August's advent denotes a minor fluctuation in the average high-temperature to a moderately hot 85.3°F (29.6°C) from July's 87.1°F (30.6°C). The average temperature during August nights dips to a refreshing 66°F (18.9°C).

Heat index

The heat index value for August is appraised at a very hot 96.8°F (36°C). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.
It is emphasized that the heat index's values are meant for shaded zones with mild winds. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. 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.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
