Weather in September
Temperature
A moderate decline in average high-temperatures is noted in September, moving from a very hot 99°F (37.2°C) in August to a hot 92.7°F (33.7°C). September brings with it a nighttime average temperature of 77.2°F (25.1°C).Heat index
The heat index value during September is calculated to be an extremely hot 109.4°F (43°C). Beware: Heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.It is important to note that the heat index values are for shaded areas and light wind scenarios. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', determines the feeling of heat when you account for the relative humidity. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
