Why the Green Season is one of the best times to visit Costa Rica
Think Costa Rica's Green Season isn't worth visiting? Think again. While most travelers automatically book their trip during the dry season, the country's lushest landscapes, most spectacular wildlife encounters and best travel deals often happen between May and November. In this guide, you'll discover why the Green Season is one of Costa Rica's best-kept secrets, what to expect from the weather, where to go, how much you can save and how to make the most of your trip.
Quick facts
The Green Season generally runs from May to November.
Rain usually falls in the afternoon or evening, leaving plenty of time to explore during the morning.
National parks are quieter, landscapes are greener and waterfalls are at their most spectacular.
Hotels, tours and rental cars are often 20% to 40% cheaper than during the peak travel season.
Some regions, especially the Caribbean coast, can even enjoy their best weather while much of the Pacific receives more rain.
What exactly is Costa Rica's Green Season?
Despite its name, the Green Season isn't simply "the rainy season." It's the time of year when Costa Rica becomes the version you've probably imagined while planning your trip: dense rainforests glowing in every shade of green, rivers flowing at full strength, waterfalls crashing through the jungle and wildlife thriving almost everywhere you look.
Locals usually refer to this period as invierno, or winter, even though daytime temperatures often stay above 77°F (25°C). Travel professionals, on the other hand, prefer the term Green Season, because it reflects what visitors actually experience. The country doesn't become gray, it becomes incredibly vibrant.
If you've ever seen breathtaking images of Costa Rica covered in mist, with tropical forests stretching to the horizon and waterfalls surrounded by lush vegetation, chances are they were taken during the Green Season.
Does it really rain all day?
Not at all, and that's probably the biggest misconception about traveling to Costa Rica between May and November.
In most regions, mornings are warm, bright and perfect for outdoor adventures. Hiking, wildlife watching, surfing or visiting national parks can easily fill the first half of your day before tropical showers develop later in the afternoon. These downpours are often intense, but they're usually short-lived, and by evening the air feels cooler, fresher and surprisingly pleasant.
Another important detail is that rain doesn't fall everywhere at the same time. Costa Rica is famous for its microclimates, meaning two destinations just a couple of hours apart can experience completely different weather on the very same afternoon.
Imagine starting your morning inside Corcovado National Park, watching scarlet macaws fly overhead while monkeys move through the canopy. By the time tropical rain begins several hours later, you're already relaxing on the terrace of your eco-lodge with a fresh cup of Costa Rican coffee, listening to the rainforest come alive around you. That's a typical Green Season day.
Travel tip: Plan outdoor activities in the morning and keep museums, cafés, hot springs or spa time for later in the day. You'll naturally adapt your itinerary to Costa Rica's tropical rhythm, instead of fighting against it.
Which regions stay sunny during the Green Season?
One of Costa Rica's biggest advantages is that weather isn't the same everywhere. Thanks to its mountains, coastlines and changing elevations, some regions remain surprisingly sunny even while others receive more rainfall.
Guanacaste, the driest part of Costa Rica
If you're looking for sunshine during the Green Season, Guanacaste is your safest bet. Home to destinations like Tamarindo, Playa Flamingo, Sámara and Nosara, this region receives significantly less rainfall than most of the country.
You'll still experience occasional tropical showers, but they're usually short, and sunny mornings are the norm. It's one of the reasons why Guanacaste remains a favorite destination for beach lovers all year long.
The Caribbean coast follows its own weather pattern
Costa Rica's Caribbean coast plays by different rules.
While September and October are often the wettest months on the Pacific coast, they're frequently among the sunniest months around Puerto Viejo, Cahuita and parts of Tortuguero. Travelers who know this often plan their itinerary accordingly, enjoying beautiful weather while avoiding the peak tourist season.
It's one of Costa Rica's best-kept travel secrets.
Arenal and the Central Valley reward early risers
Around Arenal Volcano, La Fortuna and the Central Valley, afternoon showers are common during the Green Season. Mornings, however, often offer clear views of the volcano, comfortable temperatures and excellent conditions for hiking or visiting hot springs.
Many travelers are surprised to discover that the famous cone-shaped silhouette of Arenal is often easiest to admire just after sunrise, before clouds gradually build later in the day.
Good to know: There is always a part of Costa Rica where the weather is better than somewhere else. A flexible itinerary lets you make the most of local conditions throughout your trip.
Why the Green Season offers something the dry season can't
The dry season is popular for good reason. Days are sunny, rainfall is limited and getting around the country is straightforward. But popularity comes at a price.
During the Green Season, Costa Rica reveals a different side of itself, one that many experienced travelers actually prefer.
Landscapes become spectacular
This is when Costa Rica truly lives up to its reputation.
Rainforests and cloud forests become incredibly lush, rivers fill naturally and waterfalls reach their most impressive flow. Trails feel wilder, vegetation is denser and the scenery looks exactly like the tropical paradise many visitors expect to find.
If photography is one of the reasons you're visiting Costa Rica, this is arguably the country's most beautiful season.
Wildlife becomes even more active
The Green Season also brings some of Costa Rica's most remarkable wildlife experiences.
Sea turtles arrive on beaches such as Tortuguero, Ostional and Playa Grande to lay their eggs. Humpback whales migrate along the Pacific coast. Frogs become more active after rainfall, tropical birds are easier to spot and the rainforest feels alive from sunrise to sunset.
Wildlife experience | Best time during the Green Season | Best locations |
Sea turtle nesting | July to October | Tortuguero, Ostional, Playa Grande |
Humpback whales | July to October | Marino Ballena, Golfo Dulce |
Red-eyed tree frogs | May to November | Arenal, Sarapiquí, Tortuguero |
Sloths | Throughout the Green Season | La Fortuna, Cahuita, Manuel Antonio |
Monkeys | Throughout the Green Season | Corcovado, Manuel Antonio, Tortuguero |
National parks feel more peaceful
During the peak travel season, some of Costa Rica's most famous parks become busy shortly after opening.
Visit during the Green Season and the atmosphere changes completely. Trails are quieter, wildlife is less disturbed and you'll often have spectacular viewpoints almost to yourself.
Picture yourself watching a troop of capuchin monkeys crossing the canopy in Manuel Antonio with only a handful of other visitors nearby. A few months later, that same trail could be filled with dozens of tour groups before 9 a.m.
How much money can you really save?
Choosing the Green Season isn't just about avoiding crowds. It can also make a noticeable difference to your travel budget.
Hotels and eco-lodges frequently offer discounts ranging from 20% to 40%, especially between September and early November. Properties that sell out months in advance during the dry season often have much better availability, giving you access to unique accommodations at significantly lower prices.
International flights are also generally less expensive. Depending on your departure city and travel dates, flying during the Green Season can save several hundred dollars compared with peak season fares.
Rental cars follow the same trend. Better availability, lower daily rates and more vehicle choices make this one of the best times of year to rent, especially if you're planning a self-drive itinerary across several regions.
Travel tip: Even during the Green Season, book popular eco-lodges and boutique hotels a few weeks ahead. The country's most sought-after properties can still fill up quickly, particularly around Arenal and the Osa Peninsula.
Why renting a 4WD makes even more sense during the Green Season
Having your own vehicle is always one of the best ways to explore Costa Rica. During the Green Season, it becomes even more valuable because it gives you the flexibility to adapt your itinerary to local weather conditions, discover lesser-known places and travel at your own pace.
Flexibility becomes your biggest advantage
Weather conditions can vary from one region to another, sometimes within the same day. Having your own vehicle means you can easily adjust your plans, leave earlier for an excursion or spend an extra night in a destination where the forecast looks better.
Instead of being tied to shuttle schedules or organized tours, you're free to follow the sunshine.
Some destinations are easier to reach with a 4WD
Many of Costa Rica's main tourist attractions are accessible with a standard vehicle. However, some remote beaches, mountain lodges and rainforest ecolodges become quite challenging after heavy rainfall.
If your itinerary includes places such as the Osa Peninsula, rural areas around Monteverde, or unpaved roads leading to nature lodges, renting a 4WD is highly recommended.
That doesn't mean every traveler needs one. The right vehicle depends much more on your itinerary than on the season itself.
Driving tip: Before heading to remote areas, check local road conditions and avoid crossing rivers unless you're familiar with the route. Water levels can rise quickly after tropical storms.
How should you prepare for a Green Season trip?
Traveling during Costa Rica's Green Season doesn't require heavy rain gear or complicated planning. A few simple adjustments are usually enough to enjoy everything the country has to offer.
1. Pack light, but bring the right gear
Forget bulky jackets and waterproof boots. A lightweight rain jacket or compact poncho is usually all you need. Breathable clothing, comfortable hiking shoes and quick-drying fabrics are much more useful than heavy layers, since temperatures remain warm throughout the year.
2. Plan outdoor activities in the morning
Costa Rica naturally sets the rhythm of your day. Early mornings are ideal for hiking, wildlife watching, surfing, zip-lining or visiting national parks. If rain arrives later in the afternoon, it's the perfect excuse to relax at your hotel, enjoy a coffee overlooking the rainforest or unwind in one of the country's famous hot springs.
Many experienced travelers end up preferring this slower pace.
3. Check regional weather forecasts
Looking at the weather for "Costa Rica" isn't enough. Instead, check forecasts for the specific regions you'll be visiting. Conditions in Liberia, La Fortuna, Puerto Viejo and San José can be completely different on the same day.
Apps such as Windy or The Weather Channel provide much more accurate regional forecasts than a single national weather report.
4. Book unique accommodations ahead of time
Although the Green Season attracts fewer visitors overall, Costa Rica's most popular eco-lodges still fill up surprisingly quickly. If staying in a rainforest lodge, a boutique hotel overlooking Arenal Volcano or an eco-retreat on the Osa Peninsula is high on your wish list, reserve your accommodation a few weeks in advance.
Common mistakes to avoid during the Green Season
Many travelers hesitate because of outdated assumptions about Costa Rica's rainy season. In reality, avoiding these common mistakes can make a huge difference.
Assuming every day will be rainy: Afternoon showers are common, but they rarely prevent you from enjoying a full day of activities.
Staying in only one region: Costa Rica's microclimates are one of its greatest strengths. If the weather changes in one area, another region may be enjoying sunshine.
Overpacking: Heavy waterproof clothing usually stays at the bottom of your suitcase. Lightweight, quick-drying clothes are much more practical.
Booking everything at the last minute: The Green Season is quieter, but Costa Rica's best eco-lodges and boutique hotels remain popular throughout the year.
Choosing the wrong vehicle: Don't rent a 4WD simply because it's the rainy season. Choose the vehicle that matches your itinerary, not the weather forecast.
