Dominican Republic: Climate

The Dominican Republic is hot and tropical, with little seasonal variation in temperatures, which average about 77°F (25°C). Seasons can, however, be determined by rainfall, with October to April being the rainy season on the north coast, while May to November is the wettest month in the south of the country. The driest area is the west. Cooler temperatures and less humidity is generally experienced between November and April, while the mountainous interior is always cooler than the rest of the country. Hurricanes occur on average once every two years on the island, most striking the south of the country and most happening in August and September. The busiest time of year to visit the Dominican Republic is between December and April when North Americans take a tropical break from their winters, and from June to September, which coincides with European summer holidays.
