Los Cabos in December: Weather, Whales & Holiday Tips
Is Los Cabos Good in December?
Yes — Los Cabos in December is one of the safest winter-sun bets in Mexico if you want dry Baja weather, resort polish, whale-watching potential, and a festive holiday atmosphere. The desert heat has eased, rain is rare, the sea is still warm enough for protected swimming beaches, and the destination is fully awake after the slower fall months.
The catch is price. December is not a bargain month in Cabo. Early December can still feel manageable, but Christmas week and New Year’s bring peak-season hotel rates, booked restaurants, crowded marina tours, and flights that need early planning.
Start with Mexico in December if you are still comparing destinations across the country. Use this guide if Los Cabos is already on your shortlist and you need the practical December answer: weather, whales, beaches, resorts, Christmas week, New Year’s, and whether January might be smarter.
30-Second Answer
| Question | Short answer |
|---|---|
| Is December good for Los Cabos? | Yes. It is one of the best months for dry weather, resort trips, and opening whale season. |
| Biggest upside | Sunny days, low rain risk, cooler evenings, and holiday energy. |
| Biggest downside | Peak prices from Christmas through New Year’s. |
| Best dates | Dec 1-18 for easier logistics; Dec 24-Jan 1 for holiday atmosphere. |
| Best base | Medano Beach, the Corridor, or San José del Cabo. |
| Worst fit | Travelers chasing quiet beaches, low prices, or guaranteed peak whale activity. |
Go in December if you want Cabo in polished winter mode and can book early.
Choose January if whales matter more than holiday atmosphere, or November if you want warmer water and better value before peak season hits.
Los Cabos Weather in December
December is dry season in Los Cabos. Expect bright days, little rain, lower humidity than summer, and cool evenings that feel different from the tropical parts of Mexico.
| Weather factor | December in Los Cabos |
|---|---|
| Daytime temperature | 25-28°C / 77-82°F |
| Night temperature | 16-19°C / 61-66°F |
| Rain | Very low, often 0-1 rainy days |
| Humidity | Low to moderate |
| Sea temperature | 22-25°C / 72-77°F |
| Hurricane risk | Very low |
This is ideal weather for beach clubs, boat tours, golf, desert ATV trips, sunset dinners, and walking around San José del Cabo. It is cooler than August through October, but most travelers find December more comfortable because the heat is no longer heavy.
Pack normal beach clothes, sunscreen, sunglasses, a hat, and one light layer for evenings. If you are staying on the Pacific side, booking sunset cruises, or eating outdoors in San José del Cabo, that layer matters more than it would in Cancún or Puerto Vallarta.
Can You Swim in Los Cabos in December?
Yes, but Cabo always comes with the same important rule: not every beautiful beach is safe for swimming. December has good beach weather, but Pacific-facing beaches can still have strong surf, steep drop-offs, and currents.
Best December swimming and snorkeling areas:
- Medano Beach: The easiest swimming beach in Cabo San Lucas, with restaurants, boat access, and the liveliest scene.
- Chileno Bay: Clear water, snorkeling, and a better choice if you want a calmer beach day away from the marina.
- Santa Maria Bay: Good snorkeling and protected water when conditions are calm.
- Palmilla Beach: Family-friendly and usually easier for swimming than exposed Pacific beaches.
Be careful at Divorce Beach, the Pacific side of Land’s End, and many resort beaches along the open coast. If a hotel says the beach is not swimmable, believe it. Choose the resort for views, pools, restaurants, and service — not because the sand automatically means safe ocean swimming.
Whale Watching in Los Cabos in December
December is the opening act of whale season in Los Cabos. Humpbacks begin arriving in the waters around Cabo San Lucas, and gray whales start reaching the wider Baja California Sur lagoons. You can absolutely book a whale-watching tour in December, especially later in the month.
The honest expectation:
- Early December: Possible sightings, but not peak reliability.
- Mid December: Better odds as more humpbacks arrive.
- Late December: Good opening-season whale watching, especially on active tour routes.
- January-March: Stronger peak season if whales are the main reason for the trip.
For a deeper countrywide comparison, use the Whale Watching in Mexico guide. Los Cabos is one of the easiest whale destinations because tours depart from the marina and fit neatly into a resort itinerary. If you want the classic gray-whale lagoon experience, plan a longer Baja route through La Paz, Magdalena Bay, Loreto, or Guerrero Negro.
Where to Stay in December
Where you stay matters more in December because traffic, dinner reservations, tour pickups, and beach access all become more competitive.
| Area | Best for | December note |
|---|---|---|
| Medano Beach / Cabo San Lucas | Beach access, nightlife, marina tours, first-time visitors | Most convenient, busiest, expensive near NYE |
| The Corridor | Resorts, pools, golf, ocean views, couples | Check whether the beach is swimmable before booking |
| San José del Cabo | Art Walk, restaurants, quieter stays, couples | Great for atmosphere; farther from Cabo marina tours |
| Pacific side / Todos Santos side | Surf, design hotels, slower trips | Beautiful, but ocean swimming is often unsafe |
Choose Medano Beach if you want walkable beach days and easy boat tours. Choose the Corridor if the resort itself is the point. Choose San José del Cabo if you want a calmer holiday base with galleries, restaurants, and a more polished evening rhythm.

Christmas and New Year’s in Los Cabos
December has two personalities in Cabo.
December 1-18 is the smarter window for most travelers: dry weather, active restaurants, whale tours beginning, and easier hotel availability than the holiday rush.
December 22-January 2 is peak holiday Cabo. Resorts fill, New Year’s dinners sell out, beach clubs charge premium rates, and minimum stays become common. If you want the energy, it can be fantastic. If you want a flexible low-stress trip, it can feel expensive and rigid.
Book early for:
- Ocean-view rooms and family suites
- All-inclusive resorts during Christmas week
- NYE dinners and rooftop parties
- Private airport transfers
- Whale tours, sunset cruises, and Cabo Pulmo day trips
- Popular restaurants in San José del Cabo and Cabo San Lucas
A good rule: book hotels 4-6 months ahead for early December and 6-10 months ahead for Christmas or New Year’s. For luxury resorts with limited inventory, start even earlier.
Best Things to Do in Los Cabos in December
December is strong because almost every classic Cabo activity works.
Take a Land’s End Boat Tour
Clearer winter weather is perfect for El Arco, Lovers Beach views, sea lions, and a short glass-bottom boat ride from the marina. Go in the morning for calmer water and better light.
Book a Whale-Watching Tour
Late December is better than early December, but even opening-season tours are worth considering if whales are a bonus rather than the entire trip.
Spend a Day at Chileno or Santa Maria
These are better choices than many resort beaches if swimming and snorkeling matter. Bring reef-safe sunscreen and check conditions before entering.
Explore San José del Cabo
The Art District feels especially good in December evenings. Restaurants, galleries, and the Thursday Art Walk give the trip a different rhythm from Cabo San Lucas nightlife.
Go Into the Desert
December’s cooler temperatures make ATV trips, camel rides, horseback riding, and canyon hikes easier than in summer. Morning tours are still the most comfortable.
Consider Cabo Pulmo Carefully
Cabo Pulmo can be excellent, but it is a long day from many resorts and conditions vary. If snorkeling or diving there is a priority, build flexibility into the itinerary rather than treating it like a guaranteed beach-club day.
Los Cabos in December vs November vs January
| Factor | November | December | January |
|---|---|---|---|
| Weather | Warm, dry, great value | Dry, sunny, cooler evenings | Dry, sunny, cooler evenings |
| Prices | Lower than winter peak | Highest around holidays | Lower after Jan 3 than NYE week |
| Whales | Early/bonus sightings | Season opens properly | Stronger whale season |
| Crowds | Moderate, Thanksgiving spike | High near Christmas/NYE | Moderate after holidays |
| Best for | Value + warm water | Holiday resort trip | Whales + calmer logistics |
Choose November for better value, warmer water, and fewer holiday constraints.
Choose December for Christmas atmosphere, New Year’s energy, resort polish, and opening whale season.
Choose January if whale watching is the priority and you can travel after the holiday rush.
Who Should Visit Los Cabos in December?
December is a strong fit for:
- Couples who want polished resorts and winter sun
- Families booking a Christmas beach trip early
- Travelers who want dry weather without Caribbean sargassum worries
- First-time Cabo visitors who want the destination in full swing
- Whale watchers who are happy with opening-season sightings
- Golf, spa, food, and resort-focused trips
It is a weaker fit for:
- Budget travelers hoping for low hotel rates
- People who dislike reservations and fixed holiday logistics
- Travelers who need guaranteed peak whale encounters
- Anyone expecting every beach in Cabo to be swimmable
- Last-minute Christmas or New Year’s planners
Suggested 5-Day December Itinerary
Day 1: Arrive, settle into Cabo San Lucas or San José del Cabo, sunset dinner.
Day 2: Land’s End boat tour, Medano Beach, marina dinner.
Day 3: Whale-watching tour in the morning, San José del Cabo Art District in the evening.
Day 4: Chileno Bay or Santa Maria snorkeling, resort pool afternoon.
Day 5: Desert adventure, spa, or a slower beach-club day before departure.
If you have a week, add Todos Santos, Cabo Pulmo, or a La Paz extension for whale sharks and Balandra. That wider Baja route is one of the best December wildlife combinations in Mexico.
Final Take: Is December Worth It?
Los Cabos in December is worth it if you want dry Baja weather, winter resort energy, early whale watching, and a polished holiday trip — and you are comfortable paying peak-season prices.
For the best balance, travel in the first half of December. For Christmas or New Year’s, treat the trip like a high-demand event and book early. For stronger whale odds and fewer holiday logistics, shift to January.
