Although Costa Rica is a small country in terms of area, there is a lot going on here in terms of weather in Costa Rica. With a climate that is diverse and varied, Costa Rica can be divided into several climatic zones, each of which are distinct and individual. Though generally classified as a tropical country because of its close proximity to the equator, Costa Rica has no real winter period, and the sun shines here throughout the year. In general the weather can be classified as a dry or high season and a wet or green season. With over 12 hours of sunshine a day, the sun rises at about 5:45 am and sets at about 5:45 pm consistently throughout the year.
The main reason for the diversity in Costa Rica lies in the fact that Costa Rica has an ocean and a sea relatively close to each other, the Pacific Ocean and the Caribbean Sea. Of course elevation does also take part in the diversity of weather as well. For example Guanacaste which is next to the Pacific Ocean has a dry climate where there are many tropical dry forests, while Tortuguero which is on the Caribbean Ocean that is only about 130 miles or 210 km away (as the crow flies) has very humid and wet weather with rain throughout much of the year.
The Central Valley with San Jose enjoys the best climate in the country as the weather here has an average of 22 degrees Celsius or 72 degrees Fahrenheit and is tempered with a cool coastal breeze. In the highlands the temperature averages 13 degree Celsius, while in the lowlands or at sea level the temperature stays at around 26 degrees Celsius or 79 degrees Fahrenheit, with hot days and sultry evenings.
