Heat index

In October, the heat index is computed to be a burning hot 47°C (116.6°F). Keep guard: Heat cramps and heat exhaustion are likely. Continued activity increases the risk of heatstroke.
Given the heat index, its values are aligned with shaded sites and gentle winds. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital 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.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
