A scheduled test of Saudi Arabia’s emergency warning systems will take place on Monday, October 20, 2025, involving fixed sirens and mobile phone alerts. The test will be conducted across specific governorates in Riyadh, Tabuk, and Makkah regions as part of a broader initiative to verify the readiness of national alert infrastructure and raise public preparedness.

Regions and areas included in the test

The General Directorate of Civil Defense confirmed that the siren test will be carried out in the following locations:

  • Riyadh Region:
  • Tabuk Region:
    • All governorates within the region
  • Makkah Region:

These areas have been selected to participate in the fixed siren component of the test. The sirens will activate at 1:15 p.m., sounding the designated emergency tones.

Schedule and alert sequence

The test will follow a precise timeline involving both mobile alerts and sirens:

  • 1:00 p.m. – Warning messages will be sent to mobile phones using a new behavioral tone.
  • 1:10 p.m. – A national alert tone will be broadcast as a second layer of testing.
  • 1:15 p.m. – Fixed sirens will sound in the designated areas across Riyadh, Tabuk, and Makkah.

This sequence is designed to test the layered response mechanisms and verify the synchronization between mobile alerts and physical siren systems.

Purpose and technical scope of the test

The upcoming drill has two primary objectives:

  • Assess System Readiness:
    The test will examine the operational efficiency of the fixed sirens and the broader National Early Warning Platform, which utilizes cellular broadcast technology to send alerts to mobile devices.
  • Boost Public Awareness and Preparedness:
    By simulating emergency scenarios, authorities aim to ensure that residents are familiar with alert tones, can distinguish between types of warnings, and understand how to respond in case of actual emergencies.

Notably, the exercise will extend beyond the siren zones. The mobile-based early warning platform will send test messages nationwide via cellular broadcasting, accompanied by distinct audio alerts to ensure they are easily recognized.

Wider implications and public cooperation

While the fixed sirens will be limited to selected governorates, the simultaneous test of the mobile alert system will reach all regions of the Kingdom. This dual-layer strategy allows civil defense authorities to:

  • Evaluate system performance under real-time, nationwide conditions
  • Identify potential gaps or failures in signal coverage
  • Fine-tune alert behavior tones for clarity and urgency

The Civil Defense urges the public to treat the alerts as part of a routine preparedness exercise and not to panic when sirens or warning messages are heard or received.
