August Weather in Costa Rica
Is August Right for You?
Advantages
- Green season rates drop 35-50% on accommodation - beach hotels in Manuel Antonio that command $400+ in January drop to half that in August
- Turtles nesting at Ostional and Playa Grande - witness thousands of olive ridleys arriving in synchronized arribadas under full moons
- Rivers run high and waterfalls thunder - the 70m (230 ft) La Fortuna waterfall becomes twice as powerful as dry season
- Surf swells hit the Pacific coast with consistent 1.5-2.5m (5-8 ft) waves at Tamarindo and Santa Teresa
Considerations
- Afternoon thunderstorms roll in like clockwork at 2-3pm, turning jungle paths into rivers and washing out unpaved roads
- Cloud cover obscures Arenal volcano's peak 60% of the time - plan dawn visits if you want that postcard-perfect cone
- Humidity hits 85% on Caribbean coast, making hiking feel like breathing through a wet towel
Best Activities in August
Tortuguero Canal Wildlife Tours
August transforms Tortuguero's waterways into a mirror reflecting caimans, three-toed sloths, and all seven species of herons. Morning boat tours beat the 2pm thunderstorms, and the higher water levels let narrow channels that are too shallow in April open up to explore deeper into the rainforest.
White Water Rafting on Pacuare River
August's rains supercharge the Pacuare to Class III-IV rapids through 25km (15.5 miles) of virgin rainforest. The water runs warm enough (24°C / 75°F) that you won't need wetsuits, and afternoon storms enhance the experience - nothing like paddling through rain curtains while howler monkeys protest from the canopy.
Coffee Farm Tours in Naranjo Highlands
Harvest season starts in August - you'll see pickers hand-selecting crimson cherries while morning mists roll through 1,200m (3,937 ft) elevations. The cooler mountain climate (20°C / 68°F) provides relief from lowland humidity, and fresh-roasted coffee tastes completely different when you're standing among the trees that produced it.
Snorkeling at Isla del Caño Biological Reserve
August's plankton blooms attract massive schools of jacks, eagle rays, and the occasional humpback whale. Visibility drops slightly to 15-20m (49-66 ft) but marine life density triples - think swimming through aquarium tanks rather than empty blue water.
Chocolate Making Workshops in Puerto Viejo
August humidity is perfect for cacao fermentation - you'll smell the sweet-tart aroma of beans drying on wooden racks before grinding them on stone metates. Caribbean weather means afternoon storms, but workshops run in covered outdoor kitchens where rain on tin roofs adds percussion to the experience.
August Events & Festivals
Dia de la Virgen de los Angeles
August 2nd brings 2 million pilgrims walking to Cartago's basilica, transforming the 22km (13.7 mile) route from San Jose into a moving street party of music, food stalls, and candle-carrying faithful. The real magic happens overnight - join the final 3km (1.9 mile) stretch at 3am when candlelight flickers across colonial stone streets.
Fiestas Civicas de Nicoya
Last week of August explodes with traditional bull riding (no blood), marimba bands, and chicharron contests in Nicoya's central plaza. Locals spend months preparing - sample sopa de guanacaste served from massive cauldrons while dancers in embroidered costumes perform the Punto Guanacasteco.
