The Dominican Republic is a nation on the island of Hispaniola, part of the Greater Antilles archipelago in the Caribbean region. The western third of the island is occupied by the nation of Haiti, making Hispaniola one of two Caribbean islands that are shared by two countries. Both by area and population, the Dominican Republic is the second largest Caribbean nation (after Cuba), with 48,442 square kilometres (18,704 sq mi) and an estimated 10 million people.
The climate of the Dominican Republic is mostly tropical. The annual average temperature is 25 °C (77 °F). At higher elevations, the temperature averages 18 °C (64.4 °F) while near sea level the average temperature is 28 °C (82.4 °F). Low temperatures of 0 °C (32 °F) are possible in the mountains while high temperatures of 40 °C (104 °F) are possible in protected valleys. January and February are the coolest months of the year, while August is the hottest month. Some snowflakes can fall in rare occasions on the top of the Pico Duarte.
The wet season along the northern coast lasts from November through January. Elsewhere, the wet season stretches from May through November, with May being the wettest month. Average annual rainfall is 1,500 millimetres (59.1 in) countrywide, with individual locations in the Valle de Neiba seeing averages as low as 350 millimetres (13.8 in) while the Cordillera Oriental averages 2,740 millimetres (107.9 in). The driest part of the country lies in the west.
The Dominican peso (DOP, or RD$) is the national currency, although United States dollars (USD) and euros (EUR) are also accepted at most tourist sites. The dollar is implicated in almost all commercial transactions of the Dominican Republic.
Tourism is fueling the Dominican Republic's economic growth. With the construction of projects like Cap Cana, San Souci Port in Santo Domingo, and Moon Palace Resort in Punta Cana, the Dominican Republic expects increased tourism activity in the upcoming year. Ecotourism has been a topic increasingly important in the nation, with towns like Jarabacoa and neighboring Constanza, and locations like the Pico Duarte, Bahia de Las Aguilas and others becoming more significant in efforts to increase direct benefits from tourism.
