The month of September matches the month of August in terms of being the hottest time of the year for Puerto Plata both on land and also on the water. Additionally, September marks the climatological height of hurricane season. September 10 is traditionally the peak of hurricane season for areas in the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico. After the 10th, the threat of tropical weather begins to slowly decrease until the end of the season on November 30th. Most tropical systems in the month tend to develop off the African coast and track toward the Caribbean islands or develop in the Caribbean itself, so it is a good idea to keep a close eye on weather conditions that can change suddenly.
This month also begins to see a rise in rainfall on the island as well. After several drier months, the average amount of rain for this time of the year climbs to 107mm spread out over 16 days. However, there is still plenty of sunshine with the region getting approximately 7 hours of sunlight per day.
On both land and sea, temperatures remain very warm despite the fact that the days are beginning to get a little shorter with less sunlight than the previous month. Average sea temperatures are still reaching 29°C (84°F) on a daily basis. Average afternoon highs remain warm with temperatures climbing to 33°C (91°F) during the later afternoon hours. Combined with a relative humidity level that never gets below 80 percent, it can feel much hotter thanks to the moisture in the air. Thanks to the moderating effects of nearby water, the overnight lows do not dip too much during this time of the year. Average lows will only fall to 21°C (70°F) making the early morning hours feel very warm.
With rain chances on the increase in the month of September, visitors may want to head inside and visit the Amber Museum. This unique museum houses a collection of valuable Dominican amber that experts say is the most transparent in the world. Guided tours in several languages are offered Monday through Saturday from 9am-6pm.
However, if the weather is nice, visitors may want to take a tour of the "first city" of the new world, Santo Domingo. This tour is perfect for anyone who wants to step back in time and explore the history of the region. Visitors will get to see Columbus' house and lighthouse as well as take a tour of Santa Maria la Menor Cathedral (the first church of the new world). The tour will take most of the day and lunch is not included.
