A clear transition from the rainy season to the dry season is indicated in September. It begins with a steep decline in rainfall from its August peak, with precipitation amounts reducing to 123mm (4.84"). Gradually cooler temperatures and receding rainfall mark the onset of the drier months. However, the amount of daylight and the duration of sunshine remain relatively consistent. The wind speed reduces significantly in this month, making the weather considerably calmer compared to the previous rain-dominant months.

Temperature

September's arrival brings an average high-temperature of a tropical 30.8°C (87.4°F), demonstrating subtle variation from the preceding month. The average low-temperature during September nights is an agreeable 22°C (71.6°F).

Heat index

In September, the average heat index is estimated at a blisteringly hot 41°C (105.8°F). Incorporate additional safety actions, heat cramps and heat exhaustion are possible. Long-term activity may induce heatstroke.
Heat index specifics point out values are for conditions of shade and a slight breeze. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Guard against overexposure. Protection from sun-induced harm is essential. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. Sunglasses providing both UVA and UVB protection are non-negotiable on sunlit days.
