The Best Time to Visit Jacó: An Insider's Seasonal Guide

Deciding on the best time to visit Jacó, Costa Rica, can feel like choosing between two versions of paradise. Do you prefer endless sunny days perfect for lounging on the beach, or lush, vibrant landscapes brought to life by afternoon showers? The truth is, there is no single "best" time—it all depends on the adventure you're seeking.

As local experts who live and breathe Jacó, we're here to give you an insider's look beyond the standard travel advice. We'll break down the Jacó weather by month, what you can expect from our two main seasons, and how to match your travel dates to your dream vacation, whether it's landing a trophy fish, surfing the perfect wave, or exploring a thriving rainforest.

December to April: The Peak Dry Season

This period is what most people picture when they think of a tropical getaway. From mid-December through April, Jacó and the neighboring Los Sueños area experience their driest, sunniest weather. Expect blue skies, lower humidity, and a vibrant atmosphere as travelers from around the globe arrive to soak up the sun.

Why Tourists Flock to Jacó This Time of Year

The appeal of the dry season is easy to understand. With minimal rain, every day is a beach day. The consistent sunshine makes it the perfect time for sunbathing, swimming, and enjoying outdoor dining with stunning sunsets. The energy in town is buzzing, with streets alive with people exploring shops, restaurants, and nightlife. This is the peak tourist season, so you can expect a lively environment and plenty of opportunities to meet fellow travelers. The reliable weather makes it ideal for planning activities like ATV tours and zip-lining without worrying about rain delays.

Fishing Opportunities in the Dry Season

For anglers, the dry season is prime time for offshore sport fishing. The calm seas and favorable currents create world-class conditions. This is the peak of the Sailfish season, with boats often reporting double-digit releases in a single day. You will also find an abundance of Marlin—both Blue and Striped—cruising the deep blue waters. Inshore, the fishing is equally exciting, with Roosterfish and Cubera Snapper providing thrilling fights near the rocky coastlines. The consistent Jacó fishing seasons during these months make it a magnet for serious anglers.

May to November: The Lush "Green Season"

While many travel guides call this the "rainy season," we locals prefer the term "Green Season." Starting in May, afternoon showers begin to roll in, transforming the landscape from golden brown to a thousand shades of brilliant green. The Costa Rica Green Season is a time of renewal, when the rainforests come alive and the entire region feels incredibly lush and vibrant.

The Secret of the Green Season in Jacó

Here’s the insider secret: the Green Season doesn't mean non-stop rain. Typically, mornings are bright and sunny, perfect for your planned activities. The rain usually arrives in the mid-afternoon for a few hours, offering a refreshing break from the heat and a perfect excuse for a siesta or a coffee at a local café. The clouds often part just in time for a spectacular, dramatic sunset.

This season also means fewer crowds and often lower prices on accommodations. It offers a more tranquil, laid-back experience of Jacó, allowing you to connect more deeply with the natural beauty of Costa Rica.

Top Green Season Activities

The Green Season is the heart of the surfing season in Jacó. Swells from the southern hemisphere deliver consistent and powerful waves, making it a paradise for surfers of all levels. The rain also feeds our majestic waterfalls, turning them from trickles into roaring cascades. A hike to a waterfall during this time is an unforgettable experience.

Fishing remains excellent, with the bite for Yellowfin Tuna and Dorado (Mahi-Mahi) heating up. The afternoon rains wash nutrients into the ocean, triggering a feeding frenzy that anglers can take full advantage of. It’s also a fantastic time for birdwatching, as many species are more active in the cooler, wetter conditions.

September & October: A Special Note on Your Fishing Trip

While September and October are technically the rainiest months of the Green Season, they hold a special allure for dedicated anglers. Don't let the forecast deter you. These months are often considered the absolute best for Marlin fishing. The offshore conditions can still be fantastic, and the giants of the deep are frequently biting.

If you're planning a trip focused on sport fishing, check out our detailed fishing reports for these months. You’ll find that the rewards are well worth packing a rain jacket. Offshore adventures often enjoy sunny weather while the rain remains concentrated over the coast in the afternoons.

• ☀️ For Guaranteed Sun & Social Buzz: Book your trip between December and April. It's ideal for first-time visitors and those whose priority is beach time.
• 🌿 For Lush Landscapes & Epic Surf: Choose the Green Season, from May to August. You'll get the best of both worlds—sunny mornings and refreshing afternoon rains.
