September weather forecast
Dominican Republic

In the Dominican Republic, September signifies the end of summer and the transition into autumn. Yet, the tropical climate maintains high temperatures and significant rainfall. The average temperatures usually hover between 22°C (71.6°F) and 33°C (91.4°F), indicating a slight decrease from the peak summer month of August. However, this transition does not bring about a major relief from the heat.

Despite the slight drop in temperature, the higher regions such as the Cordillera Central range continue to offer a cooler alternative to the heat of the lower regions. These regions, however, also start to experience a decrease in temperature as autumn approaches.

September brings considerable rainfall, maintaining the pattern observed in the previous months. Northern and southern regions alike, including cities like Puerto Plata and Santo Domingo, experience frequent showers, often in the afternoons or evenings. The downpours continue to contribute to high humidity levels, which make the weather feel hotter than it is.

Compared to August, September sees a subtle reduction in temperature but a continued trend of substantial rainfall. Despite the heat and rain, early mornings and late evenings still present the most comfortable periods for outdoor activities.

Wind conditions in September maintain the same pattern as the previous months, with the northeast trade winds keeping wind speeds typically below 32.2km/h (20mph). Importantly, the frequency of tropical storms and hurricanes reaches its peak in September, emphasizing the increased vulnerability of the country during this period.
