September's mean heat index is appraised at a very hot 38°C (100.4°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes.

Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', gauges the sensation of temperature factoring in the air's moisture content. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. 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 essentially critical for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
