Heat index

For September, the heat index is computed to be a life-threatening hot 47°C (116.6°F). Be wary: Heat exhaustion and heat cramps are highly anticipated. With continued activity, heatstroke is very likely.
When considering the heat index, it's pivotal to note it is for shade and mild 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 'apparent temperature' or 'real feel', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are of high significance for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.

Eschew overexposure. Those with light skin may suffer burns in fewer than 20 minutes. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. Employ a hat with a wide brim for robust protection, cutting UV exposure by half.
