The climate of Dominican Republic
Most parts of the Dominican Republic have a tropical savannah climate. Type Aw according to the Köppen-Geiger climate classification. Because of the rainfall all year round the north eastern part of the country has a tropical rainforest climate (type Af). Temperatures in these areas are between 28-33 degrees Celsius all year round. During the night temperatures hardly ever drop below 20 degrees Celsius with the exception of the higher regions and the interior. Because of the large amounts of precipitation the south western tip of the Dominican Republic has a warm steppe climate (type Bsh). The Dominican Republic is one of the most popular sun destinations outside Europe. This is because of the excellent weather, the many beautiful hotels and the beautiful beaches. The tropical white beaches of Punta Cana and Bavaro are without a doubt among the most beautiful in the Caribbean and even in the world. Many photographs of white palm beaches with an azure blue sea and a bright deep blue sky have been taken here. The frequent cloudy skies make for a nice contrast with the blue skies. During the winter these photographs make you long for a holiday.

Frost
The Dominican Republic is the only country in the Caribbean where subzero temperatures occur. According to the latest records this is the highest mountain of the Caribbean (3098 meters). Subzero temperatures are not uncommon here. During the winter months the frost line may drop several hundreds of meters and even the inhabited areas get frost and ice. During the winter of 2006/2007 the forests surrounding the mountain city of Constanza (1220 meters) where covered with a small layer of ice. This phenomenon attracted many of the islands inhabitants.

Summer in the Dominican Republic
The summer months in the Dominican Republic are warm and moist and relatively sunny. Temperatures at sea level are around 31-32 degrees Celsius on the entire island. The island gets about 8 hours of sunshine per day. During the months of July and August Punta Cana gets 9 hours of sunshine per day. During these months it frequently happens that the inland is cloudy but Punta Cana remains sunny. However, rainfall is not uncommon. Most of the regions in the Dominican Republic get more rain during the summer months than during the winter months. The south coast and the higher regions have a real wet season during the summer. A large amount of rain can fall within a short period of time, especially in the mountains. Whoever goes into the mountains either by mountain bike or on foot needs to bear in mind that the weather can change very rapidly. In the morning it may be sunny, but in the course of the day torrential downpours may develop which prevent you from seeing anything at all.

Hurricanes
The Dominican Republic is situated in a region with frequent hurricane activity. From June till the end of November hurricanes may occur. They usually come from the east. Just like most of the other islands in this region the Dominican Republic may get hit by a hurricane. Chances of hurricanes shouldn’t be exaggerated because this phenomenon doesn’t happen every year and when it does it usually happens in a small part of the country. When there is a serious threat of a hurricane, the authorities will take precautions in time. In the worst case scenario some parts may get evacuated or you can’t travel for 1 or 2 days. Casualties or wounded hardly ever occur among tourists because the hotels can withstand fierce storms and hurricanes. Chances of a tropical depression are higher. This is often accompanied by a lot of rainfall and fierce winds in a short amount of time. However, this type of weather is usually short lived. Usually you can enjoy the beaches again after 1 or 2 days.

Winter
Winters in the Dominican Republic are not much colder than the summer. During the day temperatures at sea level are still around 30 degrees Celsius. This makes the Dominican Republic an excellent winter sun destination. Whoever goes on their honeymoon to the Dominican Republic and wants to be assured of sunshine best travels to either the east coast (Punta Cana, Bavaro) or the south coast (Santo Domingo, Boca Chica). These places are much drier during the winter than during the summer.

UV-index
The UV-index in the Dominican Republic is high. A large part of the year the highest figure is reached (UV-index 11). Going into the sunshine unprotected is not sensible; unless it is for a very short period of time (10-15 minutes). All the year round the use of sunscreen with a high protective factor (with a minimum of 30) can be recommended, even for those who don’t get sunburn that quickly. During the winter these figures are not much lower. The months of November, December, January, February and October are a little milder for your skin. Bear in mind that the UV-index can still be compared to the index figures during the summer in Spain.

Precipitation
The tropical climate in the Dominican Republic doesn’t only bring much warmth and sunshine but also rain and relatively high humidity figures. Depending on the region and seasonal influences reasonable amounts of rain fall. In the north eastern part in the regions surrounding Samana and Las Terrenas quite a lot of precipitation can be expected all year round. The National Park of Los Haitises benefits from the large quantities of rain. Not only do big differences occur per region or per month, it is not always the same every year either and it is possible that certain regions show large deviations compared to the long term records. If you are lucky you get more sunshine, if you are unlucky you get more rain than usual.

Climate figures are very useful but don’t present a general impression of the climate and the eventual weather circumstances within a certain period. The figures don’t always reflect the chance of wintry weather, extreme heat or hurricanes. That is why we monthly offer useful extra climate information.
