The Dominican Republic is known for its beautiful weather and nearly year-round warmth and sunshine; some people refer to the Dominican Republic’s climate as “endless summer.” The climate is tropical maritime, with an average temperature of 77 degrees Fahrenheit.
Most rain falls in the east and north regions, historically with the most accumulation in May. Rainfall is higher from November to February, when it is common for passing morning or evening rain showers, with sunshine during the day.
Evenings are cooler during the months of November to April, as compared to the summer. The mountainous regions on the country’s interior are a higher altitude and have cooler temperatures than the rest of the island. Temperatures may drop below freezing, and frost can be seen on their peaks
Summer in the Dominican Republic is May to October, and is the hottest time of the year. Temperatures range from 87-90 degrees Fahrenheit during the day, with a nighttime low of 72 degrees. The high humidity during the summer raises the heat-index and the temperature can feel even hotter than it really is.
As with all of the Caribbean, the Dominican Republic is affected by hurricane activity. Hurricane season is from August to November, with the most action in August and September. Because of the nearby mountain ranges, the North Coast is protected from dangerous storms. The main affects are epic surf conditions and passing wind and rainstorms.
