Costa Rica is a tropical country and like most countries in the tropics has two seasons - a wet and a dry season.
The dry season is from December to April and the rainy season is from May to November.
Because Costa Rica is so diverse and has micro climates, this isn't always exactly correct.
In the Northern Lowlands, for example, where the Arenal Volcano is situated, the rainy season is from December to March and the dry season is from April to November.
Costa Rica weather is as diverse as the country, which is close to the equator and thus has no winter.
Because of this, the length of the day is the same all year round - the sun rises around 5am and sets at 6pm with around 12 hours of sunshine each day.
That's pretty perfect if you like it warm and don't miss skiing and snowboarding! The reason that the weather in Costa Rica is so varied is because of the difference in elevation.
For example, the Guancaste area is in the lowlands and the climate is dry, whereas Montverde is in the highlands and so is misty and foggy throughout the year.
The best weather is enjoyed in the Central Valley where the capital San Jose is located - here you can enjoy an average temperature of 72 degrees Fahrenheit with a cool breeze from the ocean.
At sea level, it is warmer - around 79 degrees Fahrenheit and the days are hot and the evenings are sultry.
On the Caribbean coast, for example, the trade winds keep the weather hot and humid with lots of rain and no read dry season.
Also, we shouldn't forget the many rainforests where of course, it can be quite misty and sultry.
If you're looking for a home in Costa Rica, many Americans buy elevated plots of land where they can see the ocean but because it's higher up, there are few insects to worry about.
Costa Rica is a wonderful place to visit or to live.
The overall climate is tropical and Costa Rica weather is pretty warm all year round with lots of sunshine in most of the country.
