Weather in September
Temperature
September marks a gentle change in average high-temperature, declining from August's tropical 88.7°F (31.5°C) to a moderately hot 82.2°F (27.9°C). In September, the temperature in Sandtown drops to an average of 62.4°F (16.9°C) at night.Heat index
September's average heat index is evaluated at a hot 87.8°F (31°C). Uninterrupted activity during exposure could lead to a sense of exhaustion, possibly causing heat cramps.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
