Weather in September
Temperature
September ushers in a minute temperature change, with average high-temperatures reducing from August's hot 87.6°F (30.9°C) to a moderately hot 82°F (27.8°C). Light reports an average nighttime low-temperature of 63.5°F (17.5°C) in September.Heat index
The average heat index in September is evaluated at a hot 87.8°F (31°C). Enduring exposure and ongoing activity could cause a sense of fatigue and subsequent heat cramps.Heat index guidelines indicate values are for light wind scenarios and shaded regions. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', reflects the feeling of heat when considering both air temperature and humidity. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. 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.
