December is one of the best months to visit Puerto Vallarta, especially for travelers who want warm weather, festive energy, and the start of whale watching season. The humidity of the summer has dropped significantly, making the afternoons feel tropical but comfortable. The trade-off is higher prices and very heavy crowds from Christmas through New Year. I have visited many times during this window, and while the atmosphere is electric, you must plan for the logistics of a city operating at 100% capacity.
December Quick Facts
- Weather: Warm afternoons, refreshingly cool evenings.
- Crowds: Moderate early in the month; extremely heavy after December 20.
- Prices: Standard peak season rates; highest prices and minimum stays for the holidays.
- Ocean: Swimmable and clear, though cooler than the “bathtub” temps of summer.
- Highlights: Humpback whales, Lady of Guadalupe processions, and festive dining.
The Verdict: If you enjoy cultural festivals and don’t mind sharing the sidewalk, early to mid-December is fantastic. If you are looking for a quiet, secluded beach escape, the last ten days of the month will likely feel overwhelming and overpriced. Flexibility and early bookings are essential for a successful December trip.
Who December is Best For
- Best for: First time visitors, whale watchers, culture seekers, and travelers who enjoy walking and outdoor dining without intense humidity.
- Less ideal for: Strict budget travelers, people who are sensitive to noise, or anyone looking for a quiet, low-key Christmas.
Puerto Vallarta Weather in December
By December, the rainy season is largely over. While an occasional tropical shower can happen, the weather is usually much drier and sunnier than in summer and early fall. Expect daily highs around 82°F (28°C). The most significant change is the drop in humidity, though warm afternoons still feel tropical.
The Evening Cool Down: Unlike the Caribbean, Puerto Vallarta evenings often feel pleasantly cooler than the afternoon. As the sun sets behind the bay, a breeze frequently rolls off the Sierra Madre mountains. Temperatures can dip into the low 60s (17°C) at night. I always tell travelers to bring a light layer for waterfront dinners.
Water Temperatures: The Pacific is swimmable in December, with water temperatures hovering around 77°F to 79°F. It feels refreshing rather than hot. Visibility for snorkeling is generally high unless there has been a recent swell.
December by the Week: When to Go
- December 1 to 12 (Festival Period): This is the time for the Festival of Our Lady of Guadalupe. It is culturally rich but logistically challenging. Expect daily processions, road closures in Centro, and a lot of noise. It is a beautiful time to be in the city if you prioritize culture over quiet.
- December 13 to 20 (The Sweet Spot): This is often the best stretch for travelers who want good weather and whale tours without the peak Christmas crowds. Prices are high but have not yet reached their holiday “spike,” and the city feels more manageable.
- Christmas and New Year: This is the busiest time of the year. The city is packed, traffic in the Romantic Zone is slow, and everything requires a reservation. Many villas and high end hotels require 7 night minimum stays during this period.
December vs. Other Months
- December vs. November: November is still a “transition” month. You might get a late tropical rain, and the humidity can still linger. By December, the rain has stopped completely, and the humpback whales have officially arrived in the bay.
- December vs. January: January is slightly cooler, both in the air and the water. While December is festive and green, January can feel a bit more “browned out” as the dry season takes hold. January is also more popular with the “snowbird” crowd, while December is driven by holiday travelers.
Whale Watching in Puerto Vallarta in December
Whale watching season typically opens around December 8. This is when Humpback whales arrive in Banderas Bay to mate and give birth. While you can see whales in December, keep in mind that this is the beginning of the season. January and February are often the strongest months for frequent sightings and more active surface behavior like breaching.
If you are booking a tour in December, I recommend going with a reputable operator that uses smaller boats and employs marine biologists. It makes a massive difference in the quality of the education and the respect shown to the animals.
Is December a Good Time to Visit vs. Other Months?
- December vs. November: December is more settled. November is a transition month where humidity can still be high and late season storms are possible. December also marks the official start of whale watching, which you won’t get in November.
- December vs. January: January is slightly cooler and the crowds thin out after the first week. While December is lush and green from the summer rains, the landscape begins to dry out in January. January is generally better for serious whale enthusiasts.
- December vs. February: February is the peak of the dry season and the peak for whale sightings. However, February does not have the festive, high-energy atmosphere created by the December religious festivals and holiday celebrations.
Best Areas to Stay in Puerto Vallarta in December
- Romantic Zone (Old Town): The best choice for those who want to be in the center of the dining and nightlife scene. It is the most walkable area but also the loudest, especially during the holidays.
- Centro: Ideal for travelers who want a historic feel and proximity to the Guadalupe processions. Note that street closures and loud music are frequent here during the first 12 days of the month.
- Marina Vallarta: A flatter, easier area that is very family friendly. It is conveniently located near the airport and is the primary departure point for most whale watching and sunset cruises.
- Conchas Chinas: A quieter, upscale hillside area south of town. It feels removed from the crowds, but depending on exactly where you stay and the time of day, getting into the Romantic Zone can take 15 to 20 minutes due to traffic.
- Nuevo Vallarta (Nuevo Nayarit): Best for those who want a traditional resort experience with long, flat beaches. It is a 30 to 45 minute drive from downtown Puerto Vallarta, so it is less ideal if you want to experience the local festivals daily.
Common December Mistakes
- Assuming All Pools are Warm: Some upscale resorts and condo properties heat pools in winter, but do not assume every pool will feel warm. If a heated pool is a deal breaker for you, ask the property specifically before booking.
- Ignoring the Guadalupe Traffic: During the first 12 days of December, traffic in Centro can come to a standstill. If you have a dinner reservation or a tour to catch, walking is often faster than taking a taxi or Uber.
- Packing Only Beachwear: I see people shivering at outdoor tables every December. The “Pacific breeze” is real. Bring a sweater or a light jacket for the evenings.
- Booking Holiday Dinners Late: If you want to eat at a popular spot like La Palapa or Hacienda San Angel for Christmas Eve or New Year, you should book at least a month in advance.
What to Pack for Puerto Vallarta in December
- Light Layers: A sweater, pashmina, or light jacket for evenings and boat tours.
- Sturdy Footwear: The cobblestones in the Romantic Zone and Centro are slippery and uneven. Sturdy sandals or sneakers are much better than thin flip flops.
- Binoculars: These are great for spotting whales from your balcony or the beach without having to be on a boat.
- Earplugs: If you are staying in the Centro or Romantic Zone during the festivals or Christmas week, earplugs are a must for light sleepers.
Frequently Asked Questions
Is Puerto Vallarta crowded at Christmas?
Yes, it is extremely crowded. Expect wait times at restaurants, packed beaches, and slow traffic. If you prefer a quiet experience, visit in the middle of the month instead.
Can you swim in Puerto Vallarta in December?
Yes. The water is clear and comfortable, though it is not as warm as it is in August or September. Most people find it perfect for a midday swim.
Is Puerto Vallarta humid in December?
The humidity drops noticeably compared to the summer. While it still feels tropical, you won’t experience the “drenched in sweat” feeling that comes with a July or August visit.
Should I stay in the Romantic Zone or Marina Vallarta?
Choose the Romantic Zone if you want to walk to everything and enjoy nightlife. Choose the Marina if you want a quieter, resort style stay that is closer to the airport and whale tour departures.
Do I need to book whale tours in advance?
During the holiday week (Dec 20 to Jan 2), yes. Tours will sell out. Earlier in the month, you can usually book a few days in advance.
