Weather in September
Temperature
The arrival of September is marked by an average high-temperature of a still hot 88.7°F (31.5°C), bearing a close resemblance to August. An average nighttime temperature of 74.1°F (23.4°C) is recorded during September.Heat index
The heat index in September is calculated to be a blisteringly hot 105.8°F (41°C). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.Be informed that the heat index values are oriented around shady conditions and gentle breezes. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical to babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
