December is one of the most attractive months to visit Cancun. While much of the world is dealing with cold weather, here you get warm days, festive nights, and a full calendar of tours, shows, and day trips perfectly suited to the season.
Below you’ll find what December is like in Cancun and the best things to do during this month, from beaches and ruins to Christmas lights and New Year’s Eve parties.
Cancun in December: Weather, Crowds and Atmosphere
December brings some of the most comfortable weather of the year. Daytime temperatures usually sit around 26–28°C (79–82°F), with evenings dropping to the low 20s°C (low 70s°F). Rainy season has just ended, humidity is lower, and the Caribbean Sea stays warm at about 26°C (79°F), so you can swim all day without getting cold.
It’s also the beginning of high season. Early December is lively but manageable; from Christmas through New Year’s, the city fills up with visitors and prices for hotels, flights, and activities rise. Those who arrive earlier in the month find easier reservations and slightly fewer crowds while still enjoying the same good weather.

The atmosphere is very festive. Cancun decorates its malls and main avenues with Christmas lights and trees, neighborhoods such as Puerto Juárez host events like “Santa comes from the sea” (Santa arriving on a jet ski), Malecon Tajamar turns on a December-long light show, and there are traditional Mexican posadas both in town and at parks such as Xcaret. Around late November and early December, the Riviera Maya Jazz Festival in nearby Playa del Carmen also draws music lovers to the area.
Best Outdoor Things to Do in Cancun in December
Enjoy the beaches and warm Caribbean water
In December you can spend Christmas week literally on the sand. With sunny days and mild evenings, it’s comfortable to sunbathe, walk the shoreline, and swim even on the morning of December 25. Calm seas and minimal rain make this one of the best months for pure beach time, whether you stay in the Hotel Zone or visit quieter stretches like Playa Delfines, Playa Langosta, or more secluded spots up the coast.

At Royal Garrafon Natural Reef Park, you can kayak, snorkel, zipline over the sea, or simply relax at the beach club with Caribbean views.

If you’re willing to travel farther, Cozumel is a classic December excursion: ferries or organized tours take you to an island known for world–class reefs, white-sand beaches, and the small town of San Miguel, decorated for the holidays. hellotickets.com+1
Swim in cenotes and underground rivers
December’s warm, dry weather is perfect for visiting cenotes (natural sinkholes) and underground rivers:
-
Rio Secreto and other cave systems let you walk and float through crystal-clear water surrounded by stalactites and stalagmites.
-
Open cenotes near Cancun and along the highway to Tulum are ideal for swimming, cliff-jumping, or relaxed floating away from the beach crowds.
Many day tours combine cenotes with zip lines, ATVs and lunch, taking advantage of the cooler, less humid conditions of the season.

Visit Mayan ruins in cooler temperatures
December is one of the most comfortable months to tour archaeological sites:
-
Chichén Itzá: full–day excursions typically include the main pyramid of Kukulkán, other temple complexes, time in a colonial town like Valladolid, and a swim in a nearby cenote.
-
Tulum: ruins on a cliff above the sea, often paired with a cenote stop or snorkeling in nearby reefs.
-
Cobá and other less-visited sites offer quieter jungle surroundings, still with impressive pyramids and causeways.
The sun is strong, but the heat is less intense than in spring and summer, so walking around the ruins is much more pleasant.

Xplor focuses on zip lines, amphibious vehicles, cave rivers and adventure circuits that feel cooler in the December air.

Xel-Há, Ventura Park and other multi-activity parks combine slides, lazy rivers, snorkeling, zip lines and kids’ areas—ideal for families traveling during school holidays.
