Weather in September
Temperature
The arrival of September sees an average high-temperature of a still tropical 87.8°F (31°C), hardly diverging from August's 91.8°F (33.2°C). In September, the average low-temperature is a pleasant 69.3°F (20.7°C).Heat index
The heat index for September is calculated to be an extremely hot 104°F (40°C). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
