September, the first month of the autumn in Augustin, is still a tropical month, with an average temperature fluctuating between 67.1°F (19.5°C) and 87.6°F (30.9°C).

The onset of September brings an average high-temperature of a still hot 87.6°F (30.9°C), nearly matching the August temperature. During the September nights, an average temperature of 67.1°F (19.5°C) is observed.

Heat index

Throughout September, the heat index is appraised at a very hot 100.4°F (38°C). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.
The heat index's values are generally associated with conditions in shade and light breezes. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
