Nationwide Warning Day: Sirens will sound on September 11th – be ready!

On Thursday, September 11, 2025, all citizens in Germany will face an important test: the fifth nationwide warning day will take place. On this occasion, all districts and municipalities, including Cologne, are called upon to test various warning systems. The alarm is initiated at 11 a.m. with a characteristic rising and falling howling sound lasting one minute. The aim of this test alarm is not only to check the technical warning equipment, but also to raise public awareness of the issue of security and crisis prevention.

As the Augsburger Allgemeine reported, the results of the exercises will be recorded in an online survey. This survey will start in time for Warning Day and will remain open until September 18, 2025. The Federal Office for Civil Protection and Disaster Assistance (BBK) hopes that the feedback will provide valuable information on how to improve the warning systems.

Warning day: A test for all communities

Why is it so important that all communities participate? The warning day serves as a stress test for the warning infrastructure in Germany. As well as ka-news As explained, the warning is sent via various channels: radio, television, internet, social media, loudspeaker trucks, digital city information boards and of course sirens. This variety of warning devices is intended to ensure that the population is as well informed as possible.

At 11:45 a.m. a nationwide all-clear will be announced across all channels, with the exception of Cell Broadcast. This technology allows alerts to be sent directly to all smartphones that are turned on, even if they are in silent mode. This means that the warning systems reach millions of people in Germany.

Importance of citizen participation

BBK President Ralph Tiesler emphasized the importance of citizen participation. “It is important that people know how to be alerted in an emergency,” he said. This is also why feedback on the use of warning channels is so crucial. Only through active feedback can the systems be continuously improved and adapted to the needs of citizens.

However, in many municipalities, such as Stuttgart, no sirens will be heard as the corresponding systems are still being planned. This shows that there are regional differences in the operational readiness of the warning systems. In the Main-Tauber district, the sirens are not yet ready for use, apart from certain places that benefit from funding to improve their siren network.

While participation is voluntary for each community, the BBK encourages citizens to learn about the alert methods available. Information about this is available at www.warning-der-bevoelkerung.de and www.bbk.bund.de/bundesweit-warntag.

The nationwide warning day is not just a technical exercise, but also offers an opportunity for the population to address the issues of safety and personal precaution. Get involved and find out about the warning systems in your community!
