April: April might be in the dry season but it can still rain towards the end of the month – it starts getting humid in April.

May: In May, you might find it rains off and on sporadically. Some days there will be more rain than others. It could rain really hard for about 10 minutes and then be hot and cloudless for the rest of the afternoon!

June: June is similar to May but you might see a bit more rain. It tends to rain more on the Caribbean coast in June.

July: The locals call July the “little summer”. Somewhere around the middle of July, the weather gets drier with clear skies and not a lot of humidity. It can still rain in July though in the rainforest areas.

August: August is usually typical of rainy days with sunny mornings and cloudy afternoons. Rain can pick up in the afternoons and nights towards the end of the month.

September: This is the time when the rainiest months start.There will be more clouds and rainy afternoons and nights. The Caribbean becomes drier now. September and October in Costa Rica also tend to be the coldest months in Costa Rica.

October: This is the driest month for the Caribbean side only. In the rest of the country, you can expect sudden rainstorms during the day and continue raining into the night. On the Pacific side, you can get dry weather, but the mornings will be cloudy and in the afternoon it will start raining.

November: Still expect a good amount of rain in November throughout the country, although the weather starts transitioning to dry season. Still, you might see rain in the afternoons and nights with the coast having hard rain at night.

December: The beginning of December is very nice as the weather is becoming drier. But still, it can rain at the beginning of December. By the end of the month, you won’t really see a lot of rain. But you can expect wind throughout the Central Valley and North Pacific coast.

The best things to do in the rainy times because when life gives you rainy times, you play in the puddles

White water rafting and tubing are very popular and a whole lot of fun for people in the rainy season. But September through to November, it can get a bit hectic and tour companies will even cancel tours if the rivers are too full and looking a bit dangerous.

Coffee tours: The coffee harvesting season starts around September through to December/January. This gives you the chance to see the whole picking, separating, and processing procedure.

Museums: On a rainy afternoon in San Jose, you can visit the indoor museums and also the Central Market.

The rainy season in Costa Rica is also known as the “green season”

The rainy season is often characterized by sunny mornings and daily rain showers later in the afternoon. Often the weather even becomes a bit cooler even though the sun is shining.

The rainy season starts in May, building up to around September and October when Costa Rica is probably at its rainiest. The dry season experiences hot, dry weather. Around mid-July, there is a little mini type of summer break – called the “El veranillo de san Juan”.

The winter seems to have a break and you experience a bit of gorgeous summer-like weather then. Some people even like to travel to Costa Rica at this time to experience this perfect weather time in July.

Even though the rainy season does start in May, the rainy weather doesn’t really start until the end of the month. Thanksgiving week is quite popular for travel to Costa Rica for those who want to avoid the rain, and also keep prices a bit lower.

But to be honest, even when the weather is “freezing” as the Ticos will call it, and it is raining as well, still, the weather doesn’t get much lower than 60° F, which means a fleece jacket might be the warmest clothing you will need, and you might even be too hot.
