LANDSCAPE AND CLIMATE
The second largest nation in the Caribbean, the Dominican Republic is located on the island of Hispaniola, which is part of a group of islands called the Greater Antilles. The Dominican Republic occupies the eastern two-thirds of the island and Haiti occupies the western portion. To the north is the Atlantic Ocean and to the south is the Caribbean Sea. The Dominican Republic's island neighbours include Cuba and Jamaica to the west and Puerto Rico to the east.
The country is crossed by four parallel mountain ranges running northwest to southeast, with fertile valleys in between. The largest is the Cordillera Central, extending from northwest of Santo Domingo into Haiti. Its peak, Pico Duarte, is 3,175 metres high. It is the highest point in the Caribbean and is sometimes covered with snow and frost during the winter. Along the north coast is the Cordillera Septentrional. South of the Cordillera Central are the Sierra de Neiba and the Sierra de Bahoruco ranges. Between the Sierra de Neiba and the Sierra de Bahoruco is Lake Enriquillo, the largest natural lake in the country, with the lowest elevation in the Caribbean islands. This is also the only salt water lake in the world inhabited by crocodiles.
  Did you know?
The northern coast of the rocky shelf on which Hispaniola sits provides an excellent breeding ground for humpback whales. During the first few months of the year, humpback whales can be seen off the northern coast of the Dominican Republic near Puerto Plata.
More than a third of the coast is bordered by golden sandy beaches, especially the northern Atlantic coast. Most of the country's tourist hotels and resorts are concentrated in this area. Between the Cordillera Central and the Cordillera Septentrional lies a fertile stretch called the Cibao Valley. This area, as well as the lowlands in the southeastern region, are the most fertile areas of the country.

 The Dominican Republic is geographically diverse for its size. Its vegetation zones range from evergreen forest in the highlands to the desert-like environment around Lake Enriquillo. 

The island enjoys a tropical maritime climate year-round. There are almost no seasonal differences in temperature. Most of the temperature differences are caused by variations in altitude. The average temperature is about 20°C, although at low altitudes such as Lake Enriquillo, the temperature can rise to 40°C. Humidity is about 70% most of the time. 

The rainy season is from May to November, with rainfall heaviest in the northern regions and lighter in the southwest. The hurricane season lasts from June to November, with August and September being the peak months. In September 1998, Hurricane George caused major damage and many deaths in the southeastern region.
