Weather in September
Temperature
September's arrival shows an average high-temperature of a moderately hot 85.8°F (29.9°C), hardly different from the previous month. During the nights in September, the temperature averages to an enjoyable 65.5°F (18.6°C).Heat index
September's average heat index is estimated at a very hot 95°F (35°C). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.The metrics for the heat index are tailored for both shady environments and light winds. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an estimation of the warmth sensation when considering humidity levels. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. 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.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
