Is August Right for You?
Weigh the advantages and considerations before booking
- + Green season turns Costa Rica into a photographer's playground. Waterfalls you've only seen as dry-season trickles now roar down 90-meter (295-foot) drops at La Fortuna, and the entire landscape glows an almost artificial emerald that locals call 'el verano verde'
- + Wildlife viewing hits its stride in August. Sloths move more with newborns clinging to their backs, the whale migration brings humpbacks within 200 meters (656 feet) of shore at Marino Ballena, and turtle nesting at Tortuguero peaks nightly around 10 PM
- + Room rates plummet 40-60% from December-April pricing. The same beachfront bungalow that demands six-month advance booking in February becomes available with two weeks' notice, and you'll own the Pacific beaches until 11 AM
- + Afternoon rains set the rhythm for cultural immersion. Locals build their entire day around the 2-4 PM downpours, keeping markets busy until rain hits, and sodas (local diners) overflow with families sharing gallo pinto while waiting out the storm
- − Road conditions deteriorate fast. What takes 2 hours on Highway 34 in March stretches to 4 hours in August when sudden washouts turn paved sections into single-lane rivers, and the mountain road to Monteverde becomes a muddy slip-and-slide demanding 4WD
- − Beach expectations need recalibrating. The Pacific coast's typical turquoise water turns brown from river runoff, and swimming becomes dangerous at beaches like Dominical where rip currents strengthen with increased rainfall
- − Mosquito season peaks. August brings the highest concentration of these relentless insects, around Manual Antonio's mangroves and Tortuguero's canals, where you'll need repellent every hour from 5 PM to sunrise
Best Activities in August
Top things to do during your visit
August turns Costa Rica's rivers into class III-IV rapids that remain tame the rest of the year. The Pacuare River becomes a 29-kilometer (18-mile) adrenaline rush through virgin rainforest, with waterfalls cascading directly into the river. Water levels hit the sweet spot - high enough for excitement, low enough for safety.
Tortuguero's beaches become a prehistoric theater after 9 PM when 300-kilogram (660-pound) green turtles haul themselves ashore to nest. August is peak season - you'll witness 15-20 nesting attempts nightly, with the moonlit beach resembling a living conveyor belt of ancient mariners.
August marks the transition between harvests, when coffee cherries ripen from green to deep red across the Central Valley's volcanic slopes. Tours at 1,200-meter (3,937-foot) elevations include hands-on cherry picking, traditional processing demonstrations using 100-year-old equipment, and tastings where you'll learn to distinguish chocolate notes from Tarrazú versus citrus hints from Tres Ríos.
Humpback whales migrate 8,000 kilometers (4,971 miles) from Antarctica to Costa Rica's warm waters for August mating season. The whales breach within 200 meters (656 feet) of boats in Marino Ballena National Park, performing 15-minute acrobatic displays that continue until sunset.
August clouds create dramatic photography at Arenal Volcano, where morning mist lifts to reveal 1,670-meter (5,479-foot) peaks. The rainforest trails to Cerro Chato's crater lake become muddy adventures where howler monkeys provide natural soundtrack, and natural hot springs feel more intense when air temperature drops during afternoon rains.
August's morning mist creates ethereal cloud forest conditions in Monteverde, where 150-foot (46-meter) tall strangler figs become launching platforms. The humidity makes wildlife more active - expect close encounters with three-toed sloths feeding at eye level and resplendent quetzals performing mating displays.
August Events & Festivals
What's happening during your visit
This 10-day celebration transforms Heredia's central park into a cultural show - traditional masquerade dancers wear 3-meter (10-foot) tall paper-maché heads, while ox-drawn carts parade through streets lined with food stalls serving tamales wrapped in banana leaves. The highlight happens at midnight on August 4th when fireworks launch from the 19th-century church tower.
Costa Rica's most important religious pilgrimage sees 2 million faithful walk 22 kilometers (14 miles) from San José to Cartago's basilica. The human river of pilgrims flows along the Interamericana Highway starting at midnight, with many completing the journey barefoot as penance while singing traditional hymns.
