Tropical Climate and its impact on Weather in the Dominican Republic
The weather in the Dominican Republic is the result of the climatic zone in which it is situated i.e. the tropical zone. The climate of the Dominican Republic is described as a “tropical maritime climate” as its weather conditions are influenced by its proximity to the equator and the fact that it is completely surrounded by the sea. The island, therefore, experiences high annual rainfall, temperatures, and humidity all year round with variations on a local scale caused by its topography. For this reason, some persons refer to the Dominican Republic as a place of “endless summer”.
Precipitation in the Dominican Republic is limited to rain due to its location in the tropics and on rare occasions some regions experience hail and even frost on mountain peaks where temperatures fall below 0ºC. The island’s rainy season is between the months of May and November with May typically being the wettest month and March the driest. Rainfall is much higher in the northern regions between the months of October and April and is as low as 640mm in the South-Western arid regions such as Pedernales and Azua. This trend changes in the months of May to November when southern regions receive a majority of the rainfall. Rainfall events are typically short bursts of showers unless there is some disturbance in the atmosphere. The island’s susceptibility to tropical storms and hurricanes owing to its location in the Caribbean also causes an increase in annual rainfall. Warm, sunny conditions are experienced all year round with variations caused by atmospheric instability. Cloud cover is also minimal in the southwest and increases towards the urban areas and forested mountain regions.
Annual temperatures range from as high as 40ºC in the desert regions of the South-West to as low as 16ºC in the colder mountainous regions and even below freezing point to produce frost on mountain peaks. Coastal regions experience highs of 31ºC and lows of around 20ºC depending on the season. The coolest areas of the country are around the Cordillera Central mountain range because of mountain breeze and altitude. However, the average temperature of the Dominican Republic as a whole is 25ºC
Best time to visit the Dominican Republic
The best time to visit the Dominican Republic is therefore between the months of November and April when it is not too rainy and there are more days of sunshine to enjoy.
