August falls right in the middle of Costa Rica's "green" season, a rainier time of year when all of the country's famous flora is in bloom. Take advantage of the precipitation with whitewater rafting, or head to the Caribbean coast if you're looking for a vacation with more sun. One of the biggest religious holidays of the year occurs during this month, too. Read on for more on the nature and festivities of Costa Rica in August.


August is the height of Costa Rica's "green" (rainy) season (May to November). During this month you can expect temperatures to be a few degrees cooler in most places, and also there will be more frequent rains. Know that if you're planning some beach time in places like Manuel Antonio National Park or other locales on the central and southern Pacific coast, there will likely be significant rainfall. That said, the northern Pacific Coast remains relatively dry even during this green season. 

Crowds & Costs

The bright side of traveling during this low season is that in most parts of the country you'll find cheaper hotel prices and fewer crowds. Typical discounts are in the 15-20% range, but it's not uncommon to score hotel rooms for even 50% off during these low-season months. Of course, international flights will be cheaper as well. Fares offered by the main local carrier, Sansa Airlines, typically do not fluctuate all that much, but it's still possible to find discounts. 

Where to Go

The prevailing wisdom regarding visits to Costa Rica during the green season is that you'll want to visit the areas with the least fluctuation in weather when compared to the dry season. Much of Guanacaste Province (especially the Nicoya Peninsula) enjoys a tropical dry climate year-round. Therefore the temperature fluctuation in many areas here is negligible, just a couple of degrees. 

That means you can visit popular Pacific coastal destinations like Nosara, Tamarindo, Playa Guiones, and more while enjoying some decent weather but without the crowds and high-season prices. You should also consider visiting the Caribbean side of the country during August. The popular village of Puerto Viejo, located near the Panamanian border, enjoys its own mini-dry season during this time, so you'll find sunny beach weather here too. 

If you come to Costa Rica at the beginning of August, and you plan on spending more than a day or two around the capital of San José, consider visiting the nearby city of Cartago. The Virgin of Los Angeles Day (Costa Rica's third-biggest religious festival after Christmas and Easter) takes place on August 2nd and is quite the sight to see (more on this below).

What to Do

If you visit the Caribbean coast you'll arrive during the middle of sea turtle nesting season. There's only one place to go during this time, and that's Tortuguero National Park, located on the northern corner of the coast. This remote protected area is only accessible by boat and plane, but if you come you can see female hawksbill, leatherback, and green sea turtles laying their eggs after the sun goes down. 

Travel further down the Caribbean coast and you'll find some great surfing on the beaches around the village of Puerto Viejo. These include Playa Cocles and Playa Negra. On the opposite Pacific side of the country, you can spot humpback whales migrating. Visit the Osa Peninsula and the marine reserve Isla del Cano and you'll not only spot whales but dolphins too. 

Whitewater rafting is also at its best during the rainy season due to the high water levels. There are a number of river throughout the country you can choose. These include the Balsa River, the Reventazon, the Sarapiquí, and more. These rivers offer rapids for all skill levels, from gentle class I to raging class V.

A unique activity is to witness the spiritual pilgrimage (known as the romería). Each year some two million locals travel by foot to the city of Cartago. From San José it's a 13-mile walk can take a couple days or longer. If you like, you can even join in the procession.

Events in August

Virgin of Los Angeles Day. On August 2nd every year scores of people make a pilgrimage to the cathedral at Cartago, where they pay their respects to the Virgin and ask for wishes to be granted. 

San Ramon Patron Saint Day. August 30 marks the Festejos Patronoles, an annual festivity held in the town of San Ramon (outside San José), and features parades, live music, and dancing.
