Heat index

The heat index in July is computed to be a blisteringly hot 109.4°F (43°C). Notice: Heat cramps and heat exhaustion are likely. Continued strenuous activity might lead to heatstroke.
The metrics for the heat index are tailored for both shady environments and light winds. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', melds the effects of warmth and moisture to generate a feeling of heat. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
