Weather in September
Temperature
With the transition into September, McLeods Mill notes an average high-temperature of a still tropical 86.4°F (30.2°C), closely resembling August. Throughout September, the average low-temperature dips to a pleasant 69.8°F (21°C).Heat index
The heat index for September is evaluated at a torrid 98.6°F (37°C). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.Heat index values are typically calculated for conditions of shade and a light breeze. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. 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 primarily vital for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
