Weather in September
Temperature
In the transition to September, Inman observes a minor drop in the average high-temperature, shifting from a tropical 89.2°F (31.8°C) in August to a warm 83.7°F (28.7°C). Inman throughout September, records an average low-temperature of 62.8°F (17.1°C).Heat index
September's heat index is computed to be a hot 89.6°F (32°C). Continuous exposure and activity could induce a sense of tiredness and subsequently, heat cramps.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. 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 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
