Weather in September
Temperature
An average high-temperature of a still hot 86.7°F (30.4°C) marks September, exhibiting a close resemblance to the conditions in August. During the nights in September, the temperature averages to a pleasant 69.6°F (20.9°C).Heat index
For September, the heat index is evaluated at a very hot 98.6°F (37°C). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.Evaluating the heat index requires understanding its values in the shade and with gentle winds. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
