Despite this decline, rainfall remains relatively substantial, ranging from 70mm (2.76") to 180mm (7.09") across different regions of the country. The reduction in precipitation coupled with an increase in temperature indicates the slow shift towards the dry season.

The lower precipitation levels in September, compared to July and August, lead to fewer overcast days, with more sun exposure throughout the day. This increases the intensity of the heat during the daytime, despite the relatively cooler temperatures in comparison to the hot season.

Looking ahead to October, the rainy season ends completely, and the dry season takes over. Temperatures continue to rise gradually as the country transitions into this dry period. Therefore, September can be considered a transition month between the wet and dry seasons, characterized by decreasing rainfall and moderately rising temperatures.
