Weather in September
Temperature
Start of September brings a slight shift in the average high-temperature, dipping a bit from August's hot 87.4°F (30.8°C) to a warm 80.6°F (27°C). Hughes Corner's temperature tends to fall to an average low of 62.8°F (17.1°C) during the nights of September.Heat index
During September, the heat index is estimated at 84.2°F (29°C). Continuous exposure and activity could induce a sense of tiredness and subsequently, heat cramps.Research indicates the heat index considers values in shaded locales and with light winds. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold great significance to children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
