Temperature

August, with its average high-temperature of 90.9°F (32.7°C) and an average low-temperature of 75.7°F (24.3°C), holds the record as the warmest month.

Heat index

For most parts of August, the heat index is computed to be a life-threatening hot 114.8°F (46°C). Keep guard: Heat cramps and heat exhaustion are likely. Continued activity increases the risk of heatstroke.
In reference to the heat index, it's for places in shade and with a slight wind. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
