Weather in August
Temperature
The advent of August sees the average high-temperature at a still hot 86.7°F (30.4°C), subtly shifted from July's 88.7°F (31.5°C). Pilot Knob's August nights represent a significant downturn from the day's heat, with an average temperature of 65.1°F (18.4°C).Heat index
For most parts of August, the heat index is appraised at a sweltering 100.4°F (38°C). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.It is essential to grasp that the heat index's numbers are for shade and light wind settings. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

Sunshine

May through August, with an average maximum UV index of 6, are months with the highest UV index. A UV Index reading of 6 to 7 represents a high health risk from unsafe exposure to UV radiation for the ordinary person.Note: The UV index of 6 during August leads to these advisories:
Uphold preventive measures and conform to sun safety guidelines. Defending against skin and eye harm is crucial. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. Employ a wide-brim hat for potent defense against up to 50% of UV rays.
