Weather in August

The heat index in August is evaluated at a fiery hot 102.2°F (39°C). Adopt extra safety steps, risk of heat exhaustion and heat cramps is notable. Sustained activity might cause heatstroke.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', comes about by integrating the temperature readings with the humidity levels. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
