Heat index

The average heat index in July is evaluated at a scorching 109.4°F (43°C). Warning: Heat cramps and heat exhaustion are anticipated. Heatstroke is a risk with ongoing activity.
Take into consideration that the heat index values are calculated for shade and light wind conditions. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'real feel', blends air temperature and moisture content to represent the felt temperature to humans. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
