Here’s your guide to choosing the perfect time for your visit, whether you’re seeking sunny days, fewer tourists, or the best of Costa Rica’s natural beauty!

Costa Rica's Seasons: Dry vs. Rainy

Costa Rica is a tropical country, so instead of the four seasons, you’ll experience two primary seasons: the dry season and the rainy season.

  • Dry Season (High Season): Late November to April marks Costa Rica's dry months. With clear skies, sunny days, and lower chances of rain, this is considered the peak season. It’s an ideal time for families who love beach time, outdoor activities, and wildlife viewing.

  • Rainy Season (Green Season): From May to early November, the rainy season brings lush greenery, fewer tourists, and lower prices. For nature lovers, it’s a great time to experience Costa Rica’s vibrant ecosystem with fewer crowds. Rain usually falls in the late afternoon or evening, leaving the mornings free for adventures.

What’s the Best Time of Year to Visit Guanacaste?

1. The Dry Season (December to April)

The dry season is the most popular time to visit Guanacaste. With clear skies, warm temperatures in the high 70s, and stunning beach days, it’s perfect for families looking to relax on the Pacific coast. The climate in Guanacaste is pretty consistent, so you can always count on warm weather! Many North Americans head south during the winter, so there are more tourists, and you should consider booking your tours and excursions ahead of time. Although there are always things you can book last minute if that's more your style!

  • Beach Lovers: Visit Playa Conchal, a favorite spot on the Gold Coast, or explore the Nicoya Peninsula for some of the most beautiful and less crowded beaches.

  • Wildlife Viewing: This is the best time to see olive ridley sea turtles nesting at Ostional Wildlife Refuge or humpback whales off the Pacific Ocean coast.

  • Outdoor Adventures: Enjoy hiking, hot springs, and trips to Santa Rosa National Park. Guanacaste is a great climate for activities like ziplining, surfing, and exploring UNESCO World Heritage sites.

Notable Exception: While the dry season offers the best weather, it also comes with higher prices and more tourists, particularly around New Year and during school holidays.

2. The Green Season (May to Early November)

If you prefer a quieter less touristy time, a good time to visit is from May to early November. The green season offers fewer tourists, lower prices, and incredible natural beauty. While you’ll encounter rainy afternoons, and more clouds in the sky, mornings are often sunny and cooler temperatures (relatively speaking!) can make outdoor adventures more comfortable. With cloud coverage, your family will likely have more stamina to hang out on the beach, or explore tide pools without having to seek shade from the hot tropical sun. My family loves spending time in Costa Rica in September and October. You have to make fewer reservations ahead of time and can be more spontaneous, since everything is just less busy. A trade-off is that some tour operators and businesses close for a few weeks during this time to take some vacation time during the low season. 

  • Nature Lovers: Rain transforms the Guanacaste Province into a lush, green paradise. Explore national parks like Santa Rosa and spot green sea turtles.

  • Fewer Crowds & Lower Prices: The tourism industry slows down during this period, making it easier to find deals on accommodations, including luxury rentals with private pools.

  • Beach Days: Despite rainy days, the beaches still have great weather in the mornings. Playa Conchal and the surrounding Pacific coast are quieter during this season.

Tip: Late November is a good idea for a visit as you’ll catch the beginning of the dry season with fewer crowds!

Travel Tips for Guanacaste, Costa Rica

  • Transportation: While Costa Rica roads can be tricky driving in some spots (picture narrow roads with potholes), most of the region is well maintained and easily accessible by care via Liberia International Airport or San José. Liberia International Airport is the more convenient option for reaching Guanacaste quickly, with direct access to popular destinations like Playa Conchal, Tamarindo, Playa Flamingo, and the Nicoya Peninsula, as well as nearby national parks. If you plan to rely on public transportation, be prepared for buses that may take longer. For greater flexibility, consider renting a 4x4 vehicle to explore off-the-beaten-path (or even well traveled) spots with ease. Renting a car in Costa Rica provides the ultimate flexibility, but you do need to be aware of the cost and process for insurance.

  • Cash & Credit Cards: Bring a mix of credit cards and local currency (Costa Rican colón) for convenience. While larger hotels, restaurants, and shops accept cards, many small vendors, local eateries, and markets prefer cash. ATMs are readily available in towns, but it’s always a good idea to carry some cash for tips, entrance fees, or stops in remote areas where cards may not be accepted. The CRC is the local currency, but US Dollars are widely accepted, and many vendors quote prices in USD for tourists.

  • Pack for Rain: If visiting during the green season, expect occasional rainy afternoons and showers. Pack lightweight, quick-dry clothing, waterproof jackets, and sturdy, closed-toe shoes for muddy paths. A small umbrella and reusable water-resistant bags for electronics will also come in handy. Don’t let the rain deter you—the mornings are often sunny, and the rain only adds to the region’s lush greenery.

  • Beaches: Don’t miss Guanacaste’s stunning beaches, including Playa Avellanas, Playa Hermosa, and Playa Conchal known for its crystal-clear waters and crushed shell shoreline, and those along the Nicoya Peninsula. Each beach offers something unique, from calm waters perfect for families to adventurous surf spots. Early mornings are often the best time for beach outings, while evenings provide spectacular sunsets over the Pacific Ocean.

  • Local Authorities: Follow local advice and guidelines, especially when it comes to wildlife viewing. Whether you’re observing olive ridley sea turtles nesting at Ostional Wildlife Refuge or watching humpback whales, keep a safe distance to protect the animals and their habitats. Many tours are operated by licensed guides who ensure both safety and an incredible experience. When driving, respect local speed limits and watch for wildlife crossing the road, particularly in rural areas. Watch out motorcycles and scooters, and motorists who pass on the left (even when you are in the left lane waiting to turn left!). Always keep an eye on what is coming up behind you and be ready for defensive driving. Overall, the speed of traffic is not very fast, just because of the size of the roads so if you are mindful and defensive, driving in Costa Rica is totally doable!

  • Stay Connected: While cell coverage is reliable in larger towns and tourist areas, some remote spots may have weaker signals. Consider purchasing a local SIM card or eSIM for better connectivity during your travels.

  • Safety Tip: Costa Rica is generally very safe for families, but be mindful of your belongings, especially on beaches and in crowded tourist areas. Use hotel safes for valuables and keep an eye on personal items while exploring.
