As you plan your getaway to our sun-kissed coastline, you may already be picturing your toes in the sand and an ice-cold drink in hand.
We at The Cabo Sun can’t blame you—Los Cabos’ postcard-perfect beaches are the stuff of vacation dreams. But before you grab your towel, here’s a critical heads-up on recent surf conditions and beach safety.
On July 11, 2025, the Zona Federal Marítimo Terrestre (ZOFEMAT) issued an alert that a mar de fondo swell could kick in around 11:00 a.m., prompting officials to raise red flags at every municipal beach. From that hour onward, water entry and all ocean-based activities are prohibited due to high waves, strong rip currents, and irregular breakers—hazards that even the most seasoned swimmers should respect.
What is mar de fondo?
Mar de fondo refers to distant ocean swells that travel across the Pacific before crashing unpredictably along our shores.
Unlike a typical surf break, these long-period swells can stir up the seafloor, creating sudden currents and wave peaks. We’ve seen stand-up paddle boarders and casual waders caught off guard when a rogue set crested.
If you’ve read our First-Timer’s Guide to Swimmable (and Unswimmable) Beaches, you know why respecting these natural rhythms is the difference between a flawless beach day and an emergency.
Official warnings and red flags
According to ZOFEMAT, the red flag signals a high-risk situation and the complete prohibition of water entry. Officials are asking all visitors to:
- Abstain from entering the water at any beach in Los Cabos.
- Follow lifeguard instructions immediately—they’re on duty to keep you safe.
- Keep a vigilant eye on children and teens, avoiding any distractions near the surf.
- Postpone shoreline activities until conditions improve.
If you’re staying at a beachfront resort, don’t be surprised when concierges remind you to check that red flag before heading out. It’s all part of Los Cabos’ enhanced safety measures, from clearer flag signage to lifeguards stationed at every shore.
Understanding the flag system
We’ve covered the four-flag warning system many times before here, but here’s a quick refresher:
- Green Flag: Calm waters—safe to swim.
- Yellow Flag: Moderate surf or currents—exercise caution.
- Red Flag: Dangerous conditions—swimming prohibited.
- Black Flag: Beach closed due to extreme hazards.
The key? Respect whatever color you see. Even a seemingly gentle swell can shift to dangerous in minutes.
Before you go: Smart packing tips
Packing light but smart sets the stage for a worry-free beach day.
Be sure to include reef-safe sunscreen, a wide-brimmed hat, UV-blocking sunglasses, and a reusable water bottle. Don’t forget a waterproof phone pouch and a small first-aid kit for minor scrapes.

Your Cabo Beach Confidence Checklist
Whether you’re chasing sunrise dips at Medano or planning a serene bodyboard session at Chileno, these tips will keep you secure:
- Scan the Shoreline. Look for flag posts before you lay down your towel. Red? Don’t risk getting in!
- Catch the Calm Windows. Early mornings (7–10 a.m.) and late afternoons typically bring gentler surf.
- Swim Under Watch. Stick to areas with active lifeguard towers—and know your exit points.
- Buddy System. Having a friend at your side is both safer and more fun.
- Ask at Check-In. Many hotels now provide quick beach safety briefings when you arrive.
Stay in the know
Beach conditions can change in the blink of an eye.
We at The Cabo Sun recommend checking flags and listening to alerts from local lifeguard stations.
Embrace the sun safely
Even with today’s red flags, Los Cabos remains one of the world’s preeminent beach destinations—once you know how to read the surf and heed the warnings, the golden sands and crystalline waters are all yours to explore.
No matter your beach vibe—adrenaline-fueled snorkeling at Santa María or barefoot strolls at Lover’s Beach—Cabo has a stretch of sand for every traveler, and now you’re set to enjoy it safely.
Here’s to safe adventures and unforgettable beach days!
