July and August are identified as the warmest months, with an average high-temperature of 93.4°F (34.1°C).Heat index
For most parts of August, the heat index is calculated to be a burning hot 116.6°F (47°C). Stay watchful: Heat exhaustion along with heat cramps are likely. Ongoing effort may cause heatstroke.Realize that the values for the heat index are set for shaded places and light winds. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', takes into account both air temperature and humidity to illustrate what people actually feel. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
