Heat index

The heat index for July is appraised at a burning hot 116.6°F (47°C). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.
Factoring in the heat index, values are geared towards shaded areas with light breezes. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are primarily vital for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
