When to Visit Costa Rica: A Travel Agent’s Seasonal Guide
When to Visit Costa Rica:
A Travel Agent’s Seasonal Guide
Two coastlines, two rainy seasons, and a wildlife calendar that never sleeps. Not every month suits every client — and the difference matters.
One of the most common questions we receive from partner agencies is “when is the best time to go?” The answer depends entirely on what the client wants to see and do. Costa Rica has micro-climates, two coastlines that behave very differently from each other, and wildlife events tied to specific months. Get this right and you set the trip up well. Miss it and you get complaints that have nothing to do with the hotels or the service.
The Two Seasons
Dry Season — December to April
The Pacific coast is dry, roads are at their most passable, and wildlife is easier to spot because the vegetation thins out. This is peak season. Lodges in Tortuguero, Arenal and Manuel Antonio fill fast — we recommend 6 months advance booking for January through March, less for April.
Best for: first-time visitors, beach clients, families, Guanacaste, Manuel Antonio.
Green Season — May to November
Rain arrives in the afternoons — typically a 3–4 hour window, then it clears. Mornings are usually dry. The country is intensely green, waterfalls are running full, and prices drop 15–30% against high season. We see some of our strongest client satisfaction scores come from green season trips: fewer tourists, more wildlife activity, and landscapes that dry season simply cannot match.
Best for: nature photographers, couples without school-age children, turtle watching, birdwatching, clients on a tighter budget.
★︎ Peak Season — Dec 20 to Jan 5, and Semana Santa
Costa Rica fills up completely during Christmas week and Easter. We regularly receive December 24–31 enquiries in January of the same year and have to turn people away. Nine to twelve months ahead is not an exaggeration for these dates. Supplements apply at almost every property, and availability at top lodges is gone first.
The Caribbean Coast: A Different Calendar
This is the detail that causes the most confusion in bookings. The Caribbean coast — Puerto Viejo, Tortuguero, Cahuita — has the opposite rainy season to the Pacific. When Guanacaste and Manuel Antonio are dry and sunny (December to April), the Caribbean can be wet and rough. When the Pacific enters green season, parts of the Caribbean dry out.
The Caribbean’s most reliable months are February to April and September to October. If a client is going specifically to Puerto Viejo for the beaches and you send them in December, they will be disappointed — we see this mistake regularly from agencies that treat Costa Rica as a single climate zone.
Tortuguero is a separate case. It sits on the Caribbean coast but the draw is canals and rainforest, not beaches — and the main event is sea turtle nesting, which runs July to October and peaks hard in August and September.
Wildlife by Month
There is no dead period for nature in Costa Rica. This calendar is one of the strongest arguments for selling the country year-round.
| Months | Wildlife Highlight | Best Region |
|---|---|---|
| Jul – Oct | Green sea turtle nesting (peak Aug–Sep) | Tortuguero |
| Oct – Mar | Leatherback turtle nesting | Tortuguero, Parismina |
| Jul – Nov | Humpback whale watching (peak Aug–Oct) | Osa Peninsula, Uvita |
| Feb – Apr | Resplendent Quetzal nesting | San Gerardo de Dota, Monteverde |
| May – Nov | Olive Ridley turtle mass arrivals (arribadas) | Ostional, Nosara |
| Year-round | Scarlet macaws, sloths, howler monkeys, toucans | Manuel Antonio, Osa, Sarapiquí |
Booking Lead Times
- Christmas / New Year and Semana Santa: 9–12 months ahead. Non-negotiable for quality lodges.
- Dry season (January–April): 4–6 months. Tortuguero and Osa need more lead time than the Pacific circuit.
- Green season (May–November): 6–8 weeks works for most itineraries. Corcovado park permits still need advance booking regardless of season.
- Turtle watching (August peak): The specific lodge nights at Tortuguero sell out months ahead — contact us as soon as a client has confirmed their travel window.
On Selling Green Season
We actively push agents to sell May through November rather than steering clients away from it. A client who visits Arenal in September after heavy rains will see waterfalls on the volcano that simply don’t exist in March. The Río Celeste in Tenorio runs its most vivid blue after rainfall. Wildlife is more active. Trails are quieter. If the client has flexibility on dates, green season is not a fallback option — it is a legitimate first choice for the right traveller.
