The best time to visit Puerto Viejo de Talamanca is usually September and October, when Costa Rica’s southern Caribbean coast is at its driest, just as the Pacific side is at its wettest. February and March are the next-best bet. Official 2005–2025 records from Costa Rica’s national weather service (IMN) at Limón airport show September averaging 148.6 mm of rain over 15 rain days, against 481.6 mm in July.
That said, “best” depends on what you’re coming for. Surfers, turtle watchers and culture lovers each have their own months.
When is the best time to visit Puerto Viejo?
For most travelers, September and October. Here is the short version by interest:
- Driest weather and calm snorkeling: September and October.
- Bigger surf: December to March, when larger northeast swells arrive.
- Leatherback turtles: February or March to July, peaking in April and May, with certified guides only.
- Raptor migration: September to November, peaking in mid-to-late October.
- Afro-Caribbean culture: August, Costa Rica’s Historic Month of Afro-descendance, and Limón Carnival in the days around 12 October.
- Calypso: 7 May, National Calypso Day.
Why are September and October drier on the Caribbean coast?
Because the trade winds weaken. According to IMN, rainfall on this coast has two peaks: one in July, driven by the Caribbean Low-Level Jet, and another from November to January, when cold fronts (empujes fríos) push south. Between them, in September and October, the rain eases to its annual minimum.
The Pacific coast runs on a different calendar, which is why this coast surprises people. A local weather guide sums it up: the most consistently dry months here, September and October, “just happen to be the wettest on the Pacific”. It adds that rain often falls at night or in short afternoon bursts.
“Driest” is relative. Even September averages 15 rain days. This is a rainforest coast with roughly 3,274 mm (129 in) of rain a year.
What is the weather like month by month?
Monthly averages at Limón International Airport, 2005–2025 (IMN). The station is about 45 km north of Puerto Viejo, so local totals will differ somewhat.

When are the waves best for surfing?
Surf guides report the biggest swells from December to March and the flattest conditions in September and October. That is Salsa Brava season: the heavy, hollow reef break in front of town, best on an east or northeast swell and best avoided at low tide, is for experts only.
Beginners have more options. The town end of Playa Negra suits first-timers, and Playa Cocles is the area’s main surf beach, best learned with a school. Conga’s two-hour Caribbean Surf Experience starts with 30 minutes on the beach covering ocean safety and the basics; see the surf lesson page.
When can you see turtles, dolphins and migrating raptors?
- Leatherback turtles nest at Gandoca beach, inside the Gandoca-Manzanillo Wildlife Refuge, from February or March to July, peaking in April and May. SINAC says green, hawksbill and loggerhead turtles also nest in the refuge, in smaller numbers; their exact months at Gandoca are not well documented. Go only with certified guides, keep your distance and use red light only.
- Migrating raptors stream over Këköldi, the Bribri–Cabécar territory in the hills behind Puerto Viejo, from September to November, with the peak in mid-to-late October. Fall counts average about 2.5 million birds of 17 species, with a record 3 million in 2010. Visits must be arranged in advance with the local association.
- Dolphin trips leave from Manzanillo, and we don’t have seasonal data we trust. Calm seas, often in September and October, make the boat ride more comfortable. Sightings are never guaranteed; see the dolphin-watching tour.
- Sloths, toucans and frogs don’t migrate, so any month works. Our wildlife page covers what to look for.

When are prices and crowds lowest?
We’d rather not guess: there is no reliable public data on visitor numbers by month for this coast. Room rates change daily with demand, so the honest advice is to compare your exact dates. If your dates are flexible, check our current offers before you settle on a week.
What should you pack for rain and humidity?
- A light rain jacket or compact umbrella, and clothes that dry quickly.
- Two pairs of footwear: sandals for town and the beach, and shoes that can get muddy on forest trails.
- Insect repellent with at least 20% DEET. The CDC lists dengue as a year-round risk and reports malaria transmission in Limón province; see a travel-health provider before your trip.
- Sunscreen of SPF 15 or higher, and shade between 10 am and 4 pm (CDC). In national parks, SINAC asks for biodegradable sunscreen and repellent.
- A dry bag for phones and cameras on boat trips.
- Nothing extra for chargers if you’re from North America: Costa Rica uses 120 V, 60 Hz, with US-style type A and B plugs.
- Some cash, since not every small business takes cards.
