What's unique about this month, besides the heavy rains, is the gradual decline in temperature as the year progresses. Taking a numerical snapshot, record rain showers amounting to 328mm (12.91"), combined with the temperature domain from a cooler 23.6°C (74.5°F) to 31.4°C (88.5°F), cement September's station as wet and moderately warm.

Guard: Heat exhaustion and heat cramps are foreseeable. Prolonged effort may bring about heatstroke.
Heat index's context suggests values are appropriate for shady areas and slight breezes. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.
