Weather in September

The commencement of September indicates a gentle shift in the average high-temperature, receding from August's tropical 88.7°F (31.5°C) to a warm 83.3°F (28.5°C). An average low-temperature of 63.1°F (17.3°C) is noted during the nights in September.Heat index
The heat index for September is appraised at a tropical 89.6°F (32°C). Prolonged exposure and physical activity might induce exhaustion, potentially causing heat cramps.Keep in mind the heat index values are meant for areas in shade and with light wind. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. 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.
