Cabo Issues Winter Health Advisory As Temperatures Drop: What Tourists Need To Know

Share The Article

If you’re packing for Los Cabos right now, you’re probably thinking swimsuits, sandals, and maybe a light cover-up for dinner. But this week, local authorities added something a little less “vacay aesthetic” to the list: a winter health advisory.

We at The Cabo Sun have been tracking how winter in Los Cabos is shaping up for 2025 and what that means for travelers, from airport lines to beach safety. This latest advisory is aimed mainly at locals, but it absolutely applies to visitors too — especially families, older travelers, and anyone with underlying health issues.

Here’s what you actually need to know (and do) so a little cool breeze doesn’t derail your Cabo getaway.

So, How Cold Does Los Cabos Actually Get?

Let’s be clear: this is not “blizzard in Chicago” weather. Daytime highs in Los Cabos in winter still hover around the upper 70s to low 80s°F (about 25–27°C), with plenty of sunshine. The difference is in the mornings and evenings, when temps can drop into the upper 50s–low 60s°F (around 12–16°C).

That might sound mild on paper, but factor in wind, humidity, and the fact that most people are dressed for the beach, and it can feel surprisingly chilly — especially if you’re out on a boat, doing a sunrise tour, or heading into the mountains. In the Sierra de la Laguna, for example, cold fronts have even brought frost to plants on past winter mornings.

If you’re visiting Cabo in December and wondering what to pack, we’ve already broken down typical temps, crowds, and what that means for your suitcase in our month-by-month guide to December trips.

What The New Winter Health Advisory Says

According to the Municipal Health Institute, the advisory comes after a noticeable drop in temperatures across the Los Cabos municipality. Health officials are asking residents to reinforce self-care, with a special focus on:

• Children under 5
• Older adults
• Pregnant women
• Anyone with chronic or degenerative conditions (like heart or respiratory disease, diabetes, etc.)

The director of the Institute, Juan Carlos Costich Pérez, highlighted a few simple steps:

• Dress in warm layers when temps drop
• Cover your nose and mouth in cold, windy conditions
• Wear a face mask if you have respiratory symptoms
• Stay hydrated and consider boosting vitamin C
• Avoid self-medicating and see a doctor if you feel unwell

Even though the announcement is aimed at locals, those same tips are exactly what winter travelers should be doing, too.

Simple Things Tourists Can Do To Stay Healthy

Here’s how to translate that advisory into real-world Cabo vacation moves:

• Pack a real layer, not just a cute wrap. A light hoodie, cardigan, or packable jacket will make early-morning excursions, rooftop dinners, and sunset cruises way more comfortable. Our rundown of why winter in Los Cabos is one of Mexico’s ultimate escapes for 2025 also explains why those cooler evenings are actually a perk for sightseeing and dining.
• Don’t ignore a cough or sore throat. Travel + dry airplane air + cooler evenings can make respiratory bugs circulate more easily. If you start to feel off, take it easy instead of powering through.
• Hydrate like it’s still summer. Even when it feels cooler, the sun is strong and the air is dry. Dehydration makes you more vulnerable to illness.
• If you’re high-risk, be extra prepared. Bring any regular medications, a basic thermometer, and a simple “just in case” travel health kit approved by your doctor before you fly.

Local authorities are also rolling out a wider set of measures to keep tourists safe this winter, from dengue-prevention campaigns to extra inspections and awareness efforts, so this health advisory fits into a bigger safety picture for the season.

What If You Start Feeling Sick On Vacation?

Good news: if you’re staying at a resort in Los Cabos, you’re not on your own. Most properties work with on-call doctors and have a clear protocol if a guest starts feeling unwell. Your first call should be the front desk — from there, staff can coordinate a visit from a doctor or arrange transport to reputable private hospitals like BlueNet or H+ if needed.

We’ve laid out the whole process in detail in our guide to what happens if you get sick at a Los Cabos resort, including why travel medical insurance is a smart idea for winter trips.

If you’re staying in an Airbnb or condo, you’ll still find plenty of pharmacies and clinics in Cabo San Lucas and San José del Cabo. Staff at most hotels or property management companies can point you toward trusted options.

Extra Tips For Winter Travel In Los Cabos

A few more easy ways to stay safe and comfortable while you’re here this season:

• Watch the beach flags. Cooler air doesn’t always mean calmer seas. Rip currents can still be strong, and winter swells can be sneaky. Our Los Cabos beach flag guide explains exactly what every color means and why you should never go in just because the waves “look fine.”
• Check the broader safety picture. If you’re a planner, you might also want to look at the current U.S. State Department travel advisory for Los Cabos this winter to understand how official guidance lines up with what we’re seeing on the ground.
• Plan around cool mornings. Book your boat tours, pool days, and beach time for late morning or afternoon, and save early mornings or evenings for strolls around the marina or San José del Cabo’s Art District.

Bottom line: this winter health advisory is not a reason to cancel your trip. It’s simply a reminder that Los Cabos in winter isn’t 24/7 blazing heat — and that a couple of smarter packing choices and a bit of common sense will go a long way.

Layer up, keep an eye on how you’re feeling, and you’ll still get all the sunshine, whale watching, and epic tacos that make winter in Cabo such a sweet spot for travelers.
