Weather in September
Temperature
As September commences, the average high-temperature subtly reduces, transitioning from a tropical 90.1°F (32.3°C) in August to a moderately hot 83.7°F (28.7°C). September is noted for a mean low-temperature of 63.1°F (17.3°C).Heat index
For September, the heat index is estimated at a tropical 91.4°F (33°C). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.Always consider that heat index estimations are for light winds and places in the shade. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
