December is one of the most popular times of year to visit Los Cabos, but your experience depends heavily on when in the month you arrive. I typically divide the month into two distinct periods: the calm, high-value window of early December and the high-energy, high-cost festive peak that runs from Christmas through New Year’s Day. If you want winter sun without the maximum crowd levels, aim for the first ten days of the month.
Early December vs. Holiday Week
There is a sharp contrast in how Cabo feels as the month progresses. Understanding this is key to setting your expectations for both your budget and the overall atmosphere.
- Early December: This is a hidden gem for travel. Crowds are thinner, restaurant reservations are easier to secure, and hotel rates are often lower than they will be just two weeks later. The weather is already excellent, and the water is still relatively warm from the autumn.
- Christmas and New Year’s: This is the busiest and most expensive stretch of the winter season. Expect peak pricing at resorts and a high-energy “see and be seen” vibe in the marina and on Medano Beach. Everything from airport shuttles to popular dinner spots will be operating at maximum capacity.
December Weather and What to Pack
The humidity is much lower in December than in the late summer and fall, so the air generally feels drier and more comfortable. It is arguably the most pleasant time of year for outdoor dining and exploring the desert landscape.
- Typical Temperatures: Daytime highs usually hover in the upper 70s to low 80s (25°C to 28°C). Nighttime temperatures fall into the low 60s (15°C to 17°C).
- Rainfall: Rain is uncommon in December. You can generally count on clear skies for the duration of your trip.
- Packing List: I recommend bringing swimsuits and sun protection for the day, but you will definitely need light layers for the evening. A light sweater or jacket is essential for dinner by the water. If you plan on long snorkeling sessions, a rash guard or light wetsuit top is a smart addition, especially for kids.
Whale Watching: The Start of the Season
December marks the start of whale watching season in Los Cabos. While sightings are possible early in the month, the official tour season commonly begins around December 15. I like to remind travelers that December is just the beginning; the heaviest whale activity typically occurs later in January and February.
- Humpback Whales: These are the whales most travelers associate with Cabo tours. They are active, known for breaching, and are the primary species you will see in the local waters.
- Gray Whales: While Humpbacks are the main attraction near Cabo, Gray whales are more famously tied to the shallow lagoons in the northern parts of Baja.
- Boat Conditions: I usually suggest booking morning whale tours. The sea is often calmer in the morning, which makes for a more comfortable boat ride than in the windier afternoons.
Best Beaches for Swimming and Safety
Not all beaches in Cabo are safe for swimming, regardless of the water temperature. The ocean is usually still swimmable in December, especially early in the month, but many travelers find it feels brisk for long snorkeling sessions by late December as surface temperatures drop into the mid-70s.
- Medano Beach: This is the most popular swimmable beach in Cabo San Lucas. It is protected and ideal for families.
- Chileno and Santa Maria: Located along the Corridor, these are excellent for snorkeling and usually offer calm, clear water.
- Pacific Side Warning: Many Pacific-facing beaches have dangerous surf and strong undertows. Only swim where conditions are clearly designated as safe and always follow local warning flags.
Holiday Reservation Checklist
If you are traveling between December 20 and January 2, your booking strategy must be proactive. I recommend booking your primary activities as soon as your lodging is confirmed.
- Festive Dinners: Christmas Eve and New Year’s Eve dinners at popular spots book up months in advance. Many upper-end resorts offer special prix-fixe menus which may require a separate fee from your room rate.
- New Year’s Eve Fireworks: Medano Beach is the central hub for the midnight fireworks display. If you want a view, book a beachfront dinner or a spot at a Medano beach club well ahead of time.
- Airport Transportation: The ground transportation area at Cabo airport can be hectic. Pre-booking a private transfer is the best way to avoid the stress of the “shark tank” arrival area.
- Whale Tours: Popular boats fill up fast during the holiday week. Book your spot before you leave home.
Dining and Grocery Strategy
For those staying in villas or condos, timing is everything. Grocery stores and warehouse clubs get extremely busy right before Christmas and New Year’s. I suggest doing your major shopping early in the week to avoid the last-minute holiday rush. Also, be aware that while resort restaurants stay fully active, some smaller local businesses may operate with reduced hours on December 25 and January 1.
Is December Right for You?
- Best For: Families on school break, holiday travelers who love a festive atmosphere, and anyone looking for the start of whale season and comfortable daytime weather.
- Less Ideal For: Travelers looking for the absolute quietest version of Cabo, bargain hunters traveling during Christmas week, or those who want the warmest possible ocean water.
Cabo in December FAQ
Is December a good month for swimming in Cabo?
Yes, the water is generally between 72°F and 75°F. It is refreshing but comfortable for most, though you might want a heated pool for the cooler evenings.
Is early December much cheaper than Christmas week?
Usually, yes. The price hike typically begins around December 18 to 20. Before that, you can often find much better rates on lodging.
When do the whales arrive?
The official tour season starts December 15, though early arrivals often appear in the weeks leading up to that date.
Do I need dinner reservations?
For the holiday week, absolutely. For early December, you can be more spontaneous, but I still suggest booking your “must-visit” restaurants a few days out.
Overall, December is a very comfortable time for a winter getaway. Whether you want the quiet of the early month or the electric atmosphere of New Year’s Eve, it remains one of my top picks for a Mexican escape.
