Mexico › Los Cabos › Cabo in December

December is one of the most popular months in Los Cabos, but it is a tale of two very different seasons. The first half of the month is a hidden gem with manageable crowds and great value, while the final ten days are a high-energy, high-cost festive sprint. Whether you are coming for the winter sun or the start of the whale migration, understanding the mid-month shift is the key to a successful trip.
Is December a Good Time to Visit Cabo?
I usually tell people that if you can travel before December 18, it is one of the best times of the year. If you are coming for Christmas or New Year, it is fantastic for the atmosphere, but you must be prepared for peak crowds and pricing.
- Best for: Whale watching, festive holiday atmosphere, and escaping the northern winter.
- Great fit for: Families on school break and travelers who enjoy a “see and be seen” vibe.
- Less ideal for: Travelers looking for the warmest ocean water or those on a strict budget during the holidays.
- The Verdict: It is the ultimate winter escape, provided you book your favorite restaurants and activities weeks in advance.
December Weather: Clear Skies and Desert Chills
The humidity of summer is a distant memory by December. The air is crisp, and the sky is almost always a clear, bright blue. However, do not let the “Mexico” label fool you; it gets cool once the sun drops.
- Daytime: Expect highs around 78°F to 81°F (25°C to 27°C). It is perfect for walking the marina or playing a round of golf.
- Evening: Temperatures dip to 60°F or 62°F (15°C to 17°C). When the wind picks up off the Pacific, it can feel even cooler.
- Rainfall: Rain is extremely rare in December. You can usually count on dry weather for your entire stay.
- The Air: The desert air is very dry this month. I always suggest bringing extra moisturizer and staying hydrated.
Can You Swim in Cabo in December?
Swimming is still very much on the menu, but the water is losing its summer heat. The ocean temperature typically averages 73°F to 75°F (23°C to 24°C). It is refreshing, but if you are used to the bathtub-warm water of the Caribbean, it might feel a bit brisk for long snorkeling sessions.
Ocean Swimming: Stick to the protected coves. Medano Beach is the best for a casual dip, while Chileno Bay remains the top choice for snorkeling. Stay away from the Pacific-facing beaches; the currents are notoriously dangerous and not for swimming.
Pool Swimming: In December, a heated pool is highly recommended. While the afternoons are warm enough for a dip, unheated pools start to feel quite cold by the middle of the month, especially for children.
The Arrival of the Whales
December marks the official start of whale watching season in Los Cabos. While you might see a few early arrivals in late November, the licensed tours generally begin around December 15.
By the end of the month, the Humpbacks are usually out in force. I suggest booking morning tours as the afternoon winds can make the water choppy, which makes spotting whales more difficult and the boat ride much bumpier. If you are staying at a beachfront resort in the Corridor, keep your binoculars handy; you can often see them breaching from your balcony.
December Crowds and the Festive Peak
I divide December into two distinct tiers for planning and budgeting.
- Early December: From the start of the month until about December 18, Cabo is surprisingly relaxed. You can often find better hotel rates and last-minute dinner reservations.
- The Festive Peak: From roughly December 20 through New Year’s Day, Cabo is at maximum capacity. This is the most expensive time of the year to visit.
- Reservations: If you are visiting during Christmas week, you must book your airport transfer and “must-do” restaurants like Flora Farms or Edith’s at least a month in advance.
Best Areas to Stay in December
- Cabo San Lucas: Best for the holiday energy. Medano Beach is the hub for New Year’s Eve fireworks and beachfront celebrations.
- The Tourist Corridor: Best for those who want a high-end resort experience with space to breathe. This is where you find the best whale watching views from the shore.
- San José del Cabo: Best for a more traditional Mexican Christmas. The town plaza is beautifully decorated, and the Art Walk is a highlight for early December travelers.
What to Pack for December
- Proper Evening Layers: A real jacket, a light fleece, or a heavy sweater. You will absolutely need it for dinner by the water or a sunset cruise.
- Rash Guard or Light Wetsuit: If you plan on snorkeling for more than twenty minutes, a bit of insulation makes a big difference in the December water.
- Sunscreen: The winter sun is deceptive. The cool breeze makes you feel like you aren’t burning, but the UV index remains high.
- Closed-toe Shoes: Essential for the cool evenings and for exploring the desert terrain.
Common December Mistakes
- Packing Only Summer Clothes: I see it every year; tourists buying expensive hoodies at the marina because they didn’t realize how cold the desert gets at night.
- Ignoring the “Shark Tank”: The arrival area at the airport is chaotic in December. Do not try to find transportation on the fly. Pre-book a private transfer.
- Missing the Fireworks: The New Year’s Eve fireworks over Medano Beach are spectacular. If you aren’t staying on the beach, book a dinner table with a view months ahead of time.
- Expecting “Bath Water”: The ocean is cooling down. If you want tropical warmth, you should have come in October.
