The Dominican Republic is located almost due east of Haiti and borders the Atlantic Ocean in the north and the Caribbean in the south and east. With Haiti the Dom Rep has a national border with a length of around 360 km.

The state covers a total area of 48,700 km². Thereof:

For detailed explanations of ebb and flow, see Tides, Ebb and Flow.


The world’s highest tidal range can be found in the Bay of Fundy in Canada, where it is up to 16 m, and at spring tide even over 20 m. The Bay of Fundy is located on the Atlantic between the Canadian provinces of New Brunswick and Nova Scotia, which is called Nova Scotia in German and whose capital is Halifax.

On the German North Sea coast it varies between 1 m and 3 m. In the western Baltic Sea, on the other hand, the tidal range is only 0.3 m, while it is barely noticeable in the eastern Baltic Sea.

Longitude and latitude

The Dominican Republic extends over the following geographical latitude (abbreviation Δφ) and geographical longitude (abbreviation Δλ):

Δφ = from around 18 ° to 20 ° north latitude Δλ = from around 068 ° to 072 ° west longitude

You can find detailed information on this subject under Longitude and Latitude.


For the Dominican Republic, the following value applies to Central European Time (CET), i.e. the time without summer time. A minus sign means that it is earlier there and a plus sign that it is later than after CET:

Δt (CET) = – 6 h

Further and detailed explanations of the time can be found under Time zones, time.

The highest point of the sun in Santo Domingo

Santo Domingo is located at a north latitude of around φ = 18.5 ° and thus in the tropics.

If the declination δ of the sun has the value of 18 ° 30 ‘N, and so the image point of the sun is exactly above the city or island, the sun is perpendicular there. This happens exactly twice a year, roughly 19 days before June 21st and 19 days after June 21st (for details see under Sun position).


If the image point of the sun and thus the declination is north of the latitude of Santo Domingo, the sun is not in the south at noon, as in our latitudes, but in the north. In this case, the sun moves from east to north to west, where, like us, it sets.

The border in the east and north form the following islands or archipelagos starting from Venezuela in a semi-circle to the “actual” Atlantic: Trinidad and Tabago, Grenada, St. Lucia, Dominica, British Virgin Islands, Puerto Rico, Haiti and Cuba.

The deepest point in the Caribbean is the Cayman Rift between Jamaica and the Cayman Islands with a depth of 7,680 m. Together with the Gulf of Mexico, the Caribbean forms the “American Mediterranean”. A detailed presentation of the Caribbean here >>>

The Atlantic Ocean

The Atlantic Ocean (Atlantic) is the second largest ocean in the world after the Pacific with an area of around 106 million km². It separates America from Europe and Africa. At 9,220 m, it has its deepest point in the Milwaukee Deep – part of the Puerto Rico Trench. Its salt content is on average 3.54% (g/ l). Its water volume is approximately 355 million km³.

Coming from the Gulf of Mexico, the Gulf Stream crosses the Atlantic to the coast of Norway and is largely responsible for the climate in Western and Northern Europe.
