Weather in September
Temperature
The arrival of September suggests a slight decrease in the average high-temperature, moving from 94.5°F (34.7°C) in August to a still hot 86.4°F (30.2°C). Star throughout September, experiences an average nighttime temperature of 68.9°F (20.5°C).Heat index
September's average heat index is calculated to be a tropical 93.2°F (34°C). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.Know that the heat index computations account for shaded terrains and slight winds. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
