🌎 What’s the Weather Like in August?

Costa Rica’s weather in August varies by region, thanks to its diverse ecosystems and microclimates. Here's what travelers can expect:

Pacific Coast (Guanacaste, Nicoya, Tamarindo):
This northwest region is drier than the rest of the country, even in August. Expect sunny mornings, occasional afternoon showers, and warm temperatures around 85–90°F (29–32°C). Ideal for beach getaways, surfing, and sunsets.

Central Pacific (Manuel Antonio, Dominical, Uvita):
Known for its lush tropical forests and beaches, this area sees more consistent rain, but mornings are often clear and perfect for excursions. Temperatures range from 78–88°F (25–31°C). It's a hotspot for wildlife and waterfall hikes.

Central Valley (San José, Heredia, Cartago):
Mild and spring-like year-round, the Central Valley sees cool mornings and rainy afternoons in August. Temps hover between 65–77°F (18–25°C) — great for coffee tours, markets, and cultural experiences.

Caribbean Coast (Puerto Viejo, Tortuguero):
The Caribbean side bucks the national trend — August is actually one of its driest months. Expect sunny days and warm temperatures around 75–85°F (24–29°C). It’s an excellent time to visit Tortuguero for sea turtle nesting season.

Northern Zone & Highlands (Arenal, La Fortuna, Monteverde):
Expect cooler temps (60–75°F / 16–24°C) and misty, cloud-kissed mornings. August brings occasional rain, but it’s also peak time for lush jungle adventures, hot springs, and wildlife watching.
