Weather in September
Temperature
With September's onset, the weather reveals a slight temperature decrease, transitioning from a fiery hot 96.6°F (35.9°C) in August to a tropical 89.1°F (31.7°C). Nighttime temperatures in September average to a pleasant 71.6°F (22°C).Heat index
September's average heat index is computed to be a sweltering 102.2°F (39°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.Heat index specifics point out values are for conditions of shade and a slight breeze. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', determines the feeling of heat when you account for the relative humidity. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
