At The Cabo Sun, we love seeing everyone enjoying Los Cabos’ stunning beaches — but we also know that the ocean here demands respect.
This weekend was a prime example of why the beach flag system is so important, after nearly 100 beachgoers were escorted off the sand for trying to swim during dangerous conditions caused by Tropical Storm Ivo.

What Happened?
As Tropical Storm Ivo drifted away from the Baja California Sur coastline, it left behind more than just cloudy skies. Swells remained powerful, waves were unpredictable, and lifeguards had posted warning flags along several popular beaches in Cabo San Lucas and San José del Cabo.
Despite these warnings, authorities reported that almost a hundred people tried to swim or surf anyway. The joint operation — involving ZOFEMAT, the Navy, Public Safety, and Civil Protection — quickly stepped in to clear the beaches and keep everyone safe.
Francisco Cota Márquez, Director of Civil Protection, stressed that the ports may have reopened, but that didn’t mean it was safe for small boats or swimmers. In fact, San José del Cabo saw rainfall totals of up to 30 millimeters, and forecasters warned that precipitation could rise to nearly double that before conditions fully improved.

Why the Flag System Matters in Cabo
If you’ve spent time at the beaches here, you’ve probably noticed colored flags flying near the lifeguard stands or beach entrances. These aren’t just decorative — they’re a universal safety system that helps visitors know when it’s safe to swim:
- Green flag: Calm conditions, swimming allowed.
- Yellow flag: Caution — moderate waves or currents.
- Red flag: High risk — swimming strongly discouraged.
- Black flag: Extreme danger — water is off-limits.
When the black flag is up, the sea is closed for a reason. Strong rip currents, heavy surf, and storm-driven waves can easily overpower even experienced swimmers.

Why Tourists Are Tempted To Ignore It
We get it — you’ve booked your dream Cabo vacation, packed your swimsuit, and the idea of skipping beach time feels unthinkable. But storm conditions can be deceptive. Even if the sun is peeking through and the water looks calmer, dangerous undercurrents may still be lurking.
One traveler we spoke to compared it to “swimming in a washing machine — you don’t realize how strong the pull is until you’re in it.” That’s exactly why the safety teams act fast to keep people out.
Staying Safe While Still Having Fun
Bad weather doesn’t mean your Cabo beach day is ruined — it just means you may need to shift gears. Here are some great alternatives when the flags are red or black:
- Explore Cabo’s Marina — grab a coffee, people-watch, and shop for souvenirs.
- Take a food tour — local tacos, fresh ceviche, and Baja-style seafood are a must.
- Book a spa day — many resorts offer day passes even if you’re not staying there.
- Visit San José del Cabo’s Art Walk (seasonal) or browse the galleries year-round.
By taking the flag system seriously, you’re not only protecting yourself but also helping lifeguards and rescue teams focus on genuine emergencies rather than preventable situations.

The Bottom Line
Los Cabos’ beaches are one of the biggest draws for travelers, but they’re also part of a living, changing environment. Tropical storms like Ivo may come and go quickly, but the ocean’s after-effects — like high surf and rip currents — can linger for days.
As we at The Cabo Sun always say: the flags don’t ruin your beach day, they protect your future beach days. If you see red or black, swap your swim for a shoreline stroll, snap some incredible storm-surf photos from a safe distance, and save your swimming for when the green flag waves again.
It’s a small step that could make a big difference — and keep your Cabo memories sunny for all the right reasons.
