Heat index

The heat index for September is estimated at a torrid 95°F (35°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Note: A maximum UV index of 6 in September translates into the following recommendations:
Deter overexposure. Protecting against the sun's effects is essential. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat. Caution! The reflection of sand and water significantly amplifies the Sun's UV radiation.
