September is not the best month to go to in Trinidad and Tobago. The climate in Arima, Chaguanas and Port Of Spain is bad. It's cold, the sun is not there all the time and you take the risk being faced with rain very regularly.
But it's ultimately better than around the cities of Arima, Chaguanas and Port Of Spain and surrounding areas where the climate is even worse. We really do not recommend you to go to these areas this month.
