Weather in August
Temperature
August experiences an average high-temperature of a still hot 90.3°F (32.4°C), barely different from July's 91°F (32.8°C). An average low-temperature of 72.1°F (22.3°C) is observed during August nights.Heat index
During August, the heat index is computed to be a blazing hot 113°F (45°C). Guard: Heat exhaustion and heat cramps are foreseeable. Prolonged effort may bring about heatstroke.In the scope of the heat index, its values resonate with shade and light wind conditions. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', unifies temperature and humidity readings to offer a comprehensive feel of warmth. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.

Sunshine

In August, the average daily maximum UV index is 6. A UV Index estimate of 6 to 7 represents a high health hazard from exposure to the Sun's UV rays for ordinary individuals.Note: In August, a daily maximum UV index of 6 leads to the following instructions:
Guard against overexposure. Protection from sun-induced harm is essential. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. For effective sun eye protection, rely on sunglasses certified for UVA and UVB resistance.
