Weather in September
Temperature
The onset of September brings an average high-temperature of a still hot 88.3°F (31.3°C), nearly matching the August temperature. The month of September records an average low-temperature of 70°F (21.1°C).Heat index
In September, the average heat index is calculated to be an extremely hot 105.8°F (41°C). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.One should consider that heat index numbers are for shaded settings and light wind. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', joins air temperature with relative humidity to produce a temperature perception for humans. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular significance for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
