Weather in September
Temperature
The unfolding of September shows an average high-temperature of a still hot 87.4°F (30.8°C), indicating a slight variance from August's 91.9°F (33.3°C). An average nighttime temperature of 68.4°F (20.2°C) is noted during the month of September.Heat index
For most parts of September, the heat index is computed to be a torrid 102.2°F (39°C). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.Note that heat index values are valued for light wind and location in the shade. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', combines air temperature and relative humidity to represent a human perceived temperature equivalent. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
