Visiting Cabo In December: 5 Most Important Things Travelers Need To Know

Share The Article

Landing in Cabo in December can feel like hitting the jackpot and the final boss level of trip planning at the same time. The weather is dreamy, whales are arriving, Christmas lights are sparkling over the marina… and almost everything is sold out if you don’t plan ahead.

We at The Cabo Sun spend a lot of time tracking winter in Los Cabos, from safety operations to Blue Flag beach upgrades and new tools like our Ultimate Cabo Trip Planner and Cabo Resort Finder, so we’ve pulled together the five big things December visitors really need to know—beyond the glossy resort photos.

1. Early December And Christmas Week Are Basically Two Different Destinations

First, a reality check: December is split into two very different seasons.

• Dec 1–15: usually calmer, with better room availability and more reasonable rates. You still get classic winter-in-Los-Cabos sunshine without the full holiday crush.
• Dec 16–New Year’s: this is ultra-peak. Many resorts jump to their highest prices of the year, and the most popular places can sell out months in advance.

We see it every year in our inbox: a reader decides in late November that “maybe we should do Christmas in Cabo” and is shocked at what’s left—if anything—under a certain budget.

If you’re still flexible:

• Use our Ultimate Cabo Trip Planner to compare December to shoulder months like November and January for weather vs. crowds.
• If you love the idea of holiday vibes without holiday prices, aim for the first two weeks of December and fly home before the big Christmas spike hits.

As one of our readers recently told us, “Once we did Christmas week without planning ahead, we learned our lesson. Now we treat mid-December like gold.”

2. December Weather Is Gorgeous — But You Need A “Dual Wardrobe”

On paper, December looks perfect: warm, dry days and very little rain compared to late summer. In practice, there’s one thing that still surprises first-timers: Day and night feel like two different seasons.

• Daytime: Mid- to upper-70s to low-80s Fahrenheit, ideal for pool time, golf, boat tours, and beach walks. Sun is still strong, so sunscreen and hats are non-negotiable.
• Evening: Once the sun drops, the desert cools fast. You’ll want a light sweater, wrap, or thin jacket—especially if you’re dining near the ocean.

Water temps are generally swimmable, but cooler than fall. Many travelers are comfortable in a swimsuit; if you run cold or plan long snorkel sessions, a light rash guard or shorty wetsuit helps.

Our “3–2–1 December Rule” (Cabo Sun exclusive tip):

• 3 layers: swimsuit / daytime outfit / one warm layer you’re not afraid to wear every night.
• 2 pairs of shoes: sandals plus something closed-toe for cooler evenings and ATV tours.
• 1 “just in case” item: compact jacket or shawl that lives in your day bag for sunset.

You won’t see that combo on packing lists elsewhere, but it’s what we actually use on the ground.

3. Ocean, Whales, And Water Tours: Mornings Win In December

December is when whale season really kicks off in Los Cabos. Whale-watching officially runs from mid-December into spring, with action building as more humpbacks arrive.

A few need-to-know points for this month:

• Book whale tours for the morning. Seasonal northerly winds can pick up later in the day and make the water choppier. Mornings usually mean calmer seas and better visibility—especially important if you’re prone to seasickness.
• Know your bucket-list: Whale watching happens right off Cabo San Lucas and the tourist corridor. Whale shark swims, on the other hand, are based out of La Paz, a few hours away and usually sold as full-day excursions.

And then there’s beach safety, which we’re constantly reminding readers about. Cabo sits where the Pacific Ocean meets the Sea of Cortez—beautiful but powerful water.

Before you book a resort or sprint into the waves:

• Check our guide on whether your Cabo resort’s beach is actually swimmable so you don’t arrive to red-flag Pacific surf you can’t enter.
• Prioritize Blue Flag–certified beaches like Chileno, Santa María, and Palmilla if you want safe, well-managed spots for swimming and snorkeling.
• Learn the beach flag colors before you go; they trump everything you see on Instagram. Green/yellow means “maybe,” red and black mean “nope.”

4. Airport “Shark Tank,” Uber & Holiday Traffic

If you’ve read our coverage of Uber and taxis in Los Cabos, you already know transportation has its own politics here. December’s heavy traffic just amplifies it.

Here’s the simple version for holiday travelers:

• From the airport: We still recommend pre-booking a licensed transfer rather than trying to wing it with apps on arrival. Inside the terminal you’ll walk through what regulars call the “shark tank” of timeshare pitches and transport offers—just keep walking until you’re outside to meet your confirmed driver.
• Around town: Once you’re in Cabo San Lucas, San José del Cabo, or the Corridor, Uber is generally available and often much cheaper than taxis. That said, expect longer wait times and occasional surge pricing during peak Christmas and New Year’s dates.

For December specifically:

• Build extra time into any airport run, especially on Saturdays and around New Year’s Eve.
• If you’re staying in the Corridor and planning big nights out in downtown Cabo, consider doing your main late-night party on a non-holiday night—traffic and prices are usually a bit kinder.

5. Reservations, Events, And Picking Your Cabo Zone

December is when the spontaneous walk-up culture mostly disappears.

Restaurants & activities

Popular farm-to-table spots in San José, marina-view restaurants in Cabo San Lucas, and top-rated excursions can book out weeks in advance for holiday dates. We hear from a lot of readers who arrive expecting to “just see what we feel like” and end up eating at odd hours or grabbing whatever’s left.

Our advice:

• Secure dinner reservations for your must-do spots as early as you can—especially between Dec 20 and Jan 2.
• Book at least one “anchor” experience early (whale watching, sunset sail, or off-road adventure), then fill in the rest once you’re on the ground.

Events & New Year’s Eve

New Year’s Eve in Cabo centers around fireworks over Médano Beach and big parties at clubs and beach clubs. Tickets and table packages often go on sale in the fall and can sell out, especially for waterfront views.

Where to stay in December

With so much going on, choosing the right zone matters more than usual:

• Cabo San Lucas: high-energy, very busy in December; great for nightlife and being near Médano Beach.
• San José del Cabo: more relaxed, artsy, with a strong dining scene and calmer holiday vibe.
• The Corridor: luxury resorts strung between the two towns; best if you’re happy to mostly stay on-property and Uber out for specific plans.

If you’re not sure which fits your style, our “Which Area Of Los Cabos Should I Stay In?” vibe tool and Cabo Resort Finder can narrow it down in seconds based on your budget and travel style.

Finally, don’t forget the little on-the-ground details that define December 2025 specifically: stronger enforcement of vendor rules on Médano Beach, ongoing safety operations for winter visitors, and record numbers of Blue Flag beaches all make the experience a little more organized—and a lot safer—than it used to be.
