Weather in September
Temperature
September's arrival aligns with a minor decrease in average high-temperatures, from August's hot 86.7°F (30.4°C) to a moderately hot 81.1°F (27.3°C). September's average low-temperature reading settles at a refreshing 61.7°F (16.5°C).Heat index
September's heat index is evaluated at a tropical 86°F (30°C). If one stays active during extended exposure, it might induce fatigue and result in heat cramps.The metrics for the heat index are tailored for both shady environments and light winds. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', combines both the air temperature and the humidity level to give a perceived human temperature. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. 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 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.
