Weather in August
Temperature
The beginning of August reveals an average high-temperature of a still hot 88.3°F (31.3°C), showing minimal deviation from the previous month. August nights are marked by an average temperature drop to a pleasant 70.7°F (21.5°C).Heat index
The heat index value for August is evaluated at a fiery hot 102.2°F (39°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.Heat index guidelines indicate values are for light wind scenarios and shaded regions. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a value derived by merging air temperature with the humidity to convey how the climate feels. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
