In December, Cancun sees highs around 82 °F, lows near 70 °F and a sea temperature close to 81 °F. It is the start of the dry season, with little rain and an occasional “norte” that brings wind and one cool day. It is a good month to travel, especially for ruins and cenotes, but there are really two Decembers: the calmer first half, and the holiday stretch when the city fills up and rates climb.
What is the weather like in Cancun in December?
December is dry and mild. Days hover near 82 °F with plenty of sun, and nights dip to about 70 °F, cool enough that a long-sleeve shirt or thin jacket feels good at an outdoor dinner. The sea, around 81 °F, is still comfortable for swimming, and because the heat has eased, walking around the city or touring archaeological sites takes far less out of you than it does in summer.
The typical weather event of the month is the “norte”, a cold front that sweeps in from the Gulf and leaves a day or two of wind, clouds and lower temperatures. They do not ruin a trip, but they change the plan: good days for museums, markets or a massage, less so for hours on the beach. It also gets dark early, around six in the evening. For your suitcase, see what to pack for Cancun.
Is December a good time to visit Cancun?
Yes, and it is one of the months with the best balance of weather and atmosphere. Rain is scarce, sargassum is usually low and the Caribbean beaches look their best, although sargassum varies from year to year, so check the report before you go. What changes noticeably over the course of the month is the crowd level, and with it the price. To see how it fits with the rest of the year, read the best time to visit Cancun.
High season starts in the middle of the month and prices rise as Christmas approaches. The first half is calmer: you have more room to choose a hotel room, attractions are less crowded and you can still book with only a few days' notice. From the week of the 20th everything changes, with full flights, lines at excursions and dinners by reservation. If your dates are flexible, travel earlier; if not, read our guide to Christmas and New Year in Cancun.
What can you do in Cancun in December?
December is the ideal month for what wears you out in summer: ruins and cenotes. Chichén Itzá, Tulum and Cobá are far easier to walk in the milder heat, and cenotes stay cool all year, so a dip after the hike is still a reward. Chichén Itzá is about two and a half hours by car from downtown; leave early and confirm the current hours. The details are in Chichén Itzá from Cancun.
For beach days, the Hotel Zone and Puerto Cancún work well, and the ferry to Isla Mujeres, which leaves from Puerto Juárez, makes a good half-day trip when the sea is calm. Downtown offers markets, sunset strolls through the Parque de las Palapas and outdoor dinners in pleasant temperatures. A sensible three-day plan mixes a ruins day, a beach or island day and a slow day.
- Ruins at Chichén Itzá, Tulum or Cobá, with an early start.
- Cenotes along the road to Tulum or Valladolid.
- The ferry to Isla Mujeres on a calm-sea day.
- A walk through downtown and an outdoor dinner.
Which plans are better left for another time of year?
Swimming with whale sharks is not possible in December; their season is concentrated in the summer months. If that is your dream, plan another month. It is also unwise to bet everything on a single beach day: if a norte arrives, the sea gets choppy, the wind cools things down and some boat trips may be rescheduled or canceled. Leave a spare day in your itinerary and confirm with the operator the day before.
Dinners and excursions for the week of December 20 to 31 should not be left to the last minute either, nor should the airport transfer. And remember that it gets dark early: if you leave the ruins late, the drive back happens after sunset, so an early start solves most problems. If you are torn between December and another month, compare with Cancun in January, a bit cooler and quieter after Three Kings Day.
Where should you stay in Cancun in December?
Choosing where to sleep in December means deciding what kind of trip you want. The Hotel Zone puts you steps from the beach, but also brings the year's highest rates and heaviest traffic. Downtown gives you local life, the bus terminal and restaurants on foot, with the beach about 15 minutes away. Mezcal Boutique Hotel is at Calle Mero 12, on the corner of Avenida Nader, about 20 minutes by car from the airport.
It has 25 rooms, an urban-jungle garden with a cenote-style pool and a koi pond, a 24-hour front desk, free wifi and free parking for guests. On a windy day, the Mangroove Spa and the temazcal make a good plan. It is not all-inclusive: the rate covers lodging only. If you know your dates, book direct for the best available rate, and in December it pays to do it early.
