Weather in September
Temperature
A mild shift in the average high-temperature occurs in September, reducing from a fiery hot 96.3°F (35.7°C) in August to a hot 89.1°F (31.7°C). In September, the average low-temperature records at a pleasant 69.3°F (20.7°C) during the nights.Heat index
September's average heat index is appraised at a blisteringly hot 104°F (40°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.Always consider that heat index estimations are for light winds and places in the shade. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', provides an understanding of perceived warmth by combining temperature and relative humidity. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
