Weather in September
Temperature
As September unfolds, the average high-temperature reaches a still hot 86.9°F (30.5°C), hinting at a slight fluctuation from the previous month. During September, the average low-temperature is an agreeable 70°F (21.1°C).Heat index
The heat index for September is evaluated at a very hot 102.2°F (39°C). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', offers an insight into how hot it feels when we factor in moisture content. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
