When is ATIS recorded?

The recorded Automatic Terminal Information Service (ATIS) is typically updated once per hour following the issuance of a new METAR report. This schedule allows for any important changes in weather conditions or operational information to be communicated to pilots in a timely manner. By syncing updates with METAR publications, ATIS ensures that the information provided is as current and relevant as possible, enabling pilots to make informed decisions upon arrival at an airport.

Updating ATIS every 30 minutes or every 15 minutes would result in unnecessary repetition, and doing so every minute during operation would create an impractical information overload that could confuse instead of assist pilots. The hourly update schedule strikes a balance between providing timely information while not overwhelming users with constant changes.
