Weather in September
Temperature
The arrival of September signals a subtle shift in temperature, down from a hot 88.2°F (31.2°C) in August to a moderately hot 80.8°F (27.1°C). Nighttime temperatures in September average to a comfortable 62.2°F (16.8°C).Heat index
September's average heat index is estimated at 84.2°F (29°C). If one remains active during constant exposure, it might cause exhaustion and heat cramps.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
