Weather in September
Temperature
With September's onset, the weather reveals a slight temperature decrease, transitioning from 93.9°F (34.4°C) in August to a still hot 88°F (31.1°C). Throughout September nights, Bradley experiences a consistent temperature average of 66.7°F (19.3°C).Heat index
The average heat index in September is appraised at a torrid 100.4°F (38°C). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.It is important to note that the heat index values are for shaded areas and light wind scenarios. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
