Weather in September
Temperature
A moderate decline in average high-temperatures is noted in September, moving from a tropical 86.5°F (30.3°C) in August to a warm 80.8°F (27.1°C). An average low-temperature of 60.6°F (15.9°C) is noted during the nights in September.Heat index
For most parts of September, the heat index is computed to be 84.2°F (29°C). Prolonged activity during exposure might result in a state of fatigue and cause heat cramps.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', gives an indication of how one might feel in terms of heat after considering humidity. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant 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.
