Civil defence siren test on 11 September

A Bavaria-wide siren test will be held on 11 September 2025 at 11:00. The purpose of this siren test is to check that the civil defence siren system is working properly and to make the population aware of the meaning of the different siren signals.

The signal you will be hearing during this siren test is the one used to alert the general public to a public announcement. It consists of a siren wail that rises and falls over a sixty-second period. Its purpose is to warn of a serious threat to public safety and prompt people to switch on their radio sets to listen for announcements. You do not have to take any action when you hear the siren. This siren alert tomorrow is only a test.

Please note: For some people (possibly older people, refugees from war zones or children), loud warning signals can trigger fear or even distressing memories. We recommend that you prepare those around you who may be affected for the situation and, if possible, do not leave them alone during the alarm.
