Los Cabos is officially gearing up for a massive winter high season. As freezing temperatures and snowstorms sweep across the United States and Canada, hundreds of thousands of travelers are flocking to the mega-resorts of the Baja California peninsula for a dose of guaranteed sunshine and poolside margaritas.
The good news is that Cabo remains a premier “security island.” The U.S. State Department maintains a standard Level 2 advisory for Baja California Sur (the exact same safety rating applied to destinations like France and the UK), meaning the region is incredibly safe for tourists.
However, maximizing your vacation and avoiding major headaches during the peak winter months requires some insider knowledge. From navigating airport gauntlets to understanding exactly how your all-inclusive resort operates during maximum capacity, here are the top eight things every traveler needs to watch out for this winter.

1. The Federal “Vape Ban” at Customs
Your luxury resort vacation can easily be derailed before you even step outside the airport. Following strict federal reforms, bringing any vaping device or e-liquid into Mexico is legally classified as an illegal importation.
SJD International Airport customs officials now utilize high-resolution X-ray scanners specifically calibrated to identify lithium batteries and vape cartridges in tourist luggage. This is a zero-tolerance policy. If you are caught, your devices will be immediately confiscated, and you will be slapped with a massive on-the-spot fine. The rule this winter is incredibly simple: leave all vapes, pods, and electronic smoking devices at home so you can get to your resort without a massive customs fine.
2. The SJD Airport “Shark Tank”
After you clear customs, you have to navigate the most notorious hallway in Los Cabos: the timeshare presentation gauntlet, affectionately known by veteran travelers as the “Shark Tank.”
As you walk toward the exit doors, aggressive timeshare salesmen dressed to look exactly like official airport staff or transportation coordinators will try to flag you down, offering free tequila, excursions, or taxi rides to your resort. Do not make eye contact, and do not politely engage. Keep walking straight through the double glass doors to the outdoor transportation zone, where your pre-booked, authorized driver will be waiting.

3. Deceptive Ocean Undertows Right Off Your Resort
One of the biggest shocks for first-time Cabo visitors is discovering that the pristine beach directly in front of their luxury resort might be incredibly dangerous.
You must understand the geography of the peninsula. Resorts facing the Pacific Ocean—from Land’s End up toward Diamante—sit on beaches that are strictly unswimmable due to incredibly violent rogue waves and life-threatening undertows. Even on the calmer Sea of Cortez side along the Tourist Corridor, winter swells can make swimming dangerous. You must obey the colored beach flags posted by resort lifeguards: green means safe, yellow means caution, and red or black means absolutely no swimming. If you want a guaranteed safe beach day, book a resort on Medano Beach or Chileno Bay.

4. Hidden Upcharges at “Fully” All-Inclusive Resorts
During the winter high season, resorts aggressively try to maximize their revenue per guest. Just because you booked an “all-inclusive” package does not mean your wallet can stay in the room.
Many travelers are caught off guard by the premium upcharges layered throughout the property. That gorgeous Bali bed or private cabana by the main pool? It often requires a daily rental fee or a minimum bottle service spend. Furthermore, while standard drinks and buffets are included, many resorts charge massive premiums for top-shelf liquor, specialty cuts of steak, or exclusive dining experiences on the sand. Read the fine print of your resort’s specific all-inclusive tier so you aren’t shocked by your checkout bill.
5. Securing High-Season Resort Dining Reservations
During the off-season, you can easily walk into your resort’s Italian or Japanese specialty restaurant at 7:00 PM and grab a table. During the winter, that is physically impossible.
With resorts operating at near 100% capacity from December through April, the on-site specialty restaurants are pushed to the absolute limit. If your resort allows you to book dinner reservations via their app before you arrive, do it immediately. If not, making reservations for your entire stay should be your absolute first priority the minute you check in at the front desk. The same rule applies for off-resort hotspots like Flora Farms or Sunset Monalisa—if you don’t book weeks in advance, you will not get a table.

6. The “Cash is Still King” Reality for Resort Tipping
Mexico recently passed a Digital Economy Law mandating that businesses accept electronic payments. But when it comes to the incredible staff making your resort vacation possible, cash is still the absolute king.
While tipping is technically included in many all-inclusive packages, leaving a few dollars for your bartender, poolside waiter, or daily housekeeping staff guarantees you receive spectacular, priority service during the busy winter months. Bring a stack of small denomination US dollars (ones and fives) or Mexican pesos. The resort staff works incredibly hard during the high season, and cash tips go directly into their pockets without heavy taxation or bank processing fees.
7. Dengue Fever Prevention on Off-Resort Excursions
Like any tropical destination, mosquitoes are a reality, and Dengue fever is an ongoing regional concern.
If you spend your entire trip inside the luxury mega-resort bubble, your risk is incredibly low—major hospitality properties run aggressive thermal fogging operations every single day to kill mosquitoes. However, if you venture outside the resort to hike in the desert, ride ATVs, or eat dinner in the foothills at dusk, you need to protect yourself. Pack an EPA-registered insect repellent containing DEET or Picaridin, and apply it over your sunscreen before you head out for any off-property excursions.

8. Using the Right ATMs When Leaving the Resort Bubble
Cabo San Lucas and San José del Cabo are incredibly safe to walk at night, but the most common crime tourists face when leaving the resort is financial.
If you need extra cash for a boat tour or a night out in the Marina, avoid using standalone ATMs located directly on the street or tucked into dark convenience stores, as they are highly prone to electronic skimming devices. Instead, plan ahead and use the secure ATM located right inside your resort’s lobby. If you are already in town, only use ATMs securely located inside official, brightly lit bank lobbies (like Banorte or Santander) or inside major shopping centers like Puerto Paraíso.
