The best time to visit Costa Rica is January after the holiday peak season tourist crowds head home. The rains end in December but the forests remain lush into the new year while dry sunny weather prevails on the beaches.
It’s one of the best times for wildlife when tropical species like monkeys and sloths are joined by migrant birds from the north, humpback whales giving birth in the warm waters, and sea turtles nesting on shore.
Another excellent answer to the question “when is the best time to go to Costa Rica?” would be July and August when there’s a bit more rain but even fewer visitors and lower prices. In fact there’s no bad time to go. It really depends on what your travel goals and priorities are.

When is the Best Weather?
The best weather depends on where as well as when. There are a number of distinct microclimates in Costa Rica and it can be flooding in one zone but bone dry in another.
We’ve visited at every time of year and while there are advantages to the high dry season (see suggested itineraries) we often prefer the low rainy season (referred to by the tourism board as the “Green Season”).
As you can see by comparing the weather maps there are a few places where it would be ill advised to visit at specific times because of the weather (the Osa/Southern Pacific in October for example) and some undiscovered and uncrowded times with gorgeous weather (the Caribbean in October).
Other comparisons and suggested alternatives are noted in the summary of each month linked in the drop down menu.
Don’t forget while browsing all the weather and climate data that one of the reasons you’re visiting Costa Rica is because it’s covered in amazing rain forests, and surprise, surprise – it rains in the rainforest.
Crowds, Costs and Other Factors?
There used to be distinct high and low travel seasons in Costa Rica but the secret is out. July and August are as popular as December. Discounts have shrunk or even disappeared.
There are still cost differences depending on dates. For example, Christmas and Easter peak weeks are nearly twice as expensive as the average and the shoulder months (May/June and Sept./Oct./Nov.) are uncrowded with price breaks available.
If you’re going to travel over Christmas or Easter you should book about a year in advance for the best selection and some places are filled even further in advance. Shifting your travel by a few days away from the holidays can make a huge difference.

NOAA and other agencies are predicting a good chance of an El Niño Weather pattern building in October and November of 2019 and continuing into 2019. Typically El Niño decreases rains on the Pacific side and makes the Caribbean a bit wetter. Something to keep in mind when looking at the rainfall maps.
Ash from intermittent eruptions of Turrialba volcano have occasionally disrupted operations at San Jose (SJO) airport since 2015 into mid 2018 and are expected to continue sporadically – see Choosing an Airport for more info.

The New Year is one of the most popular holidays for Ticos, Europeans and snow birds from the U.S. to head to the beach. It’s very sunny, warm, crowded and expensive. Wait a couple of days and you’ll discover one of Costa Rica’s best kept travel secrets. Around January 5th the prices drop, the crowds disappear and there are four to six weeks of perfect weather. The rainy season just ended so the forests are still green and lush and the rafting rivers and canyoneering waterfalls still have plenty of flow. – BEST TIME
The number of travelers starts to pick up in February. The dry season is well established and the trees of the tropical dry forests on the Pacific side in Guanacaste and Nicoya are dropping their leaves. The rivers in the central mountains still have plenty of water and the Caribbean side is in it’s normal pattern of afternoon showers. February is a great time to visit the Osa Peninsula and it’s the beginning of the nesting season for the Quetzales in the cloud forests. – BEST TIME
These two months get lumped together because they’re very similar. It’s busy because of north American spring breaks and mobbed the week of Easter when the Costa Ricans all go on vacation at once. The southern, central and eastern parts of the country are still green but some river levels drop too low for rafting. The northwest is bone dry, the trees are bare and the rivers are reduced to trickles there. – BETTER TIME
The transition into the rainy season is gradual with showers starting in May and picking up in June. The dry season dust is settling and the rivers are filling up. The wildlife breathes a sigh of relief as things cool down a little and the tourists all but disappear. Sea Turtle nesting is in full swing on many of the beaches for many species. – GOOD TIME
This is the best off-peak time to visit Costa Rica. Costa Rica is a great escape from the snow but it’s also a fantastic summer beach destination and the rains typically let up a bit this time of year. Inland the rivers are at their best for rafting and waterfall rappelling. The Sea Turtles are still around and the Antarctic Humpback whale pod is taking up residence in the warm waters of the Golfo Dulce. – BEST TIME
September & October
This would be a good choice if you want the whole Pacific side and central mountains to yourself. These are the rainiest two months in those zones and the grey weather is accompanied by the biggest discounts of the year. The Caribbean side on the other hand is enjoying its driest weather. – BEST TIME FOR THE CARIBBEAN
November & December
The first six weeks are something of a gamble for weather and could easily be the wettest of the year or relatively dry anywhere in Costa Rica. Discounts are available and reservations are easy to come by. By the last two weeks of the year it usually drying out in the Pacific northwest but come rain or shine it’s the peak season with the highest prices and biggest crowds everywhere in the country. – GOOD TIME
