Costa Rica Weather in August

August falls within the rainy season in Costa Rica, known as the “green season.” It’s actually, technically, it’s their winter season. Don’t let the phrase “rainy season” put you off, it’s not all raincoats and wellies 24/7. It’s true that it rains more frequently, but generally in the afternoon.

You can expect the beaches and lowlands to have highs around 84 to 90 °F (29-32 °C) with cooler overnight averages in the  69 to 77 °F (21-25 °C) range.  Central Valley temperatures are usually 75 to 85 °F (24-29 °C) in August and it cools off more at night.

Average Rainfall and Dry Periods

This leaves plenty of time for outdoor activities in the mornings, which are hot and sunny, and in the cooler evenings. Embrace the lush and vibrant landscapes created by the rain, as the country is at its peak beauty during this time.

National Parks to Explore

Tortuguero National Park

Nestled along the Caribbean coast, Tortuguero National Park is a must-visit destination in August. It’s renowned for its rich biodiversity, including the famous turtle nesting season (mid-July to the beginning of September is nesting season).

Witness the awe-inspiring sight of endangered sea turtles (the world’s largest population of Green Turtles) making their way to the shore to lay their eggs. There will be approximately 100,000 nests along the shore at this time of year.

Explore the park’s 300 square miles of jungle, beaches, and mangroves. There’s an extensive network of canals by boat, spotting a wide variety of wildlife along the way. And three major hiking trails that range from 2-4 miles long.

What is the weather like in Tortuguero National Park in August?

The temperature is around 30°c and at night it feels like 24°c. In August, Tortuguero receives 376.48 mm of rain and approximately 12 rainy days in the month (according to the Park’s website.)

Monteverde Cloud Forest Biological Preserve 

People head to Torteguero for the turtles, but they head to Monteverde for the birds!

For avid birdwatchers, a visit to the Monteverde Cloud Forest Biological Preserve is a must during your August adventure in Costa Rica. This pristine and enchanting cloud forest is alive with biodiversity and offers a unique opportunity to witness the lush ecosystem of the region.

Here you can explore the well-maintained trails that wind through the misty forest, where you can spot rare bird species, including the Resplendent Quetzal. The Resplendent Quetzal is the national bird of Costa Rica, but it’s just one of the many beautiful birds that you can find here.

Immerse yourself in the ethereal beauty of the cloud forest and marvel at the abundance of plant and animal life that call this preserve their home.

Corcovado National Park

Located on the Osa Peninsula, Corcovado National Park is a paradise for nature enthusiasts. August offers an excellent opportunity to explore its dense rainforests and encounter an array of exotic wildlife, including jaguars, tapirs, and monkeys. Take a hike through the park’s well-maintained trails, guided by knowledgeable experts, to fully appreciate its natural wonders.

Trails this time of year can be slippery, and good ankle support and excellent traction are essential if you’re heading to any of these parks for a hike. Want to know more about hiking here, check out my hiking in Costa Rica post. It has tips like, don’t wear open-toed shoes while trekking through the jungle trails.

And I will share with you that when I go to Casa Vitality in Nosara Costa Rica in August (and every other time of year) I only wear the Ladies Merrell Mid Waterproof MOAB lll Hiking Shoe.

Costa Rica Tours and Itineraries

tickets and itineraries for a trip to costa rica in august

Embarking on guided Costa Rica tours is an ideal way to make the most of your August adventure. Tour operators offer specialized itineraries that cater to various interests and preferences, ensuring you have a memorable trip.

You don’t have to use a tour operator if you don’t want to. The country is safe and easy to get around in. Although the ability to speak Spanish, or access to a sold translation app for your phone, would be helpful. But that doesn’t mean you shouldn’t book ahead if you want transportation from the airport to the city or town of your destination.

When you arrive at the national airport in either Liberia or San Jose, you have several options.

  • Your hotel may have private shuttle transportation to take you to your destination.
  • You can rent a car. An SUV is best, especially in the rainy season, and make sure you have a navigation app of some sort or a map. In Costa Rica, there are virtually no road signs in this country. You might want to check out my post on driving in Costa Rica.
  • There are plenty of buses in the larger cities. Public transportation is quite reliable.
  • The regional airport takes passengers from the two major airports to smaller more distant locations. Sansa Airlines, which is how I get to Nosara, has flights to 11 domestic destinations.
  • Ground transportation shuttle services can be used in lieu of flying. Costa Rica Shuttle is one of the largest companies in the country. If you don’t want to take a “milk run” as they say, ask for private service. Try Costa Rica Shuttle, they’re one of the largest services in the country.

Travel Tips and Advice

Pack for the Rain

Given the rainy season, it’s essential to pack appropriate rain gear, including waterproof jackets, hiking boots, and quick-drying clothing. Don’t forget to bring a sturdy umbrella and a waterproof cover for your backpack or at least a waterproof bag.

With all my trips to Costa Rica, this is what I keep in mind.

  • It’s a warm rain, not those icy drizzles you might be used to, make sure any apparel is lightweight. Once it stops raining, it will be hot and humid until things dry up. That makes extra clothing hot and sticky, for too long.
  • If you choose a raincoat for staying dry, make sure it has a hood. And preferably a hood with a peak on it. Choose one like the waterproof jacket from BALEAF, it’s lightweight, with a peaked hood and designed for activities like hiking, running, or cycling. And it packs up very small.
  • Umbrellas must be wide and sturdy. It’s not so much the wind that umbrellas need to withstand, but the pounding from torrential rain.
  • A wide-brim waterproof hat. I have one with a neck flap. It keeps the rain from rolling down the back of my shirt and protects my neck when I go fishing.
  • Sturdy waterproof hiking shoes for good traction on the trails. As mentioned above, I prefer Merrell MOAB lll.
  • A waterproof backpack.
  • A waterproof dry bag (they’re also sand proof, so they’re handy at the beach). They are super handy if you go out fishing on a charter or out kayaking. Take a look at this one from Earth-Pak.

Plan for Rainy Days

Be prepared for occasional rainy days by having a mix of indoor and outdoor activities in your itinerary. Visit museums, enjoy a Costa Rican cooking class, or relax in hot springs near Arenal Volcano during a downpour.

Explore the Pacific and Caribbean Coasts

Take advantage of Costa Rica’s diverse coastlines. Head to the Caribbean coast for stunning beaches and water sports, or explore the Pacific coast for excellent surfing and breathtaking sunsets.

The surfing is still great in August. And there are actually fewer tourists on the great Pacific surfing beaches like Montezuma, Cabuya, Guiones, Pelada, or Santa Teresa.

And trust me, you’re never too old to learn to surf! Even those of us over 60 can learn to ride a wave.

Spend Time in San Jose and Central Valley

Consider starting or ending your trip in the capital city, San Jose. Explore the city’s museums, historic sites, and vibrant markets. Additionally, don’t miss the opportunity to visit the Central Valley, known for its picturesque landscapes and coffee plantations.

Two cultural events happen in Costa Rica in August, and if you’re in San Jose, you should check them out.

  • Virgin of Los Angeles Day: Costa Rica’s largest religious holiday – pilgrims march on foot or on their knees toward Cartago’s Los Angeles Basilica to pay honour to La Negrita and ask for a wish to be granted for them, Costa Rica’s black Virgin. August 2.
  • San Ramon Day Parades: Dancing and music help celebrate the arrival of 30 patron saints from nearby towns to honour San Ramon’s own patron saint in San Ramon, Alajuela. August 30.
  • Mother’s Day is August 15th in Costa Rica…so I like to go and double up on cards and chocolate!

August in Costa Rica: The Low Season Advantage

Travelling to Costa Rica in August has its advantages. During the low season, you can benefit from lower prices on airfare, accommodations and tours. The crowds are generally much smaller so you can experience nature on a more “up close and personal level.

This is especially true when it comes to having a greater chance to spot wildlife in national parks. The rainforest is incredibly lush this time of year, and it makes for great photos! Even your cell phone camera will capture amazing flowers and birds.
