Weather in August
Temperature
Vivian experiences an average high-temperature of a hot 94.6°F (34.8°C) in August, subtly different from July's 95°F (35°C). During August nights, Vivian records an average temperature of 73°F (22.8°C).Heat index
August's mean heat index is appraised at a life-threatening hot 118.4°F (48°C). Watchful: Heat cramps and heat exhaustion are predicted. Continued exertion could lead to heatstroke.In reference to the heat index, it's for places in shade and with a slight wind. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. 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 largely significant for babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds 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. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Inhibit overexposure. Warding off sun damage is of utmost importance. The Sun's UV radiation is at its strongest between the hours of 10 a.m. and 4 p.m. Minimize direct exposure to the sun during this period. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
