Rainy Season in Costa Rica 2026: Planning a Green Season Trip to Jaco
If you are looking at dates during the rainy season in Costa Rica in 2026, you are probably weighing two things: whether the weather will ruin the trip, and whether quieter, greener months are worth it. For Jaco and the Central Pacific coast, the answer for most groups is that a rainy-season trip works well, as long as you plan your days around the weather instead of against it.
This guide explains what the green season usually looks like around Jaco, how to build a daily schedule that fits it, and why the house you choose matters more when you may spend some afternoons indoors.
When Is the Rainy Season in Costa Rica?
Costa Rica has two broad seasons. The dry season runs roughly from December to April, and those months are the busiest and most expensive dates in Jaco. The rainy season, which locals and tourism businesses often call the "green season," covers most of the rest of the year, roughly May through November.
Weather is never identical from one year to the next, and no one can promise what 2026 will bring. Patterns can shift, and climate events such as El Niño or La Niña can make a season wetter or drier than usual. Before you book, check the outlook from Costa Rica's national weather service, the Instituto Meteorológico Nacional (IMN), and check again a week before you travel.
A Typical Green Season Day on the Central Pacific
On the Central Pacific coast, many rainy-season days follow a familiar pattern:
- Morning: often bright and sunny, the best window for the beach, surfing, fishing and tours.
- Afternoon: clouds build, and showers or thunderstorms may arrive.
- Evening: rain often eases, leaving cooler air for dinner and nightlife.
This is a tendency, not a rule. Some days stay dry and some stay grey. Plan as if the morning is your most reliable time outdoors, and keep the afternoon flexible.
The Wettest Months
Toward the end of the green season, usually around September and October, rain on the Pacific side tends to be heavier and can last longer. If your dates are flexible and weather is your main concern, the early green season (May to July) is generally a gentler choice than the last stretch before the dry season returns.

Why Groups Still Choose Jaco in the Green Season
Greener Landscapes and Quieter Beaches
The rain turns the hills behind Jaco and the forest around Herradura bright green. Beaches and restaurants are usually less crowded than in peak season, and it is often easier to get a table for a large group.
More Choice of Villas and Dates
Because the dry season is the busiest time of year, green-season dates often give you more choice of homes. If you want one of the larger villas for 16 to 20 guests, such as Casa Maverick or Casa Amarillo, green-season dates can be easier to secure. Rates change by date, so ask us for a direct quote rather than assuming a discount. [CONFIRM: whether Jaco Casa offers lower green-season rates or minimum-stay changes]
Surf Conditions
Many surfers like the green season on the Pacific coast because of more frequent swells. Conditions change daily, so check a surf forecast and read our guide to surfing Jaco Beach before you paddle out.
How to Plan Your Days Around the Rain
Put Big Activities in the Morning
Book sportfishing charters from Los Sueños Marina in Herradura, ATV tours, ziplining and surf lessons for the morning where you can. Tour operators may change times or cancel trips for safety when weather turns. Ask each operator about their weather policy before you pay. [CONFIRM: whether Jaco Casa can book or recommend tour operators]
Make the House the Afternoon Plan
During the green season, the villa becomes the venue for the afternoon. That is when features such as a game room, a covered outdoor area or a large living room really count. Casa Marlin has a game room, a jacuzzi and a private pool, and VTB14 has a private pool and a hot tub with marina views.
A private chef can make a rainy afternoon easy: a long late lunch or an early dinner at home instead of a wet drive into town. See private chef services at Jaco Casa for how it works.
Leave Room for Changes
Avoid packing every hour of every day. Keep at least one flexible afternoon per trip so you can move an activity if a storm rolls in.
Getting to Jaco in the Rainy Season
Jaco is roughly a 1.5 to 2 hour drive from San José International Airport (SJO). Heavy rain can slow traffic, so allow extra time and avoid booking tight connections on your arrival day. A private driver for the whole group is usually simpler than several rental cars, and we can arrange drivers if you send us your arrival times.
Packing List for the Green Season
| Item | Why it helps |
|---|---|
| Light rain jacket | Short showers are common; heavy coats are unnecessary in the heat |
| Quick-dry clothing | Cotton dries slowly in humid air |
| Sandals or water shoes | Streets and paths can be wet after a storm |
| Dry bag or waterproof phone case | Useful for boats, tours and the beach |
| Insect repellent | Mosquitoes can be more active after rain |
| Reef-safe sunscreen | Morning sun is still strong |
Choosing the Right Villa for a Green Season Stay
When some time is spent indoors, look for:
- Covered outdoor space so you can stay by the pool during light rain.
- Air conditioning for comfortable sleep in humid weather.
- Space to gather: a large living room, a dining table that seats the whole group and a kitchen big enough for a chef.
- Location that matches your plans. Downtown condos such as BWP 703 keep restaurants within a short walk, while homes in Los Sueños, such as Delmar, are close to the marina.
