A moderate decline in average high-temperatures is noted in September, moving from a tropical 87.8°F (31°C) in August to a moderately hot 81°F (27.2°C). Nighttime temperatures in September average to a mild 60.3°F (15.7°C).Heat index
September's mean heat index is computed to be 84.2°F (29°C). With ongoing exposure and activity, one might experience weariness, and heat cramps could ensue.It is important to note that the heat index values are for shaded areas and light wind scenarios. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
