Costa Rica weather in April is hot, sunny, and beautifully dry across most of the country it’s the last full month of the dry season, which makes it one of the most reliable months of the year for sunshine, long beach days, and easy wildlife spotting with kids. We’re a family that lives here and has spent more than 20 years helping other families travel Costa Rica well, and April is a month we genuinely love.

But we’ll be honest with you, the way we’d be honest with a friend: April comes with two things you’ll want to plan around real heat on the Pacific coast and the Semana Santa (Holy Week) crowds. Neither is a dealbreaker. Both are easy to handle once you know they’re coming.

This guide walks you through exactly what April weather in Costa Rica looks like by region, what to pack, what to do with the kids, and the one local moment that surprises almost every first-time family.

April is one of the best months to visit Costa Rica with kids if your family wants dependable sunshine and easy outdoor days. As the closing month of the dry season, it gives you the warm, mostly rain-free weather that makes beaches, hikes, and wildlife tours simple to plan around little ones and grandparents alike.

The trade-off is that April is still firmly high season, so you’ll share the trails and beaches with other travelers, and prices stay near their yearly peak. For most families, the reliability is worth it there’s real comfort in knowing your sloth hike or zip-line morning probably won’t get rained out.

April also happens to be one of the easier months for spotting animals. With water sources shrinking after months of dry weather, sloths, monkeys, and birds gather where the water still flows, so wildlife tends to come to you. If your kids have a “please can we see a sloth” list, this month rarely disappoints.

One honest caveat we always share: this is still a tropical country, and “dry season” doesn’t mean “no rain ever.” A short afternoon shower can roll through, especially in inland and higher areas. We see it as a built-in excuse for an ice cream break.

If you’re weighing months, our Costa Rica weather guide by month gives you the full year at a glance so you can compare April against the rest.

Weather in Costa Rica in April is warm to hot and predominantly dry, but it varies a lot by region because of the country’s mountains and two coastlines. Expect strong sun and high temperatures on the Pacific, milder days in the Central Valley, and a different rhythm altogether on the Caribbean side. Here’s how April feels in the places families visit most.

Pacific Coast & Guanacaste (hot, dry, peak sun)

The North Pacific Guanacaste and the Nicoya Peninsula is the hottest, driest part of the country in April, with intense midday sun and very little rain. Daytime highs commonly sit in the low-to-mid 90s°F (around 32–35°C) and the landscape turns golden and dry.

This is classic beach-and-pool territory. We tell families to treat the heat with respect here: hats, reef-safe sunscreen, lots of water, and a slower pace from roughly 11 a.m. to 3 p.m. Mornings and late afternoons are magic; midday is for shade.

Arenal & La Fortuna (warm, mostly dry, lush)

Around Arenal Volcano and La Fortuna, April is warm and mostly dry, but greener and a touch more humid than Guanacaste thanks to the rainforest setting. You may catch a brief afternoon shower, which only makes the hot springs feel better at the end of the day.

This region is a family favorite for a reason volcano views, gentle hikes, and thermal pools the whole group can enjoy. For a deeper month-by-month look at this area specifically, see our La Fortuna weather guide for families.

Caribbean Coast (its own rhythm)

The southern Caribbean, around Puerto Viejo and Cahuita, marches to its own beat and doesn’t follow the Pacific’s dry-season pattern as strictly. April is often warm and pleasant here, but this coast can see showers in any month, so pack a light rain layer just in case.

The upside is fewer crowds than the Pacific hotspots and a completely different, laid-back vibe think Afro-Caribbean culture, calm swimming spots, and easygoing beach days.

Central Valley & San José (mild and comfortable)

The Central Valley, including San José where most families fly in, is the mildest region in April, with warm days and noticeably cooler evenings thanks to the elevation. It’s a comfortable landing spot and a gentle place to recover from jet lag before heading to the coast.

You might see a short late-afternoon shower as the month goes on, but mornings are typically bright and easy for exploring.

Semana Santa Holy Week is the single most important thing to plan around in April, because it’s the biggest holiday week of the year in Costa Rica and it changes how the whole country moves. The dates shift each year; in 2026 Easter falls in early April, so Holy Week lands at the very start of the month

During this week, many Costa Rican families take their own vacations, so beaches, hotels, and roads fill up with locals as well as international visitors. It’s a wonderful, festive time to experience the culture but it’s also when you most need to have your accommodations and tours booked well in advance.

A few honest, practical heads-ups we give every family traveling this week:

• Book early. Family rooms, connecting rooms, and popular tours sell out first around Easter. This isn’t the week to wing it.
• Roads get busy. Travel between regions can take longer than usual, especially on the Thursday and Friday of Holy Week. Build in buffer time and don’t over-schedule.
• Some businesses close or shorten hours, and certain areas still observe the traditional custom of not selling alcohol on Holy Thursday and Good Friday 
• Beaches are joyful but packed. If your family prefers quiet, consider a quieter region or build beach time earlier or later in the month.

None of this should scare you off Semana Santa can be one of the most memorable times to see Costa Rica’s culture up close. It just rewards families who plan ahead, which is exactly what we’re here to help with.

For April, pack for heat and sun first: lightweight, breathable clothing, swimwear for every family member, and serious sun protection are the non-negotiables. Because this is one of the driest, brightest months, the right packing list is less about rain gear and more about keeping everyone cool, covered, and hydrated.

Here’s the family-tested short list we share:

• Sun protection: wide-brim hats, reef-safe sunscreen, sunglasses, and rash guards for the kids (much easier than reapplying sunscreen every hour).
• Hydration: refillable water bottles for everyone the heat sneaks up on little ones.
• Footwear: sandals plus closed walking shoes for trails and hanging bridges.
• Bug protection: insect repellent, especially near rainforest and water.
• A light rain layer: a packable poncho or jacket, just in case of a quick shower inland or on the Caribbean.
• Swim gear: with thermal pools and beaches, swimsuits get used daily a dry backup pair saves the day.

Our number-one tip for traveling with kids in the heat: plan adventures for the morning, build in pool or shade time in the afternoon, and you’ll have a happier, less melty crew.

April’s dry, sunny weather makes it one of the best months for outdoor family adventures, from beach days to wildlife spotting to gentle rainforest hikes. With reliable sunshine and animals gathering near shrinking water sources, the classic Costa Rica experiences are at their easiest and most rewarding this month.

A few that work beautifully for mixed ages and multigenerational groups:

• Wildlife walks in places like Manuel Antonio, where sloths, monkeys, and birds are often visible on short, shaded trails gentle enough for grandparents and exciting for kids.
• Safe, age-appropriate adventures like calm-water rafting, hanging bridges, and zip-lines with operators who tailor activities to children’s ages.
• Beach and pool days along the Pacific, ideal for sandcastles, boogie boarding, and that all-important downtime.
• Hot springs near Arenal, a relaxing reward after a morning hike that everyone from toddlers to grandparents enjoys.

We design every itinerary around real family rhythms naps, snack breaks, and different energy levels so no one feels rushed. You can browse our family-friendly tours to see how we match adventures to your kids’ ages.

In April, the most important accommodation tip is simple: book early, especially around Semana Santa. Because this is peak dry season and the biggest local holiday week falls in early April 2026, the best family hotels and connecting rooms fill up months ahead — so the families who plan first get the most choice.

Where you stay shapes your whole trip, and the right region depends on what your family wants:

• Guanacaste / North Pacific: sunny beaches and family all-inclusive resorts — easy, warm, and great for younger kids who want pool-and-beach simplicity.
• Manuel Antonio: rainforest meets swimmable beaches and excellent wildlife, perfect for first-time family travelers who want a bit of everything.
• Arenal / La Fortuna: volcano views, hot springs, and gentle adventure for multigenerational groups.

Many families combine two regions for example a few nights in Arenal followed by beach time on the Pacific for a trip that balances adventure and rest. Our guide on where to stay in Costa Rica for families breaks down the best fit by your kids’ ages and travel style.

If you can travel either month, the choice between April and May comes down to a trade-off: April gives you the most reliable sunshine at peak prices, while May begins the green season with fewer crowds, lower rates, and a lush, refreshed landscape. There’s no single “right” answer only the right fit for your family.

Choose April if your priority is dependable dry weather, beach reliability, and you don’t mind high-season crowds and pricing. It’s the safer bet for a sun-focused trip.

Choose May if you’d rather have a quieter, greener Costa Rica and better value, and your family is comfortable with the occasional afternoon shower. The early green season still has plenty of sunshine, and the countryside comes alive after the first rains.

Costa Rica weather in April is about as dependable and sunny as it gets the reward is long beach days and easy wildlife mornings; the homework is handling the heat and booking ahead of the Easter rush. That’s exactly the kind of planning we love to take off your plate.
