The climatic conditions in December in the Dominican Republic exhibit unique characteristics shaped by the country’s location in the Caribbean.

The Dominican Republic is situated in the Caribbean Sea, southeast of the Bahamas, and northwest of Puerto Rico. This location exposes the country to various climate influences from both the Atlantic Ocean and the Caribbean Sea. As a result, the Dominican Republic experiences a unique combination of tropical and subtropical climate conditions throughout the year. In December, the country is influenced by the warm ocean currents of the Caribbean Sea, resulting in mild temperatures and relatively low humidity levels.
Warm Ocean Currents Surrounding the Island

This warmth is especially noticeable in beach areas, such as Punta Cana and Bavaro. Additionally, the ocean currents help regulate humidity levels, resulting in relatively low dew points, especially on coastal areas. This results in clear skies and pleasant conditions ideal for activities such as sunbathing and surfing.
