Weather in August
Temperature
August's average high-temperature is a still warm 84.4°F (29.1°C), maintaining a close comparison with July's 85.6°F (29.8°C). Throughout August, the temperature tends to fall to a consistent average low of 65.8°F (18.8°C).Heat index
The heat index value for August is evaluated at a torrid 95°F (35°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.The standards for the heat index are set for locations in shade and under light breezes. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
