Are you traveling to Costa Rica soon? To plan your holiday, you should know the weather and climate in the country and the best time to visit Costa Rica.
This guide helps you to know which activities you can do in which month and in which region you should book your hotel.
It is fascinating to know that when one side of Costa Rica is drenched in the rain, another side is basking in the sunshine.
This leaves you with choices of activities to book and provinces to discover whichever month you decide to go – with proper planning, of course.
In this article, we aim to understand the weather and, in the process, establish the best time to visit Costa Rica.
Dry Season vs Green Season
There are only two seasons in Costa Rica. The dry season in the country means the wind is warm, and the rainforests are thirsty. The season runs from December to April.
On the other hand, the green season means its wettest months – May to November. This signifies day-long rain showers, a thriving marine ecosystem, and big swells. Costa Rica’s rainforests are also at their greenest.
Costa Rica weather in January
Climate: You will feel that the dry season is coming to Costa Rica.
Temperature: The average maximum temperature is 31 degrees Centigrade, while the lowest temperature is around 21 degrees Centigrade.
January is the best time to visit Costa Rica – and everyone seems to know it. After the holidays, prices start going down, so tourist places get more crowded. Adding to that, the dry season is in full effect, making tours more pleasant.
Specifically, you will find the best weather in Costa Rica in January within the provinces of Guanacaste, Jaco, and Manuel Antonio. These places, due to their good location, receive a lot of sunlight and only light rain.
January is a good month to go hiking in the mountains. If you plan on surfing, head to the Caribbean region, where the season is still green.

The Caribbean is an exception, with occasional rains giving relief to the region. In general, much of Costa Rica’s average weather conditions do not apply to the Caribbean.
Birdwatching and wildlife tours are at their prime as many animals come out of their habitats to bask in the weather and find ways to battle humidity.

Temperature: Average high temperature is 32 degrees Centigrade, while the low temperature is 23 degrees Centigrade.

Be ready for unpredictable weather, though. Plan your tours accordingly and be ready for some plan alterations should the weather change.
It’s the Pacific region’s turn to have good surfing spots. Snorkeling and diving in Costa Rica around May are not recommended as marine animals are harder to spot.

Rain may stop you during nighttime. The August weather in Costa Rica is perfect for rainforest explorations and walking tours. Some days will see no rain; other days, you have to listen to the forecast and hang your coat.
August is starting to get popular amongst travelers because the rates can get pretty low. As many flocks to Costa Rica in the middle of the year to avoid the crowd during holidays, the tours get packed as if it’s December.

Costa Rica weather in November
Climate: It is the end of the green season, and the weather is highly unpredictable.
Temperature: Average high temperature is 31 degrees Centigrade, while the low temperature is 22 degrees Centigrade.
November is not the time to see Costa Rica’s wildlife, nor is it the time to dive and snorkel. Although the humpback whales are in the Pacific the whole time, the waters prove to be too rough for a boat ride to commence.
Canopy rides still do push through rain or shine, but extreme water activities like white water rafting can be canceled any minute.
Your best bet for November lies in the Caribbean. It’s time to enjoy its warm weather and soak in natural hot springs. It’s cheaper, it’s less crowded, and it’s comfortably sunny.
Avoid long road trips if you can, as Costa Rica is prone to mud and landslides.

Climate: Dry season starts this month.
Temperature: Average high temperature is 31 degrees Centigrade, while the low temperature is 21 degrees Centigrade.

The Pacific region is thriving; different turtle species are nesting, and the wildlife is coming out. The Caribbean, though, is back from being wet. Whales can be sighted in the area while huge swells for surfing are formed.
