September brings about the beginnings of transition in
Kalabagan. A dip in rainfall—300mm (11.81")—and a slight calming of temperatures start the dial-back from monsoon high. The shorter daylight hours keep reducing the chances of intense sun shine. Despite a decrease in rainfall, September's humidity remains relatively high, slowly withdrawing its grip from the city.

Heat index
September's mean heat index is calculated to be a blistering 40°C (104°F). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.
Remember that heat index calculations are made for conditions in the shade with light wind. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. Rising body temperatures due to excess heat retention could signify impending heat disorders.
