The Dominican Republic enjoys a year round privileged tropical maritime climate. Its 17° 36' — 19° 58' minutes north latitude places the DR at the border of the tropical zone. Sea breezes refresh the insular territory (390 x 265 kms), evening out temperatures to average 23°C in the early mornings to 32°C at noon time year round.

The lowest temperatures occur in the mountain areas near Constanza, where temperatures have dropped to 0°C, and record highs have been registered at the frontier with Haiti, 39°C in the summer. It is more likely to rain in May through November.

The hurricane season lasts from June through November, with August-September being the peak months. The last major hurricanes to hit the Dominican Republic were Georges (September 1998) and David (August 1979).
