Weather in September
Temperature
The commencement of September includes a gentle temperature shift, with the average high-temperature dropping a bit from a sweltering 95°F (35°C) in August to a tropical 88°F (31.1°C). September sees the temperature falling to a mean low of 68.9°F (20.5°C).Heat index
For most parts of September, the heat index is appraised at a very hot 98.6°F (37°C). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.The heat index's values are generally associated with conditions in shade and light breezes. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a value derived by merging air temperature with the humidity to convey how the climate feels. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important 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.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. 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.
