Weather in September
Temperature
The onset of September entails a subtle temperature shift, as the average high-temperature eases from a hot 86.5°F (30.3°C) in August to a moderately hot 80.6°F (27°C). Piney Acres records a steady low-temperature average of 59.4°F (15.2°C) during September.Heat index
For most parts of September, the heat index is computed to be 84.2°F (29°C). If one remains active during constant exposure, it might cause exhaustion and heat cramps.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
