Weather in September
Temperature
September's weather records an average high-temperature of a still hot 30.1°C (86.2°F), showing little deviation from August. During September, the average low-temperature is a warm 24.7°C (76.5°F).Heat index
For most parts of September, the heat index is evaluated at a fiery hot 38°C (100.4°F). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', offers an insight into how hot it feels when we factor in moisture content. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are quite important for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
