If you are currently looking out at the Pacific Ocean from your resort balcony in Los Cabos, you will notice a stark, undeniable warning flying in the wind: black flags.
As Category 5 Hurricane Polo churns aggressively off the coast of the Baja peninsula, local authorities are taking zero chances with public safety. Due to a massive increase in violent wave action, strong wind gusts, and rapidly deteriorating maritime conditions, all beaches across Los Cabos have been officially closed to the public. The ports of Cabo San Lucas and San José del Cabo have also been completely shut down to all maritime navigation.
If you are vacationing on the peninsula this weekend, your itinerary needs an immediate adjustment. Here is exactly what is happening on the ground and why military personnel are currently patrolling the coastline.

The Black Flag Mandate and Active Evictions
A black flag on a Mexican beach does not just mean swimming is prohibited; it means the beach itself is entirely closed, and walking near the waterline is strictly forbidden.
Because tourists frequently underestimate the sheer power of Pacific swells during a tropical cyclone, municipal authorities have deployed a massive, coordinated security operation to enforce the closures. Francisco Cota Márquez, the director of Civil Protection and Risk Management for Los Cabos, confirmed that specialized brigades are actively sweeping the most popular tourist zones.
This is not a polite suggestion. Because individuals were found ignoring the initial warnings, the local government has called in federal backup. Elements of Public Security, the Mexican Navy (Semar), and the National Guard are now actively patrolling the sand. During the initial sweeps across Médano Beach, Costa Azul, and Acapulquito, military and civil protection personnel had to physically remove approximately 15 people who refused to vacate the high-risk zones.

Why the Sand is So Dangerous Right Now
A Category 5 hurricane does not need to make direct landfall to cause life-threatening conditions on the coast.
Hurricane Polo is pushing massive, long-period swells directly into the Baja shoreline. The ocean is currently experiencing aggressive, unpredictable surges that can easily drag a grown adult into the undertow in seconds. The sheer volume of water is already overwhelming local infrastructure.

According to on-the-ground reports, the beach access points and adjacent parking areas at Ocho Cascadas and Costa Azul have been completely flooded by surging seawater.
The impacts are extending beyond the water. The dangerous wind gusts and surging tides have forced popular beachfront restaurants along El Médano to completely shut down operations, evacuate their staff, and secure their facilities until the storm passes.

How to Navigate the Weekend
If you are checked into a beachfront resort, you must exercise extreme caution and strictly follow the directives of both local authorities and your hotel security staff.
- Do Not Approach the Ocean: Do not walk down to the waterline to take photos or record videos of the crashing waves. Rogue waves can surge dozens of feet past the normal high-tide line without warning.
- Respect the Perimeters: If your resort has roped off beach access or posted guards near the sand, do not attempt to bypass them.
- Utilize Resort Amenities: This is exactly why luxury resorts in Cabo build massive, temperature-controlled infinity pools. Move your afternoon plans inward, grab a seat at a sheltered lobby bar, and stay entirely off the sand.
Civil Protection will continue to monitor the trajectory of Hurricane Polo around the clock. The black flags will remain flying, and the military patrols will stay active, until the ocean completely settles and authorities officially declare the beaches safe for recreational use.
