Weather in September
Temperature
September brings a marginal elevation to a still hot 86.7°F (30.4°C) from August's 90°F (32.2°C) in Jennings's average high-temperatures. Jennings, in September, experiences an average temperature of 70.9°F (21.6°C) at night.Heat index
Throughout September, the heat index is calculated to be a sweltering 100.4°F (38°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.Heat index evaluations are typically in the context of light winds and shaded environments. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a composite of temperature and humidity figures to convey how warm it 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. 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 particularly relevant to children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
