These temperatures are in Celsius (average high is 870 F, average low is 73 0F)
Cool season
The so-called "cool" season is from November to April, with what is considered pleasantly warm weather, relatively low humidity and low precipitation. On the coast, i.e. near the beaches, the temperature hovers fairly constantly around 29 0C (84 0F) during the day and drops to around a comfortable 20 0C (68 0F) at night.
Hot season
The more "hot" season is roughly from May to October. Then, the average temperature rises to 31 0C (87 0F) during the daytime and drops to about 22 0C (72 0F) at night. However, with the accompanying high humidity that is more common during this season, it usually feels much hotter. It does rain a bit more often during this season, especially from May to August, but usually this turns out to be no more than a 30 minute tropical (sometimes heavy) shower.

Differences
The differences between the two seasons is not always consistent; sometimes regardless of the season there are periods of weeks without any rain at all, except occasionally during the night. Visitors coming to the Domican Republic, practically any time of the year can expect to be treated with extended periods of blue sunny skies, ideal weather for getting a nice tan. It should also be mentioned that weather varies a lot from one year to the next, being influenced by phenomena such as "El Nino" and "La Nina" among others.
Hurricanes
The Caribbean hurricane season lasts from June 1 to November 30. August and September are the months when most hurricanes have hit. The greatest threat to the Dominican Republic comes from hurricanes. The major resorts have become adept at getting back on their feet quickly after a hurricane, as evidenced by the quick rebound from the devastation of Hurricane Georges (1998).
Still, if a hurricane hits the country before your trip, you might want to call ahead and make sure your room is still standing...
