When to Visit: August Weather in Costa Rica

Dive into the Lush Life
Imagine this: you’re swaying in a hammock, the jungle alive with the hum of cicadas, as a warm breeze carries the scent of wet earth and blooming orchids. August in Costa Rica is a green-season gem—vibrant, wild, and wonderfully uncrowded. It’s the rainy season’s sweet spot, where showers fuel adventure and the landscapes glow with life. Sure, you’ll dodge some raindrops, but you’ll also dodge the tourist throngs. From Pacific waterfalls to Caribbean sun, here’s your guide to August in Costa Rica—weather quirks, must-dos, and all.
August Weather: Pros and Cons
August straddles the line between wet and wild, offering a taste of Costa Rica’s rainy season with a side of pura vida perks.
- Pros: The country’s drenched in green—think swollen rivers, misty forests, and fewer crowds. Rates drop for hotels and tours, making it a budget-savvy escape. The Caribbean coast teases with drier days.
- Cons: Rain is a frequent visitor, especially on the Pacific side, with muddy trails and the odd road hiccup. Some eco-lodges take a break, so planning needs a little flex.
Unlike the dry, bustling December weather in Costa Rica—perfect for beach-hopping hordes—August delivers a quieter, lusher vibe that’s all about nature’s raw beauty.
Microclimates: A Weather Tapestry
Costa Rica’s tiny footprint hides a patchwork of microclimates, and August weaves them into a vivid scene.
- Pacific Coast (Guanacaste, Samara, Tamarindo, Nosara, Montezuma, Nicoya Peninsula): Rain ramps up—10-12 inches—with afternoon showers stealing the show. Mornings might wink with sun, but highs in the upper 80s°F (30°C) keep it humid and hot.
- Central Pacific (Manuel Antonio, Quepos, Dominical, Uvita, Jacó): Daily downpours, often late-day, with temps around 85-88°F (29-31°C). The jungle’s a dripping masterpiece, though paths can get slippery.
- Caribbean Coast (Puerto Viejo, Tortuguero): A lighter touch—less rain, more sun breaks, and temps in the low 80s°F (27°C). Humidity lingers, but it’s a sweet spot this month.
- Central Valley (San José, Atenas): Mild and breezy, with highs of 75-80°F (24-27°C). Showers pop in and out, leaving plenty of dry pockets to explore.
- Highlands (Monteverde, Arenal): Cool and misty, with temps in the 60s°F (15-20°C). Steady drizzle feeds the cloud forests, but fog might veil those volcano views.
August’s weather is a pick-your-poison playground—choose your flavor and dive in.
What to Pack for August
August calls for a pack-light, rain-ready approach. Here’s what you’ll need:
- Lightweight rain jacket or poncho—your go-to for sudden showers.
- Quick-dry gear—tees, shorts, and pants that shrug off humidity.
- Waterproof hiking shoes—muddy trails demand traction.
- Swimsuit—hot springs and Caribbean waves don’t care about rain.

Pack for a jungle trek and a beach flop—August’s got both up its sleeve.
