KP, KR, KS, KT, KU, KV, KW, KX, KY, KZ, PA, PF, PH, PO, PP and PT. For every airport on the list below the site shows the current METAR and the TAF forecast decoded into plain English, together with a map, runway data and a clock in the airport's local time.

Largest airports in United States

The most significant airports in the database for this country are Denver International Airport (KDEN/DEN), Harry Reid International Airport (Las Vegas) (KLAS/LAS), John F. Kennedy International Airport (New York) (KJFK/JFK), Albuquerque International Sunport (KABQ/ABQ) and City of Colorado Springs Municipal Airport (KCOS/COS).

Weather reports identify an airport by its four-letter ICAO code, not by the IATA code - which is why the METAR for KDEN is available even for airports with no ticketing code. The airports of United States are spread across 2,055 municipalities listed in the database.

Airports by classification

How the airports break down: small airports and airfields - 1,629; medium-sized airports - 813; large airports - 95; heliports - 20; seaplane bases - 15.

The classification comes from OurAirports and describes the size of the infrastructure, not passenger traffic. Regular METAR and TAF reports come mostly from the larger airports; small airfields often publish none at all - in that case the nearest reporting station is listed in the "nearby airports" section of the airport page.

Geographic span and time zones

The northernmost airport in the database is Wiley Post Will Rogers Memorial Airport (Utqiaġvik) (PABR/BRW) (71°17'N), the southernmost is Hilo International Airport (PHTO/ITO) (19°43'N). East to west the extremes are Eareckson Air Station (Shemya) (PASY/SYA) (174°07'E) and Adak Airport (PADK/ADK) (176°39'W).

The highest airport is Lake County Airport (Leadville) (KLXV/LXV) at 9,927 ft / 3,026 m above sea level, the lowest is Cliff Hatfield Memorial Airport (Calipatria) (KCLR/CLR) (-182 ft / -55 m). Elevation matters when reading a report: METAR cloud bases are given above aerodrome level, not above mean sea level.

The airports here sit in 29 time zones: America/Adak, America/Anchorage, America/Boise, America/Chicago, America/Denver, America/Detroit, America/Hermosillo, America/Indiana/Indianapolis, America/Indiana/Knox, America/Indiana/Marengo, America/Indiana/Vincennes, America/Juneau, America/Kentucky/Louisville, America/Kentucky/Monticello, America/Los_Angeles, America/Menominee, America/Moncton, America/New_York, America/Nome, America/North_Dakota/Beulah, America/Phoenix, America/Regina, America/Sitka, America/Toronto, America/Vancouver, America/Winnipeg, America/Yakutat, Asia/Anadyr and Pacific/Honolulu. METAR and TAF are always issued in UTC (the "Z" suffix), which is why every airport page runs a clock in the airport's own local time next to the report.

METAR and TAF for airports in United States

Each airport page shows the raw METAR plus a full decode: flight category (VFR, MVFR, IFR, LIFR), wind direction and speed with gusts, visibility, weather phenomena, cloud layers with their bases, temperature, dew point and QNH pressure. The TAF forecast is split into its validity periods including the change groups (BECMG, TEMPO, PROB).

METAR is normally issued every 30 or 60 minutes and TAF four times a day, with extra amendments when conditions change. The data comes from the Aviation Weather Center (NOAA) and is fetched live on every visit.

How to read a METAR and TAF report?

METAR is a recurring (usually every 30-60 minutes) weather report issued by an airport: wind, visibility, weather phenomena, cloud cover, temperature, dew point and pressure. TAF is a forecast for the next 24-30 hours, split into change groups (FM, BECMG, TEMPO, PROB).

The flight category badge (VFR, MVFR, IFR, LIFR) is a quick summary of how demanding conditions are for landing - from good visibility (VFR) to very limited visibility and a low cloud base (LIFR).

Reports are given in UTC (universal time), not the airport's local time.
Wind direction is the direction it's blowing "from", in true/magnetic degrees, plus speed.
Visibility and cloud base determine the flight category (VFR/MVFR/IFR/LIFR).
MetarTaf Decoder translates every group of the report into a full sentence, without guessing abbreviations.
