Costa Rica is one of the most geographically diverse countries on Earth — in a single trip you might hike volcanic rainforest in Arenal, surf in Tamarindo, walk canopy bridges in Monteverde cloud forest, and snorkel off Manuel Antonio’s coast. Each environment demands different clothing.
Costa Rica Climate Zones
- Pacific Coast beaches: Hot and sunny in dry season (Dec–Apr), hot and wet in green season (May–Nov)
- Caribbean Coast: Warm and rainy almost year-round. High humidity always.
- Arenal Volcano: Hot and wet — rain arrives most afternoons year-round
- Monteverde Cloud Forest: Cool (15–20°C), misty, frequently wet — genuinely chilly
What to Wear at the Beach (Tamarindo, Nosara, Manuel Antonio)
- Swimwear at the beach and everywhere near the beach
- Board shorts or bikini + rash guard for surfing (Costa Rica’s Pacific sun is intense)
- Sundress, shorts, and casual tops for town
The rash guard matters: a lightweight UV-protective swim top prevents both sunburn and rash from board contact.
What to Wear in the Rainforest
Arenal Volcano
- Moisture-wicking long-sleeve shirt (sun + bug protection)
- Quick-dry hiking trousers or moisture-wicking shorts
- Waterproof hiking boots with good grip
- A lightweight waterproof jacket (rain arrives fast)
- Swimwear for the hot springs
Monteverde Cloud Forest
Most Costa Rica visitors are underdressed for Monteverde. The altitude (1,440m) makes it genuinely cool. People in t-shirts and shorts are visibly uncomfortable here.
- Lightweight to midweight fleece or down jacket
- Long-sleeve base layer
- Full-length trousers
- Waterproof jacket
- Waterproof hiking boots with grip (suspension bridges are slippery)
Packing for Costa Rica’s beaches without bringing a fleece for Monteverde is the most common packing mistake in the country.
What to Wear for Adventure Activities
Zip-Lining
- Closed-toe shoes — sandals prohibited at most operators
- Fitted clothing — loose scarves and baggy clothing can catch in equipment
- Secure hair tie for long hair
Rafting
- Quick-dry shorts and t-shirt (you will get soaked)
- Secure sandals with a heel strap, or water shoes

Frequently Asked Questions
What is the dress code in Costa Rica?
Costa Rica is secular and casual with no significant religious dress codes. The only “dress codes” are practical: proper footwear for hiking and zip-lining, fitted clothing for adventure activities.
Do I need waterproof gear even in dry season?
Arenal and the Caribbean coast have rain year-round. Monteverde is misty year-round. A packable waterproof jacket is worth having regardless of season.
