What to Do in Costa Rica When It Rains

Rain is part of Costa Rica. The country's forests are green for a reason, and much of the year brings regular showers, especially during the green season from about May to November on the Pacific side. For many travellers this is a great time to visit: prices drop, crowds thin out and the landscapes are at their most lush. The key is knowing how to plan your days around the weather and having a list of good rainy-day options ready.

In much of Costa Rica, green-season rain follows a pattern. Mornings are often sunny or partly cloudy, clouds build around midday, and heavy showers arrive in the afternoon or evening. That means you can often enjoy outdoor activities early and save indoor or rain-friendly ones for later.

Weather varies by region, though. The Caribbean coast has a different pattern from the Pacific, and mountain areas like Monteverde can be misty any time of year. It is always worth checking local forecasts and asking your hotel what to expect.

Few things are better on a rainy afternoon than sitting in warm volcanic water while the rain falls around you. The Arenal area has many hot spring options, from simple natural pools to resorts with landscaped gardens. Guanacaste's Rincón de la Vieja area also has thermal pools and mud baths. The rain does not matter when you are already in the water.

Coffee and cacao tours are among the best rainy-day activities because much of the experience happens under cover. You learn how beans are grown, harvested, dried and roasted, and you usually get to taste the results. Coffee tours are common in the Central Valley and Monteverde, while cacao farms are found in several regions, including the Caribbean side.

For adventurous travellers, rain can actually improve some activities. White-water rafting rivers such as the Pacuare and the Sarapiquí often have better water levels in the wetter months. You are going to get soaked anyway, so a little rain makes no difference. Always book with an established operator that provides safety equipment and trained guides.

Waterfalls are at their most impressive in the green season. With a good rain jacket and shoes with grip, a morning waterfall hike can be a highlight. Avoid swimming at the base of a waterfall after heavy rain, as currents and falling debris can be dangerous, and follow local advice on trail closures. Triplarks

If you are in the Central Valley, San José has several museums that are ideal for a wet day. The collections of pre-Columbian gold and jade offer a fascinating look at the cultures that lived in the region long before the Spanish arrived. The National Theatre, with its ornate interior, is worth a visit too, and guided tours are often available.

Many animals do not mind the rain at all. Frogs are more active in wet conditions, and birdwatching can be excellent just after a shower. Guided walks in national parks and private reserves continue in light rain, and guides usually carry umbrellas or ponchos. Night tours are especially good in the green season, when frogs and insects are out in force.

Hanging bridge parks around Arenal and Monteverde let you walk through the forest canopy on suspended walkways. Light rain and mist add atmosphere, and the forest smells and sounds come alive. Only heavy storms or lightning would make it worth postponing.

Cooking classes are a fun way to spend a rainy afternoon. You might learn to make gallo pinto, tortillas, picadillo or a Caribbean rice and beans with coconut milk, then sit down to eat what you have cooked. Many hotels and small local businesses offer classes on request.

Rescue and rehabilitation centres care for injured and orphaned animals, such as sloths, birds and monkeys. Visits are usually guided, and many have covered areas. They are a good way to see wildlife up close while supporting conservation work.

• Pack a lightweight rain jacket, quick-dry clothing and a dry bag for electronics.
• Plan longer drives for the morning, when roads are drier and visibility better. More information on regional conditions is available from the official Visit Costa Rica site.
• Keep afternoons flexible and have one or two indoor ideas ready.
• Choose accommodation with a covered terrace or common area, so you can relax outside even when it pours.

Rain rarely ruins a trip to Costa Rica. It just changes the rhythm. For more ideas across the whole country, including beaches, volcanoes and adventure tours for sunny days, it is worth reading a full country guide before you go.
