Mexico in December: Weather, Where to Go, and Holiday Tips

Is Mexico good to visit in December?

Yes. December sits squarely in Mexico's dry season, so most of the country is sunny and warm, hurricane season is over, humpback whale season opens on the Pacific, and the holiday calendar brings some of the best atmosphere of the year. The thing to plan around is price: rates and crowds rise from mid-December into the Christmas and New Year peak, so your dates matter as much as the month.

This guide covers what December weather actually delivers region by region, where to go for beach, culture, or wildlife, the Mexican holidays that shape the month, and how the value and peak windows work. It links down to our detailed Punta Mita in December guide for the Pacific coast.

What this guide covers

This is a seasonal guide, not a ranking. It draws on Mexico's regional dry-season patterns, the Pacific and Baja whale-season timing, the Mexican December holiday calendar, and how luxury resorts and pricing behave across the month.

Mexico weather in December, by region

December is one of the driest, most settled months almost everywhere in Mexico. The table below covers what to expect by region. Broadly, plan for warm, sunny days and cooler evenings, with the biggest differences being desert nights in Baja and cool highland nights inland.

Where to go in Mexico in December

December suits almost any region, so the choice comes down to the kind of trip you want. The luxury bases below are grouped by what each area does best in December.

Christmas, New Year's, and Mexican holidays in December

December is one of Mexico's richest months for celebration, and the calendar is worth planning around. The Feast of the Virgin of Guadalupe on December 12 draws huge pilgrimages, above all to the Basilica in Mexico City. Las Posadas run nightly from December 16 to 24, with candlelit processions reenacting the search for shelter. In Oaxaca, the Night of the Radishes (Noche de Rábanos) on December 23 turns carved radishes into an art contest. Nochebuena and Christmas fall on December 24 and 25, and New Year's Eve closes the month.

The calendar also splits the month in two. From December 1 to 18, dry-season weather is already at its best and rates sit in the pre-holiday range, which is the value window. From December 19 to January 3, Mexico moves into its winter peak: rates climb, resorts set holiday minimum-stay requirements, and restaurants book out in advance. If the holiday atmosphere is the point, reserve early and lock in Christmas Eve, Christmas Day, and New Year's Eve dining when you book. If value matters more, early December delivers the same weather for less.

Best things to do in Mexico in December

Start of whale season. Humpbacks arrive on the Pacific coast and around Los Cabos in December, so a morning boat outing is one of the signature activities of the month.

Join the festive calendar. Time a trip around the Feast of the Virgin of Guadalupe, Las Posadas, or a city's Christmas markets for the fullest sense of the season.

Make the most of dry-season beaches. With reliable sun and warm water on the Pacific and clearer water on the Caribbean, December is prime time for beach and pool days.

Head to the highlands for culture. Mexico City, San Miguel de Allende, and Oaxaca are mild, dry, and dressed for the holidays, an easy contrast to the coasts.

Who should visit Mexico in December?

Strong fit for:

• Beach and sun travelers who want reliable dry-season weather

• Whale watchers happy to catch the opening of the season

• Travelers who want the festive calendar and holiday atmosphere

• Culture-focused trips to Mexico City and the colonial highlands

Weaker fit for:

• Budget-focused travelers over Christmas and New Year

• Anyone wanting peak whale numbers, which come in January and February

• Travelers who dislike minimum-stay requirements and booked-out restaurants

Final take

December is one of the best months to travel almost anywhere in Mexico: dry and sunny from the Pacific to the Caribbean, with whale season opening and the festive calendar at its peak. The decision that shapes the trip is timing. Travel December 1 to 18 for the same weather at pre-holiday rates, or commit early to the December 19 to January 3 peak if the holiday atmosphere is what you are after. Either way, match the region to the trip you want, and book the resort, the festive dining, and any whale outing ahead of time.

Frequently asked questions

Is Mexico good to visit in December?

Where should you go in Mexico in December?

For beach and the start of whale season, the Pacific coast (Riviera Nayarit and Punta Mita) and Los Cabos. For the clearest turquoise water, the Riviera Maya, which sees little sargassum in winter. For culture and festive atmosphere, Mexico City with day trips to San Miguel de Allende and Oaxaca.

Is December a cheap time to visit Mexico?

It depends on the dates. December 1 to 18 is the value window, with strong weather and pre-holiday rates. December 19 to January 3 is the winter peak, with higher rates, minimum stays, and booked-out restaurants. For value, travel in early December.

Can you see whales in Mexico in December?

Yes. Humpback season opens in December on Banderas Bay off Riviera Nayarit and around Los Cabos. December is early season, so sightings build through the month toward the January and February peak. Gray whales gather in the Baja lagoons later in the season.
