What’s the weather like in the Dominican Republic in September?

The Dominican Republic shares the island of Hispaniola with Haiti in the northern Caribbean. The island’s mountainous so the weather’s quite diverse. You’ll have less rain in the south and west as high mountains will shelter you from north easterly winds. The north coast’s wet season runs from November to January, while it’s from May to November for the rest of the island. You’ll still get plenty of sun in September as it usually rains in short and heavy bursts which often come in the evening and quickly clear.


The average high in capital Santo Domingo is 32ºC in September, and things stay nice and warm in the evenings at 22ºC. The sea temperature’s a warm 29ºC, which is perfect for swimming, while humidity’s very high. There’s 174mm of rain over 14 days, but you can still expect 12 hours of daylight with eight hours of sunshine each day. UV levels will be extremely high so take plenty of sun cream. The sun goes down just before 7pm at the start of the month.
