Cancún by month
Cancún in December
Cancún in December: 82°F highs, 69°F lows, dry season in full swing · the first two weeks of december are quiet and affordable, with wide-open beaches and mid-tier hotel rates—one of the year's true shoulder windows. Crowds, hotel prices, when to book, and what's worth doing.
December splits into two seasons: the first half is one of Cancún's secret sweet spots—warm, dry, nearly empty beaches, and shoulder pricing—while the second half explodes into peak-season chaos as Christmas and New Year's visitors flood the Hotel Zone. Expect perfect beach weather all month: low-80s, dry skies, light Caribbean breeze, minimal sargassum. If you're booking the Christmas fortnight, do it six months out and brace for top-dollar rates and minimum-stay requirements; if you're coming early December, you'll have Playa Norte and the reefs nearly to yourself at half the price.

Temperature
82°F highs, 69°F lows—the coolest, most comfortable month of the year with steady sun

Rain
Dry season in full swing—virtually no rain, low humidity, blue skies day after day
Crowds & prices
The first two weeks of December are quiet and affordable, with wide-open beaches and mid-tier hotel rates—one of the year's true shoulder windows. Around December 18 the switch flips: crowds surge, prices jump to top-of-market ($$$–$$$$), and many all-inclusives impose minimum-stay rules and sell out entirely. Christmas week and New Year's are Cancún's absolute peak; expect packed beaches, reservation waits, and little availability unless you booked half a year ago. If you want December weather without December madness, stay in the first half of the month.
When to book
Christmas and New Year's week: book flights and hotels six months out—August or September for late December. Early December (1st–17th): two to three months is plenty, and you'll find shoulder pricing and good availability across the Hotel Zone, Playa, and Isla Mujeres.
Our getting-there guide covers flights to Cancún plus a cheapest-fare-by-month table to sanity-check December flight prices.
What to do
What December is made for.
On the calendar
- Guadalupe Day (December 12) with processions and celebrations
- Christmas posadas throughout the month
- New Year's Eve beach parties and fireworks in the Hotel Zone
Pack for December
- Reef-safe sunscreen—December sun is strong even if the air feels mild
- Light long sleeves for occasional breezy evenings and norte fronts
- Snorkel gear if you have it—December water is clear and calm
- A packable rain layer for the rare norte grey day
- Sandals and water shoes for cenotes and rocky beach entries
Know before you go
- Book Christmas and New Year's in August or September—six months minimum for any chance at good rates and resort choice
- Travel December 1–17 if you want the weather without the crowds and can save 40–60% on hotels
- Compare prices across booking platforms during the shoulder window; early December has genuine deals if you shop around
- Isla Mujeres Playa Norte is at its best this month—clear water, no sargassum, and you can golf-cart the island in breezy comfort
- Avoid arriving December 18 onward unless you've locked in lodging; walk-up availability disappears and prices spike overnight
- Reserve any Christmas-week tours, dinner cruises, or catamaran trips when you book your hotel—they sell out early
- If a norte front rolls through, it's a good day for cenote tours or Chichén Itzá—the ruins and jungle are better than a grey beach
