To understand the weather in Costa Rica we begin by looking at it’s geographical position. Located on the northern hemisphere between Nicaragua in the North and Panama in the South, the weather in this neotropical zone is characterized by high temperatures and rain during a great part of the year. The weather in Costa Rica shows little fluctuations, because the small land mass is influenced by the Caribbean Sea in the east and the Pacific Ocean in the west. Compared to other countries with a bigger land surface the weather in Costa Rica is quite stable. The main factor that has an influence on the weather in Costa Rica is the wind. Because of the mountain range in the center of the country that stretches from the north-west to the south-east, with elevations up to 3.800 meters, the Costa Rican weather is influenced by different wind systems. From December till April the weather in Costa Rica is usually dry, with a little rain. The wet season from May till November has more rain, but usually the weather in this period still gives plenty of sun; 5 hours average. The Caribbean coast doesn’t fit in this pattern and has it’s own weather system. There are no extended dry and green periods and the weather in this part of Costa Rica seems to change back and forth in a two month rhythm. The weather in the Central Valley of Costa Rica is more moderate, thanks to it’s elevated location and offers a comfortable straight 25 degrees centigrade average all year round. In 1888 the National Meteorological Institute was founded to record and study the weather in Costa Rica. Nowadays this institute still plays a prominent role in study, education and forecasting the weather in the different region of Costa Rica. Costa Rica is divided in six regions and the weather of Costa Rica is studied and forecasted for each of these regions. The five regions are: North Pacific, Central Pacific, South Pacific, Central Valley, Northern Region and the Caribbean.. Comparing the weather allover Costa Rica, we can conclude that the North Pacific region has the driest and hottest weather of Costa Rica. The Central Valley also has relative dry weather, but the temperature is lower.
