Weather in September
Temperature
September's onset corresponds with a subtle shift in the average high-temperature, slightly moving from a tropical 90.7°F (32.6°C) in August to a moderately hot 85.3°F (29.6°C). Plantersville experiences an average low-temperature of 65.3°F (18.5°C) in month of September.Heat index
The heat index in September is computed to be a very hot 95°F (35°C). Adopt extra preventive measures, the occurrence of heat cramps and heat exhaustion is likely. Heatstroke may follow extended activity.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
