A METAR (Meteorological Aerodrome Report) is a standardized weather observation report issued by airports, typically every 30 minutes. It includes wind direction and speed, visibility, cloud cover, temperature, dew point, and altimeter setting — all the data a pilot needs to assess conditions for landing or takeoff.

A TAF (Terminal Aerodrome Forecast) is an aviation weather forecast covering a 24-30 hour period for a specific airport. It uses the same format as METAR but describes expected future conditions, including wind, visibility, and precipitation changes over time.

What is an ICAO airport code?

An ICAO code is a four-letter identifier assigned to airports worldwide. Examples: EGLL (London Heathrow), KJFK (New York JFK), KLAX (Los Angeles), EDDF (Frankfurt), YSSY (Sydney). ICAO codes are used in aviation weather reports, NOTAMs, and flight plans.

A METAR is a standardized weather observation issued by airports every 30 minutes, containing wind, visibility, clouds, temperature, dew point, and altimeter setting — everything a pilot needs to assess approach and landing conditions.

METAR is an observation of current conditions. TAF (Terminal Aerodrome Forecast) is a 24-30 hour forecast using the same format. Both use ICAO codes and the same unit conventions.
