Weather in August
Temperature
August, known for its average high temperature of 96.1°F (35.6°C) and an average low temperature of 76.6°F (24.8°C), is the warmest month.Heat index
For most parts of August, the heat index is estimated at a blisteringly hot 111.2°F (44°C). Remain alert: Heat exhaustion and heat cramps are predicted. Extended effort can lead to heatstroke.Consider that heat index readings are for situations in the shade and light wind. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
