Terminal Aerodrome Forecast

What is terminal aerodrome forecast?

A Terminal Aerodrome Forecast (TAF) is a weather prediction covering the area within a 5 statute mile radius around an airport. Each TAF is valid for a 24-hour period and is updated four times daily. Think of it as the "airport-specific forecast"—where a METAR tells you the weather right now, a TAF tells you what to expect.

Also known as: TAF, terminal aerodrome forecast
