Weather in the North Coast of the Dominican Republic is usually sunny year round, and until recent years the rainy season was between April and June. Due to climate changes worldwide, now it is possible to have a week of rain and then several weeks not raining; or the other way around. In most cases the weather in DR is considered tropical and pleasant. Winters bring a cool breeze that gets chilly at night, though people rarely use any extra clothing.
