Weather in September
Temperature
An average high-temperature of a warm 82.9°F (28.3°C) marks September, exhibiting a close resemblance to the conditions in August. The average low-temperature during September nights is an enjoyable 62.6°F (17°C).Heat index

Exposure and extended activity could potentially cause a state of fatigue and lead to heat cramps.Keep in mind the heat index values are meant for areas in shade and with light wind. 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 'apparent temperature', is an estimation of the warmth sensation when considering humidity levels. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
