Los Cabos Health Officials Urge Tourists To Not Enter The Water For 4 Days

Share The Article

We at The Cabo Sun want you to have the best—and safest—beach days in Los Cabos.

After Hurricane Lorena’s heavy rains sent arroyos rushing toward the coast, Baja California Sur’s Health Secretariat issued a simple, temporary request: avoid entering the ocean for the next 96 hours (four days) while water quality returns to safe levels.

The guidance is statewide and includes the beaches of Los Cabos.

Why the 4-day pause?

When seasonal storms hit, runoff carries mud and urban debris into near-shore waters. Health officials say that it can temporarily spike microorganisms that may lead to stomach illness, ear and eye infections, or skin irritation.

Waiting four days gives tides and waves enough time to disperse contaminants while authorities test the water and publish results. Sampling is handled by COEPRIS (the State Commission for Protection against Sanitary Risks) and analyzed by the state’s public health lab.

This recommendation came right after Lorena’s pass near the peninsula, which also brought strong surf and flooding across parts of BCS. If you’re tracking the broader storm picture, our recent coverage explains the conditions Lorena created along the coast and why officials moved quickly with beach safety steps.

What that means if you’re here now

• Don’t swim or wade for the recommended period. Check official updates before re-entering.
• Watch the beach flags. In addition to water-quality guidance, local lifeguards may raise red or black flags for surf hazards. Here’s our refresher on what each color means and how to interpret them on Cabo beaches.
  • See our quick flag guide and the Medano-focused update.
• Heed local closures. During peak impacts from Lorena, Los Cabos authorities raised black flags and temporarily closed some beach accesses; expect those to ease after clean-up and water-quality checks.

Can you still enjoy the beach?

Absolutely—just pivot from swimming to shoreline time for a couple days:

• Morning walks and sunset photo ops along the sand (stay back from shore break).
• Beachfront dining and marina people-watching while crews finish clean-up. If you’re wondering how the hospitality scene is bouncing back, our on-the-ground report breaks down what’s open and how fast services are returning. Read: Should I Cancel My Trip? On-The-Ground Report.
• Nightlife update: Many venues paused operations during the weather event and are in clean-up-and-reopen mode now, especially around the marina. Check the latest here: Cabo Bars & Restaurants Assess Storm Impact.

Food & health notes while runoff recedes

Alongside the beach guidance, health authorities temporarily suspended some street-food sales in specific areas affected by sewage runoff until conditions normalize. That’s a standard precaution after big rains and is being reviewed as sites are cleared.

When will it be OK to swim again?

The Health Secretariat’s 96-hour window is designed to cover the highest-risk period, after which officials will share testing results and adjustments. Expect staggered reopenings as beaches are inspected and flagged appropriately. We’re monitoring official channels and will update readers as soon as COEPRIS posts fresh water-quality data and the municipality confirms which access points are good to go.

Smart safety checklist (save this)

• Check today’s guidance from the Government of BCS or Health Secretariat before heading out.
• If you see black flags, the water is closed—no entering, period. Use the time to explore town or book a spa/museum day.
• Rinse off after beach walks and avoid tide pools for now; they can concentrate contaminants. (This is a common post-storm best practice.)
• If you experience GI upset, ear pain, or skin irritation after accidental exposure, seek care and mention recent storm runoff.

Los Cabos knows how to bounce back quickly, and the goal of this short pause is to keep your vacation healthy while nature and clean-up crews do their thing. We’ll continue tracking official notices and will keep our readers updated with practical, traveler-first guidance.
