Best Time to Go to Costa Rica

Dry season, green season, and how to pick the right months for your kind of trip.

The best time to go to Costa Rica is December through April if you want dry, sunny beach weather, and May through November if you want green landscapes, fewer crowds, and lower prices. Here in Guanacaste, the driest region of the country, even the rainy months are gentler than most visitors expect.

We live and work in Playas del Coco year round, managing about 40 vacation rentals and helping buyers tour homes in every month of the calendar. So this is not a guess from a travel desk abroad. Here is how the seasons actually work, and how to match the best time to go to Costa Rica with what you want from the trip.

What are Costa Rica's two seasons?

Costa Rica does not have four seasons. It has two: the dry season (Ticos call it verano, or summer) and the rainy season (invierno, which marketers renamed the green season, and honestly the name fits). According to the official Costa Rica tourism board, the dry season on the Pacific side runs from December to March, with April as a transition month, and the rains run from May to October, with November as the other transition.

Temperatures barely move all year. On the Guanacaste coast you can expect hot days in the high 80s to low 90s Fahrenheit in any month. What changes is the rain, the crowds, and the prices.

What is the dry season like (December to April)?

This is high season, and it earns the name. From late December through April, rain in Guanacaste is rare. Skies stay blue for weeks at a time, the ocean is calm in the mornings, and every day is a beach day.

What to expect if you come in these months:

• Reliable sunshine, which is why snowbirds from the US and Canada fill the coast from January through March.
• Peak pricing on flights, hotels, and vacation rentals, especially around Christmas, New Year's, and Semana Santa (Holy Week, the week before Easter, which lands in March or April depending on the year).
• Steady seasonal winds in the early months, which sailors and kitesurfers love and which keep the heat comfortable.
• A browner landscape by March. Guanacaste's tropical dry forest drops its leaves late in the season. It is still beautiful, but it is not the postcard-green Costa Rica some people picture.

That last point is the honest tradeoff nobody mentions. If you want emerald hillsides and full waterfalls, the end of dry season is the wrong time. If you want zero rain risk for a wedding or a family beach week, it is exactly the right time.

One practical note for high season: book early. Our best-located rentals in Coco and Ocotal fill up months ahead for the December holidays and February, and the closer you get, the fewer choices you have. If you are planning a first scouting trip, our Costa Rica packing list covers what to bring in either season.

What is the green season like (May to November)?

The green season gets an unfair reputation. Rain here does not usually mean gray, wet days. The typical pattern on the Pacific coast is a sunny morning, clouds building after lunch, a heavy shower in the late afternoon or evening, and then it clears. You plan your beach time and tours for the morning and you rarely lose a full day.

What to expect:

• Lower prices. Rentals, hotels, tours, and often flights cost noticeably less than in high season, and availability is wide open.
• Green everything. The hills around Coco turn from brown to deep green within weeks of the first rains in May.
• Fewer people. Restaurants are relaxed, beaches are quiet, and you see more of how the town actually lives.
• September and October are the wettest months on the Pacific side. If you are rain-averse, aim for May through August instead, which many locals consider the sweet spot: green hills, morning sun, low-season prices.

The tradeoffs, stated plainly: afternoon plans can get rained out, some dirt roads get rough, and a few tour operators slow down in October. Bring a dry bag and a flexible attitude and the green season will treat you well.

Does the region change the answer?

Yes, more than most first-time visitors realize. Costa Rica is small, but it is a country of microclimates.

• Guanacaste (where we are) is the driest region in the country. Even in the rainy months, Playas del Coco gets less rain than the Caribbean side or the southern Pacific. It is the safest bet for beach weather almost any month.
• The Caribbean coast runs on its own calendar. The tourism board notes it has no defined dry season at all, but its drier windows fall in February to March and September to October, almost the mirror image of the Pacific.
• The mountains and cloud forest (Monteverde, the central valley) are cooler and mistier year round. Pack a layer.

So a September trip that would be soggy in Manuel Antonio can be lovely in Puerto Viejo, and a Coco beach week works in far more months than the brochures suggest. For more on the landscape and animals around us, see our guide to the wildlife of Guanacaste.

When should you go for whales and turtles?

If wildlife is the point of the trip, the calendar matters more than the weather.

Humpback whales: Costa Rica's Pacific coast gets two separate migrations. Southern hemisphere humpbacks arrive roughly July through November, and northern hemisphere whales visit December through April. The best viewing is generally August through October along the southern Pacific coast around Uvita and the Osa Peninsula.

Sea turtles: Olive ridley turtles nest at Ostional, a couple of hours south of Coco, in mass arrivals called arribadas. They happen year round, but the peak runs August through December, timed around the new moon. Seeing thousands of turtles come ashore in one night is one of the great wildlife experiences in the country, and it happens in the so-called low season.

When is the best time to visit if you are house hunting?

We tell serious buyers the same thing every year: come in the green season if you can. Three reasons.

First, you see properties honestly. Any house shows well in February. A May-to-November visit shows you how a roof, a driveway, and a road handle real rain, which matters when you are buying in the tropics.

Second, you get more attention. Agents, attorneys, and inspectors have fuller calendars in high season. In the green months your search moves faster.

Third, you experience normal life. Low season is what year-round living in Playas del Coco actually feels like, and that is the test that matters if you are thinking about moving here. On the paperwork side, tourist entry stamps now allow stays of up to 180 days for many nationalities, which makes a long scouting trip easier; we covered the details in our post on Costa Rica's 180-day tourist entry.

So when is the best time to go to Costa Rica?

Our short version, from people who live here:

• Guaranteed sun: December through April, booked well ahead.
• Value and greenery: May through August.
• Whales and turtles: August through October.
• Lowest prices, highest rain odds: September and October (still fine in Guanacaste, plan around afternoons).
• House hunting: green season, for honest viewing conditions and better access to everyone you need.

There is no bad month here, only a wrong match between the month and your expectations. If you tell us what you want from the trip, we can tell you exactly when to come, and we can set you up in one of our vacation rentals in Coco or Ocotal so you can test the season for yourself. Questions about dates, neighborhoods, or availability? Send us a message and we will answer from the ground.

Frequently asked questions

What is the cheapest time to go to Costa Rica?

The green season, May through November, brings the lowest prices on rentals, hotels, and tours, with September and October usually the deepest discounts because they are the rainiest months on the Pacific side. May, June, and November often hit a sweet spot: low-season rates with better weather odds, especially in dry Guanacaste.

Does it rain all day during Costa Rica's green season?

Usually not. The typical Pacific-coast pattern is a sunny morning, clouds after midday, and a heavy shower in the late afternoon or evening. Full washout days are uncommon outside September and October. Locals simply plan beach time and tours for the morning, and Guanacaste receives less rain than the rest of the country.

What is the driest part of Costa Rica?

Guanacaste, the northwest Pacific province that includes Playas del Coco, Ocotal, and Tamarindo, is the driest region in the country. Its dry season runs roughly December through April, and even during the rainy months it sees less rainfall than the southern Pacific or the Caribbean coast, which follows a different weather calendar entirely.
