What’s the weather like in the Dominican Republic in January?
Sitting in the northern Caribbean, the Dominican Republic has a tropical climate with warm weather all year round. You can expect lots of sun if you're going in January. The island of Hispaniola, which the Dominican Republic shares with Haiti, is quite mountainous, and has quite a big impact on the weather. You'll be drier if you're staying in the south or west because of north easterly winds. On the north coast, the wet season’s from November to January, while it’s May to November for the rest of the island.
Capital Santo Domingo on the south coast has an average high of 29ºC in January. This only cools to 19ºC at night, so you'll still be nice and warm in the evenings and you won’t need to pack many heavy clothes. The sea temperature is 27ºC, while humidity’s high. There’s 63mm of rain over 14 days, and you can expect 11 hours of daylight with eight hours of sunshine each day. UV levels will be very high so don't forget your sun cream. Sunset’s around 6.20pm for much of the month.
