METAR (Meteorological Aerodrome Report) is the standard format for reporting current weather conditions at airports worldwide. Issued every 30–60 minutes, it includes wind direction and speed, visibility, sky condition and cloud heights, temperature, dewpoint, and altimeter setting. Special METARs (SPECI) are issued when conditions change significantly.
TAF (Terminal Aerodrome Forecast) provides a weather forecast for the area within 5 nautical miles of an airport, valid for 24–30 hours. Issued every 6 hours by national weather services, TAFs use FM (from), TEMPO (temporary), BECMG (becoming), and PROB (probability) groups to describe changing conditions.
