🇩🇴Dominican Republic

The Dominican Republic occupies the eastern two-thirds of Hispaniola between 17°36′ and 19°56′N in the Greater Antilles, sharing the island with Haiti to the west. Rugged topography is dominated by the Cordillera Central rising to Pico Duarte at 3,098 m—the Caribbean's highest peak—along with the Cordillera Septentrional in the north, the Cordillera Oriental, and the Sierra de Bahoruco in the south.

Major climate regimes range from tropical rainforest Af on the wet northeastern Samaná peninsula and Cordillera Septentrional windward slopes, tropical monsoon Am along the south coast, tropical savanna Aw across the central Cibao Valley and the dry southwest including Pedernales and Barahona, to a small Cwb temperate highland zone above 1,800 m in the Cordillera Central and a hot semi-arid BSh pocket around Lake Enriquillo, the Caribbean's lowest point at 46 m below sea level.

Santo Domingo averages 24°C in January and 28°C in August with 1,400 mm of rainfall split between peaks in May to June and September to November. Santiago de los Caballeros in the Cibao Valley is hotter and drier with around 1,000 mm annually. Puerto Plata on the Atlantic coast receives 1,800 to 2,200 mm. Constanza at 1,200 m enjoys sub-tropical mountain spring weather averaging 16°C, while Pico Duarte at 3,098 m occasionally records frost.

The Dominican Republic lies within the Atlantic hurricane belt and has experienced major hurricane landfalls including Category 5 David (1979), Georges (1998), and Category 1 Fiona (2022), which brought significant flooding. Tropical Storm Olga (2007) produced heavy rainfall, and the Cibao Valley is subject to recurrent flooding. A Caribbean-wide drought occurred from 2015 to 2016, causing water shortages.

The El Niño–Southern Oscillation (ENSO) drives large inter-annual variability in precipitation patterns and hurricane frequency. Sea-level rise and coral bleaching continue to threaten coastal ecosystems, particularly around Punta Cana and the southern coast.
