Weather in August
Temperature
Jackson sees its peak of temperatures during July and August, with an average high-temperature of 91.8°F (33.2°C).Heat index
The heat index value during August is estimated at a life-threatening hot 113°F (45°C). Stay mindful: Heat exhaustion and heat cramps are likely. Heatstroke could follow extended physical effort.In the scope of the heat index, its values resonate with shade and light wind conditions. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'feels like' or 'apparent temperature', arises from combining readings of air temperature and relative moisture content. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. 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 of high significance for 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.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
