Weather in August
Temperature
The temperature hits its peak in July and August, recording an average high-temperature of 91.6°F (33.1°C).Heat index
The heat index value for August is calculated to be a life-threatening hot 114.8°F (46°C). Notice: Heat cramps and heat exhaustion are likely. Continued strenuous activity might lead to heatstroke.Always consider that heat index estimations are for light winds and places in the shade. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a composite of temperature and humidity figures to convey how warm it feels. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
