Heat index

In December, the heat index is calculated to be a blistering 41°C (105.8°F). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.
Heat index data is primarily for areas with shade and subjected to light winds. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
