There are two main seasons in the Dominican Republic, the cool season which runs from November to April and the rainy season from May to October.  A lot of people and visitors to the island prefer the cool season as the heat is less intense, the humidity is lower and the rainfall is less frequent.  Temperatures are generally around 29oc during the day and will go down to about 19oc at night.

During the rainy season the rainfall can get very heavy, on the good side though the showers are heavy but short lived. Rainfall can wash out roads and make traveling difficult throughout the island. Rain is most frequent from May to Mid June (although for the last two years the rainy season has in fact been very dry).

In rainy season the average temperature is 31oc during the day and 22oc at night.

As you can see there isn’t that much seasonal variation between temperatures, although the summer months seem to get hotter each year and August can be sometimes unbearably hot, however if you are within arms reach of a swimming pool my advise is to do like the hippos do and just wallow around in some cool water!

Hurricane season runs from June to November and the Dominican Republic lies within the hurricane belt.  It is not possible to predict when a storm/hurricane will occur but with today's hurricane warning stations and systems they can certainly be tracked a lot quicker and warnings be given earlier than in years gone by.
