Heat index

The heat index value for August is estimated at a blazing hot 114.8°F (46°C). Mindful: Heat cramps and heat exhaustion are to be expected. Extended physical effort might result in heatstroke.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a value derived by merging air temperature with the humidity to convey how the climate feels. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. 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 hold particular significance for children. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
