The Caribbean coast has no true dry season, but two relatively dry spells fall in February–March and September–October, which is when the Pacific side is wettest. The strongest rain runs from November to January, with December the rainiest month, and a second rainy period lasts from May to August. Leatherback turtles nest at nearby Gandoca-Manzanillo from April to August.
Best time to visit Puerto Viejo: the short answer
The best times to visit Puerto Viejo de Talamanca are the two relatively dry spells, February to March and September to October. The Caribbean coast has no true dry season, so no month is a promise, but those windows give you the best odds of long dry stretches. December is the rainiest month, and a second rainy period lasts from May to August. The Puerto Viejo de Talamanca travel guide covers the area itself, and the Costa Rica guide shows how the Caribbean fits with the rest of the country.
The reason this coast surprises travelers is that its weather runs against the Pacific side. When the Pacific is in its dry season, the Caribbean is also in a relatively dry spell, but when the Pacific is at its wettest in September and October, the Caribbean has a second dry spell. That makes Puerto Viejo a useful addition to a trip that otherwise has to avoid the Pacific rains.
Pick your window by what you want. For beach days, snorkeling and surfing, aim for February, March, September or October. For turtles, choose April to August at the nearby refuge. For a cheaper, quieter and wetter trip, the rainy periods work if you accept the weather.
How the Caribbean rain pattern works
The Costa Rica Tourism Board (ICT) describes a Caribbean climate without a well-defined dry season, with rains staying steady between 100 and 200 mm in the driest months, which is a considerable amount. Two relatively dry periods exist in the coastal zones. The first is February to March, in step with the Pacific dry season. The second is September to October, during the rainiest months on the west coast.
Between those dry spells, ICT describes two rainy periods. The first runs from November to January and is the strongest. The second runs from May to August and peaks in July, coinciding with the little summer, or veranillo, on the Pacific. The rainiest month is December, influenced by cold fronts from the Northern Hemisphere that are present between November and May, with their greatest effect from November to March. ICT adds that rain falls mostly during the night and morning.
Costa Rica's national meteorological institute (IMN) gives a physical reason for the second dry spell: when the trade winds weaken in September and October, Caribbean rainfall reaches its relative minimum. IMN also divides the coast into a northern and a southern part, with the north wetter, around 3,500 to more than 4,500 mm a year, and the south drier, between about 2,500 and 3,000 mm. Puerto Viejo lies in the southern part, which is why it is a better bet for dry spells than the Tortuguero lowlands in the north.
Month by month
January
January sits inside the strongest rainy period, which runs from November to January. Expect showers and humid days, and plan beach time around them. Ask a surf school about the day's conditions before you go in.
February and March
February and March form the first relatively dry spell and match the Pacific dry season, so this is when many visitors choose to come. Book early, since rooms near the beach fill. Showers still occur, but dry runs are longer, and the coast road, beaches and refuge are easiest to enjoy.
April
April is a transition month. Rain returns gradually, and the leatherback turtle season at the Gandoca-Manzanillo refuge begins, which ICT dates from April to August. It is a good month for wildlife if you accept some showers.
May to August
May to August is the second rainy period, peaking in July. Expect frequent rain, particularly at night and in the morning, with clear spells in between. Turtle nesting continues, the forest is at its greenest and prices are often lower. Rivers rise, so check rafting conditions and road access before you commit to a tour.
September and October
September and October are the second relatively dry spell. IMN notes that rainfall reaches a relative minimum in these months, and that the high temperatures of September coincide with that minimum. This is a good time for beach days, snorkeling and the refuge, and it is also when the Pacific coast is at its wettest, so a Caribbean add-on can rescue a trip.
November and December
November leads into the strongest rains, so expect wet mornings. December is the rainiest month, according to ICT, and it overlaps with holiday travel, so weigh the weather against the festive mood.

The table reflects ICT's description of the Caribbean pattern, not a forecast. Rain can arrive in any month, so keep a rain plan for each day. The 3-day Puerto Viejo plan shows how to arrange the days so that wet mornings do not wreck the trip.
Pacific or Caribbean: which coast in which month
The simplest way to use this pattern is to match the coast to the month. ICT puts the Pacific dry season from December to March, April as a transition month, the rains from May to October and the wettest months in September and October. In December, January and March, the Pacific is at its best and the Caribbean is wet or just drying out, so a beach holiday is easier on the west. In September and October, the Pacific is wettest and the Caribbean is in a relatively dry spell, so the east is the better beach choice.
That is why the country-level best time to visit Costa Rica page matters for a two-coast trip. If you visit in February or March, you can combine both coasts and be in a relatively dry spell on each. If you visit in September or October, favor the Caribbean for beach days and the highlands or the volcano country for the rest. In December, accept that the Caribbean is wet, or pick the Pacific.
Wildlife and activities by season
ICT's Caribbean activity lists divide the year into a dry season, December to April, and a green season, May to November. For the dry season it lists beach time and aquatic sports at Puerto Viejo, Playa Cocles and Punta Uva, wildlife tours at Cahuita National Park and the Gandoca-Manzanillo refuge, and sport fishing. For the green season it lists turtle watching at Tortuguero National Park, white-water rafting on the Pacuare River, hiking in Cahuita and the refuge, and visits to chocolate farms.
Those lists use the Pacific-style seasons, so treat them as guides, not rules. On the Caribbean coast, wildlife walks work in the drier spells and in the rain, if you are prepared. Turtles are the real seasonal event: ICT dates leatherback spawning at the Gandoca-Manzanillo refuge from April to August, and SINAC dates green turtle nesting at Tortuguero National Park from June to October, so the two seasons overlap in the middle of the year. For the northern end, read Tortuguero Village, which is reached by boat or plane, and Puerto Limón for the hinge between the two coasts.
Snorkeling and surfing depend on the swell and the runoff more than on the calendar. After heavy rain, rivers carry sediment to the sea and visibility drops, so ask a local before you book a boat. If you plan a rafting trip on the Pacuare, ask the operator about the river level, and note that tours are exposed to weather.
Hurricanes, floods and road closures
UK government travel advice says the hurricane season usually runs from June to November, as in the Caribbean, and that the June to November period is also the peak rainy season, with flooding and landslides that may close roads and create driving hazards. It advises monitoring National Hurricane Center forecasts and following local authorities. Check the forecast for your dates before you travel.
For a trip in those months, book flexible rates, leave slack before international flights and ask your lodging about the access road. The best time to visit Costa Rica page and the travel insurance guide help you decide how much flexibility to build in.
What to pack and how to plan around rain
Wet weather on this coast is a planning problem, not a reason to stay away. Pack a light rain jacket, quick-dry clothes, sandals that grip, and a dry bag for your phone, passport copy and cards. Leave cotton jeans at home, since they stay damp in the humidity. Keep your plans modular, with one outdoor block in the morning and one flexible block in the afternoon, and book tours that allow rescheduling or a refund in bad weather.
Mosquitoes also matter. UK government travel advice lists dengue, Zika and malaria among the health risks to read about before you go, and points to TravelHealthPro for current guidance. Carry insect repellent, wear long sleeves in the evening and check which vaccinations and precautions apply to your route. Medical care in Costa Rica is generally of a high standard, though ambulance services in remote areas vary, so make sure your insurance covers treatment and evacuation.
Who should pick which window
Beach travelers and first-time visitors should aim for February, March, September or October, and book early for February and March. Wildlife travelers should add April to August for turtles, accepting more rain. Budget travelers and quiet seekers can consider the rainy periods, with a waterproof bag, flexible plans and a lodging with a covered terrace. Families with small children and travelers who dislike humidity should choose a dry spell and avoid December.
Wherever you go, pack light, quick-dry clothes and a rain jacket, protect your phone and passport copy, and use an eSIM for Costa Rica so maps and coach times work offline. For where to sleep, read where to stay in Puerto Viejo, and for coach and rental options see transport in Costa Rica.
