The rainy season in Costa Rica typically runs from May to November, with the heaviest rainfall occurring in September and October. The weather in Costa Rica can vary depending on the region, so it is best to check the forecast for the specific area you will be visiting. Costa Rica is a tropical country, so it is generally warm and humid throughout the year, but the rainy season can bring heavy downpours and thunderstorms. The rainy season is also known as the "green season" because the increased rainfall helps to nourish the plants and vegetation, making the landscape particularly lush and green.
