September remains excruciatingly warm and humid in Bayahibe. Daytime highs of 31°C can create uncomfortable conditions, while evening temperatures only drop to around 22°C.
Mosquitoes are also a problem in the evenings, so be sure to bring mosquito repellent and wear long sleeved tops when out and about at night.
Clothing should be made of light, breathable fabrics such as cotton or linen to stop you becoming too hot.
If you are heading to the beach during the day, you should take steps to avoid sunburn or sunstroke. Drinking plenty of liquids is essential during hot weather and, as Bayahibe is especially humid, you will be losing a lot of moisture through sweating. Always wear sunscreen with an appropriate SPF.
The beautiful beaches in the area usually have umbrellas available to provide shade during especially hot parts of the day.
September is the height of hurricane season in the Dominican Republic, so you may experience one during your stay. Please be vigilant of weather warnings at your resort.
Rain showers are common during the day but do not tend to last very long and will probably be a welcome break from the intense heat!
Away from the beaches there is still plenty to see.
The artist's village at Altos de Chavon was built to resemble a European renaissance village, but was actually built in the 1970s by a film set designer! You can take a stroll round the cobbled streets and browse the numerous galleries and studios before having a drink in one of the many bars and cafes.
There is also a 5000-seat amphitheatre where performances by big names are still regularly held.
