Heat index

September's average heat index is calculated to be a life-threatening hot 49°C (120.2°F). Notice: Heat cramps and heat exhaustion are likely. Continued strenuous activity might lead to heatstroke.
Heat index guidelines indicate values are for light wind scenarios and shaded regions. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', blends air temperature and moisture content to represent the felt temperature to humans. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Deter overexposure. Protecting against the sun's effects is essential. To the best of your ability, limit your exposure to the sun between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Select sunglasses that boast both UVA and UVB protection to limit the adverse effects of the sun on the eyes.
