September's average heat index is evaluated at a torrid 100.4°F (38°C). Ensure additional precautions, heat exhaustion and heat cramps may be expected.

Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', unifies temperature and humidity readings to offer a comprehensive feel of warmth. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. As body temperatures escalate without effective heat release, one might face dehydration threats.
