Costa Rica Regional Climate Characteristics

Costa Rica is a tropical country with two distinct seasons—dry and wet. However, within these seasons, there is a significant variation between different regions of the Country. The Guanacaste Province on the northwest Pacific Coast is the driest. The Caribbean Coast has unpredictable and generally wetter weather, and the southern Pacific Coast is wet and hot year-round.

The reason for this diversity is the close proximity of the Pacific Ocean and the Caribbean Sea, as well the mountain ranges that separate these two bodies of water. If you travel from one coast of Costa Rica to the other, or from the coast to the mountains, you’ll experience a totally entirely different micro-climate in each of these regions

An interesting observation is that of the geographical position of Costa Rica with respect to hurricanes passing-by in the Caribbean. Costa Rica, while experiencing the side-effects of passing hurricanes, rarely, if ever, experiences a direct hit by one. The position of the Gulf Stream Ocean Current keeps the hurricanes offshore to Costa Rica.
