At dawn in April, the canals of Tortuguero are glassy and green, and the first sound is a chorus of howler monkeys rolling out of the treetops before the boat engines start. The village is a strip of painted wooden houses between the lagoon and the sea, with no roads in or out. April brings warm, humid days, a mix of sun and showers, and the holiday rhythm of Semana Santa, when Costa Rican families fill the coast.
What is the weather like in Tortuguero in April?
April in Tortuguero is hot, humid and showery, with rain on many days but usually in passing bursts rather than all-day downpours.
| Month | Average high (°F) | Average low (°F) | Rain days | Sea (°F) |
|---|---|---|---|---|
| March | 81.9 | 72.4 | 11.1 | 83.0 |
| April | 83.3 | 73.9 | 11.6 | 84.4 |
| May | 83.4 | 74.4 | 24.2 | 86.2 |
Mornings are often the best part of the day, soft and bright, with mist lifting off the canals and birds active along the banks. By midday the air turns heavy and sticky, and the shade of a boat canopy or a veranda becomes the most valuable real estate in town. At night it remains warm enough to wear just a T-shirt, but a fan or air conditioning will help you sleep well.
Rain on this Caribbean coast can arrive at any hour, and it tends to come as a sudden shower that drums on tin roofs for a while and then moves on. A heavy downpour is uncommon this month, but showers can still interrupt time outdoors. The forest is lush and loud after a shower, and wildlife often becomes more active as it clears.
Dress for wet heat: light, quick-drying fabrics, a real rain jacket rather than an umbrella, and shoes that can get muddy. The light is flat and gray under cloud and golden when the sun breaks through, which suits photography of the canals and the village alike.
Can you swim in Tortuguero in April?
The warm sea may look inviting, but Tortuguero’s beaches are not suited to swimming, so stay at the water’s edge.
The Caribbean beach in front of Tortuguero is a wide, wild stretch of dark sand with surf rolling in, more a place for walking than for bathing. Rip currents are a grave danger throughout Costa Rica, drowning several American visitors annually, and most beaches have no lifeguards or warnings about hazardous conditions. Nobody will blow a whistle for you here, so the sensible habit is to stay at the water’s edge, wade rather than swim, and never go in alone.
If you want to cool off, the swimming pools at many lodges do the job without the worry. The spot will suit families with young kids and uneasy swimmers much better. Bring a swimsuit anyway, since the warm water on your ankles at the end of a beach walk is one of the pleasures of the month.
What to do in Tortuguero in April
The best thing to do in Tortuguero in April is to get on the water at first light. Boat tours through the narrow canals, often in a quiet paddle-powered or electric boat, put you under low branches where you may see caimans on the banks, herons stalking the edges, kingfishers, basilisk lizards and sometimes sloths in the cecropia trees.
Monkeys, including howlers and spider monkeys, are common sounds and sometimes sights. Early morning is when the birds and animals are most active, and the light is soft enough to be flattering.
April sits outside the main green turtle nesting months.
If you want to watch turtles nest at night, you go with a licensed guide, since the beach is no spot to explore alone after dark. If turtles are your main reason for coming, ask your lodge what is possible in this period before you plan around it.
The canals by boat or kayak
A guided boat trip through the canals and lagoons at first light lets you watch the forest wake up. You glide along the water while a guide spots the animals you would walk past on your own: a green iguana high on a branch, a tiny poison dart frog, a sleeping bat clinging to a trunk. Kayaking lets you move more quietly and slowly, and it suits people who like to feel the rhythm of the water.
A shower can come up with little warning, so a rain jacket or poncho in a dry bag is the thing to have with you. After a downpour the forest steams and the birds get loud, which is often when you see the most. Binoculars help more than a long camera lens in the dim light under the canopy.
The village and the beach walk
Tortuguero village is small enough to walk end to end in a short time. In tiny sodas, which are family-run eateries, casado is available, a dish featuring rice, beans, plantains and fish or chicken, plus coconut milk rice and beans, a Caribbean staple, as wooden houses all around display bright green and blue paint. Craft shops sell carved wood and tropical-themed souvenirs, and a few cafés serve cold fruit drinks that are very welcome in the afternoon.
Behind the village a long beach runs along the sea, and a walk there at the cooler hours of morning or late afternoon is a pleasure. You will see driftwood piled high, sea birds, and the surf, but remember the currents and stay out of the water. In the village, a center for conservation and a turtle museum shares the tale of the nesting beaches and makes a fine stop when it rains.
April is a month of holidays on the calendar. April 11 is Juan Santamaria Day, a national holiday, and Holy Week (Semana Santa) moves every year. Holy Thursday and Good Friday are national holidays, most businesses close, and Costa Rican families fill the beaches. In Tortuguero this means more domestic visitors around the holiday days and a livelier village, though some small businesses may close.
A two-day itinerary for Tortuguero in April
Day 1. Arrive by boat or small plane, since there are no roads in, and settle into your lodge. Spend the late morning in the village for a first look at the painted houses and a lunch of casado at a soda. In the afternoon, when the day is hottest, rest in the shade or by the lodge pool, and watch for birds from the veranda.
The beach walk belongs to late afternoon, once the heat lets up and the light goes gold. Daylight lasts a little over twelve hours in mid-April, so you have time for the walk and still get back before dark. Dinner is at the lodge or a village restaurant, and an early night suits the next morning’s start.
Day 2. Be on the water at first light for a guided canal trip, the best hours for wildlife and the coolest of the day. Come back for breakfast, then spend the mid-morning exploring the village, which also works well between showers. Lunch is a simple plate of rice and beans cooked in coconut milk.
In the afternoon, take a kayak out on a quieter canal or browse the craft shops, keeping a rain jacket close. If the weather turns, a long lunch and a book on a covered porch is no hardship here. Finish with a last look at the lagoon as the light fades and the frogs begin their evening noise.
Is Tortuguero busy in April?
Tortuguero is busiest in April around Holy Week and quieter outside it, since this is not the peak turtle season.
During Semana Santa, Costa Rican families travel to the coast and the village feels livelier, with lodges filling and boat tours more crowded. Outside those days, April is calmer, and you may have a canal almost to yourself in the early morning. Holy Thursday and Good Friday are national holidays when most businesses close, so some small shops and restaurants may keep short hours.
Since boats and small planes are the only way into Tortuguero, booking a lodge matters most, and the custom is to reserve early for Holy Week and later for the calmer weeks. Transfers by boat or plane are part of the planning too, so put them in place before you settle on dates.
What to pack for Tortuguero in April
Pack light and quick-drying, because the air is humid and showers come and go.
- A real rain jacket or poncho, for showers that arrive suddenly on the canals
- Quick-drying shirts and shorts, since nothing dries slowly in this humidity
- Waterproof sandals and closed shoes, for muddy paths and wet boat decks
- Binoculars, to spot birds and monkeys high in the trees
- Insect repellent and sunscreen, for the mosquitoes and the strong sun
- A dry bag, to protect your phone and camera from rain and spray
Good to know before you go
The U.S. State Department rates Costa Rica Level 2, ‘Exercise increased caution,’ due to crime; it says petty crime is common throughout Costa Rica and that violent crime also affects tourists, including armed robbery, homicide and sexual assault.
Reaching Tortuguero requires some forethought, as boats and small planes are the only way into the village and no roads lead there. The Atlantic hurricane season does not affect this month, so rely on your lodge for the latest on weather and boat schedules. Around Holy Week and Juan Santamaria Day on April 11, expect holiday closures and busier lodges, and book your transfer and your room first.
Tortuguero in April vs March and May
March is a little cooler and a touch drier, with a slightly cooler sea. It suits travelers who want the least rain in this stretch and a calmer village, though Holy Week can fall in either month, so the holiday crowds can move with it.
May is when the rain really sets in, with rain on most days and far more of it, and the sea is at its warmest. April brings the forest to its peak of green, while the canals can take on a moodier feel, though trips are more prone to interruption.
If you want the best chance of mild, mostly workable weather with a warm sea, April sits in the middle and is a good compromise. Choose March if you want to lean toward drier days, and May only if you do not mind a wetter trip in exchange for lush green scenery.
Is April a good time to visit Tortuguero?
Yes, April is a good time to visit Tortuguero for travelers who like early boat rides, birds and monkeys, and a village that is lively but not packed outside Holy Week.
It suits people who do not mind humidity and the odd shower, and who come for the canals rather than for nesting turtles. It is less suited to anyone whose heart is set on watching turtles come ashore, since the main green turtle season is later in the year, or to anyone who wants to swim in the sea.
On arrival, book your first canal trip for the next morning, since the early hours are the best for wildlife. April in Tortuguero is the sound of howler monkeys at dawn, a boat sliding under dripping branches, and a warm rain that smells of wet leaves.
