Canary Islands Phone Warning: New Emergency Alert System to Protect Tourists from ‘Silent’ Dangers

Published on December 18, 2025

For millions of British sun-seekers, the Canary Islands represent the ultimate escape. Whether it’s the dramatic cliffs of Los Gigantes in Tenerife or the golden dunes of Maspalomas in Gran Canaria, these islands offer a rugged beauty that is hard to match. However, that very beauty can turn deadly in an instant. Following a string of tragic accidents, local authorities are now pushing for a major technological upgrade to keep holidaymakers safe: a direct-to-phone emergency warning system.

A Winter of Tragedy

The call for enhanced safety measures comes on the heels of a devastating period for the archipelago. In the last two months alone, seven people have lost their lives to the treacherous Atlantic swells surrounding Tenerife.

Most recently, a somber cloud was cast over the popular Los Gigantes coast when four tourists were swept away at a natural ocean pool. Despite swimming bans and visible warnings, the power of the waves proved insurmountable. These incidents have highlighted a critical gap in communication: how do you warn someone who isn’t watching the local news or following Spanish authorities on social media?

The Solution: ES-Alert for Tourists

Enter CIT Sur (The Centre for Tourism and Initiatives of South Tenerife). This influential tourism body is officially requesting that the regional government expand the use of the ES-Alert system.

Currently, ES-Alert is reserved for “Level 1” catastrophes—think volcanic eruptions (like the 2021 La Palma event) or widespread wildfires. CIT Sur wants to bring this technology down to “Level 3,” allowing it to be used for more frequent but equally dangerous “silent” threats like:

• Abnormal Wave Activity: Warning swimmers before they enter natural pools.
• Adverse Weather: Alerting hikers to flash floods or extreme winds in the highlands.
• High-Temperature Alerts: Preventing heatstroke during intense Saharan dust events (Calima).

How It Works: No App Required

One of the most significant advantages of the ES-Alert system is its accessibility. Unlike traditional travel apps that require a download and an active data plan, ES-Alert uses cell broadcast technology.

If you are within a specific geographical area—for example, near a dangerous hiking trail in Teide National Park—your 4G or 5G phone will emit a loud, distinct alarm and display a text message. Crucially for Brits, these messages can be broadcast in multiple languages, ensuring that the warning is understood instantly, regardless of your nationality.

The “Digital Bubble” Problem

David Pérez, Vice President of CIT Sur, pointed out a modern dilemma facing tourism safety. “Social media algorithms and the digital environment do not lead tourists to our local news outlets,” he explained.

When you’re on holiday, your feed is likely filled with restaurant recommendations and sunset photos, not local weather warnings. By sending an alert directly to a visitor’s handset, authorities can pierce through that “digital bubble” and provide real-time, life-saving information exactly when it is needed.

Personal Responsibility vs. Government Intervention

While the proposed system is a massive step forward, authorities are quick to remind travelers that technology is not a substitute for common sense. The tragedy at Los Gigantes occurred in an area where warnings were already in place.

The goal of the ES-Alert expansion is to provide an extra layer of protection—a final, undeniable “ping” on your phone that says, “The path ahead is closed” or “The sea is too dangerous today.” It is about making sure that every tourist has the information they need to make a safe decision, even if they’ve missed the physical signs or the local radio broadcast.

Looking Ahead: A Safer Archipelago

As the Canary Islands continue to see record-breaking tourist numbers, the pressure to modernize safety protocols is mounting. With the proposal now heading to the General Directorate of Security and Emergencies, holidaymakers could see these alerts active as early as the 2026 season.

For the regular visitor to Tenerife, Lanzarote, or Fuerteventura, this change should be seen as a welcome companion. It’s a small interruption that could mean the difference between a memorable holiday and a tragic headline.
