Weather in September
Temperature
The arrival of September marks a slight shift to an average high-temperature of a warm 83.1°F (28.4°C) from August's 87.3°F (30.7°C). September brings with it a nighttime average temperature of 64°F (17.8°C).Heat index
In September, the average heat index is calculated to be 84.2°F (29°C). If one stays active during extended exposure, it might induce fatigue and result in heat cramps.Be aware that heat index ratings are designed for shaded locations and minor breezes. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
