Travellers spending the current holiday weekend in Los Cabos’ sun-drenched corridors will need to make significant adjustments to their beach itineraries. Municipal Civil Protection authorities have officially issued a critical ocean alert in response to a powerful maritime event known as a “mar de fondo” (deep-ocean swell). This phenomenon is currently causing hazardous conditions along the western coastline of the Baja California Peninsula, the Gulf of California, and the Pacific Ocean.
This safety advisory was issued on Saturday, March 14th, and is expected to remain in effect until Monday, March 16th. Before packing beach bags and heading to sandy shores, it is critical to understand the nature of this alert and the specific restrictions imposed on local beaches. A mar de fondo is not a localised storm; instead, meteorologists describe it as a massive system of deep-ocean energy. This system pushes heavy swells towards the coast, creating highly volatile hydrodynamic environments.
The Mechanics of the Swell
On the Pacific coast, wave heights ranging from 1.8 to 2.4 metres (approximately 6 to 8 feet) are currently being recorded. These towering waves are accompanied by wind gusts that have been measured at speeds up to 36 km/h. However, it is emphasized by safety experts that the primary threat is not merely the visible height of the crashing surf.
The true danger is found in the massive, invisible rip currents that are generated beneath the surface by these deep-water swells. These currents possess enough power to drag even the most proficient, Olympic-level swimmers away from the shore in a matter of seconds. Due to this severe risk of drowning, red flags have been raised by ZOFEMAT (the Federal Maritime Terrestrial Zone authority) lifeguards across the vast majority of popular tourist destinations in both Cabo San Lucas and San José del Cabo.
Restricted Zones: Red Flag Designations
When a red flag is displayed, it indicates that the water is highly dangerous and entry into the ocean is strongly discouraged. The following beaches in Cabo San Lucas are currently affected by these restrictive measures:
- All Riu Properties (including Riu Palace, Riu Santa Fe, and Riu Baja California)
- Villa del Palmar, Villa del Arco, and Villa La Estancia
- Las Viudas (The Widows)
- Santa María
- El Chileno
- El Tule
- Las Ollas, Curva del Soldado, and Migriño
Similarly, several prominent locations in San José del Cabo have been placed under lockdown to ensure public safety:

Safe Havens: Where the Yellow Flag Flies
Although major coves and expansive stretches of the coastline have been closed to swimmers, the entirety of the shoreline is not considered off-limits. Extreme caution is still mandated, but several geographically protected areas are currently flying a yellow flag. This designation signifies that the water remains open for limited use, though visitors are advised to stay close to the shore and remain vigilant of sudden changes in water behaviour.
The following Yellow Flag locations have been identified as accessible:
- El Corsario (Empacadora)
- The marina-facing side of Breathless
- Hacienda
- Pueblo Bonito Rose
- Cascadas de Baja
- La Ribera and Surgidero (located in the Northern Zone)
Official Directives and Safety Protocols
Lifeguards and Civil Protection personnel enforce these red flags to prevent catastrophic incidents. All visitors are expected to follow all posted signage. It is also recommended that crashing shorebreaks be avoided altogether. Travellers are encouraged to use the heated infinity pools provided by their respective resorts until the ocean energy is expected to settle, which is currently scheduled for Tuesday.
According to the Mexican government’s Civil Protection guidelines, a mar de fondo can cause a sudden rise in sea levels that extends further up the beach than typical waves. As a result, even those walking along the shoreline are advised to keep a safe distance from the water’s edge to avoid being swept away by sudden surges.
