Weather in September
Temperature
September brings a slight decrease in the average high-temperature, shifting from a hot 86.5°F (30.3°C) in August to a moderately hot 81°F (27.2°C). September nights experience a consistent temperature drop to an enjoyable 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 are sustained, they might cause a feeling of weariness, resulting in heat cramps.It is important to note that the heat index values are for shaded areas and light wind scenarios. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
