Weather in September
Temperature
September's arrival subtly correlates with a reduction in the average high-temperature, down from a hot 87.1°F (30.6°C) in August to a moderately hot 81.5°F (27.5°C). During September, Nunnelly observes a consistent average nighttime temperature of 61.9°F (16.6°C).Heat index
The average heat index in September is calculated to be a tropical 86°F (30°C). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.Records show heat index calculations are tailored for shaded regions and mild winds. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is achieved by amalgamating air temperature with the relative humidity readings. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. 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.
