Heat index

August's heat index is appraised at a blisteringly hot 105.8°F (41°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
Understand that the heat index values take into account shaded locations and mild winds. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Note: In August, the maximum UV index of 7 translates into these guidelines:
Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun.
