Weather in August

In August, the heat index is evaluated at a torrid 96.8°F (36°C). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.When assessing, remember that heat index measurements are for light winds and shaded spots. With exposure to direct sunshine, the heat index could climb 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. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
