Weather in September
Temperature
The beginning of September records an average high-temperature of a still hot 86.5°F (30.3°C), marking a negligible difference from August's 90.7°F (32.6°C). Pine Prairie records a consistent low-temperature of 69.4°F (20.8°C) during September nights.Heat index
The heat index value for September is evaluated at a fiery hot 100.4°F (38°C). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.In terms of the heat index, values are set with light wind and shade conditions in mind. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', offers an insight into how hot it feels when we factor in moisture content. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
