Heat index

For August, the heat index is calculated to be a blazing hot 116.6°F (47°C). Attention: Heat exhaustion and heat cramps are anticipated. Prolonged effort can result in heatstroke.
It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', reflects the feeling of heat when considering both air temperature and humidity. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. 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 quite important for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Remember, however, that shade structures may not provide complete protection. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key.
