The weather in Punta Cana is very mild all year-round, with the temperatures averaging around 25°C (77°F). There is a very slight difference in the temperature from season to season. Travellers visiting Punta Cana at any time of the year may almost count on extended periods of sunshine and blue skies – an ideal weather for relaxation, water sports and getting a nice suntan.
During the “cool” season, from November to April, the weather in Punta Cana is pleasantly warm, with relatively low levels of humidity and low precipitation. Temperatures along the coast are constant around 29°C (84°F) during the day and drop to a comfortable 20°C (68°F) at night.
During the “hot” season, which runs roughly from May to October, the average temperature rises to 31°C (87°F) during the daytime and drops to about 22°C (72°F) at night. However, due to the high level of humidity during this season, the temperature feels much hotter than registered by the thermometer. Occasional quick rain showers or minor tropical storms bring some respite from the heat during this season.
It is recommended that visitors bring light clothing, preferably made of cotton or other natural materials. Punta Cana, along with most tropical destinations, does have a “mosquito problem”, particularly in the rainy season. The mosquitoes usually appear after dark, and visitors are advised to wear long sleeved shirts and long pants or skirts and to use insect repellent before venturing outside.
Despite such minimal difference between the temperatures in summer and winter, the climate tends to vary a lot from year to year due to the influence of the weather phenomena known as “El Niño” and “La Niña” among others. The greatest threat to the Dominican Republic comes from hurricanes. The Caribbean hurricane season lasts from June 1 to November 30. August and September usually experience the most hurricanes.
