Yes, Costa Rica is good in December if you aim late: the Pacific dries out, but holidays bring peak crowds.

For anyone asking whether December is a good time to go to Costa Rica, the answer is yes with one big split: early December can still feel like green season, while late December is peak dry-season travel. The smartest plan is to choose the Pacific side for sun, build in flexibility for mountain areas, and book holiday-week rooms before the last-minute rush.
December is not one single weather pattern in Costa Rica. The first half is a transition month in many places; the second half is when beach towns, volcano towns, and national parks fill with winter travelers.
Going To Costa Rica In December: The Weather Shift By Coast
Going to Costa Rica in December works well after the rain breaks on the Pacific side, but early December can still feel damp in some regions. Costa Rica’s two coasts behave differently, so the right itinerary matters more than the calendar box.
The Pacific coast is the safer bet for a December vacation. Guanacaste, the Nicoya Peninsula, Manuel Antonio, and the Central Pacific tend to move into clearer, drier days as the month goes on. Trails dry out, sunset plans get easier, and boat days are less likely to be washed out.
The Caribbean coast is the main caution. Costa Rica’s Caribbean side does not follow the same dry-season rhythm, and December can be one of its wetter periods. Puerto Viejo and Tortuguero can still be rewarding, but December is not the month to choose them if your top priority is beach weather.
How Wet Is Costa Rica In December?
Costa Rica is driest in December on the North Pacific coast and parts of the Central Valley, while the Caribbean side can be wet. Mountain areas such as Monteverde and La Fortuna can still see mist, cloud, or afternoon rain, especially early in the month.
The official Costa Rica Tourism Board describes the country as having a dry season from mid-December to late April and a green season from May through mid-December, with strong regional microclimates on the Costa Rica Tourism Board climate page.
That means December is a bridge month. A trip starting December 3 should be planned with rain gear and backup plans. A trip starting December 20 can be treated much more like high season, especially on the Pacific side.
December Weather, Crowds, And Prices Compared
December in Costa Rica starts flexible and ends expensive, so the timing inside the month matters as much as the month itself. Use the first half for value and the second half for the driest Pacific odds.
| Timing | Weather Pattern | Crowds And Prices |
|---|---|---|
| Early December | Transition weather; some Pacific sun, some green-season rain | Lower than holiday weeks; better room choice |
| Mid-December | Dry season starts to settle on the Pacific side | Demand rises as school breaks approach |
| Christmas To New Year | Strong beach weather on the Pacific; mixed mountains | Peak demand for hotels, cars, and tours |
| January To February | Reliable dry-season weather on the Pacific | High season, but less compressed than holiday week |
| March To April | Hotter and drier on the Pacific; Easter can be busy | High demand around spring break and Holy Week |
| May To June | Green season starts; rain often arrives later in the day | Better value, fewer crowds, greener scenery |
| July To August | Short drier spell can occur on the Pacific side | Family travel season, with moderate demand |
| September To October | Wettest stretch on much of the Pacific; Caribbean can be better | Low-season pricing, some closures in the south |
Flights And Holiday Timing
Flights to Costa Rica are usually easier to price in early December than during the Christmas and New Year rush. Late December can still be worth it, but only if you treat flights, rental cars, and lodging as limited holiday inventory.
San José’s Juan Santamaría International Airport (SJO) works well for Central Valley, La Fortuna, Manuel Antonio, and mixed itineraries. Liberia’s Daniel Oduber Quirós International Airport (LIR) is often better for Guanacaste beaches such as Tamarindo, Papagayo, Nosara, and Sámara.
If your dates are still open, compare early December with the week after New Year before locking in the holiday window.
Where To Stay For The Smoothest December Trip
Costa Rica works best in December when you base the trip around the Pacific or a short inland loop, then treat the Caribbean as a weather-dependent add-on. A rushed coast-to-coast plan wastes the part of the month that gives you the most reliable sun.
For beaches, Guanacaste is the cleanest December choice. Tamarindo has more restaurants and nightlife; Sámara feels easier for families; Papagayo suits resort travelers; Nosara fits surf, yoga, and longer stays. Manuel Antonio is a strong pick if you want wildlife, beach time, and a compact route from San José.
For inland stops, La Fortuna works well for hot springs, waterfall trails, and Arenal Volcano views, but cloud cover is normal. Monteverde is cooler and greener, so pack layers and accept that mist is part of the deal.
Once you know which coast fits your dates, compare stays on the map before you commit to a route.
What To Do Once The Rains Ease
Costa Rica’s drier late-December weather makes beaches, volcano trails, canopy walks, and wildlife outings easier to plan. The right move is to schedule outdoor days early in the morning and leave slower meals, hot springs, or town time for later.
Good December picks include Manuel Antonio National Park for wildlife and beach time, Rincón de la Vieja National Park for dry-forest hiking, La Fortuna for hot springs and waterfall stops, and Guanacaste beaches for surf lessons or boat days. Holiday weeks need early reservations for small-group activities, because the most convenient departure times go first.
For December activities, compare tours after you choose your base, not before. A Guanacaste itinerary and a Manuel Antonio itinerary need different day trips.
Who Should Go In December?
December suits travelers who can book early, tolerate holiday crowds, and put the Pacific side first. December is less ideal for bargain hunters, last-minute planners, or anyone set on the Caribbean coast as the main beach base.
Pick December if you want:
- Pacific beach weather with a lower rain risk after midmonth.
- A holiday trip with warm mornings, outdoor meals, and family-friendly activities.
- A mix of coast, volcano country, and wildlife without the heaviest green-season rain.
Skip December, or shift your dates, if you want:
- The lowest hotel rates of the year.
- Quiet national parks during Christmas and New Year.
- The Caribbean coast as your main sun-and-beach plan.
December verdict: go in late December for Pacific sunshine, go in early December for better value, and choose January if you want similar weather without the holiday squeeze.
