Weather in August
Temperature
August's onset records an average high-temperature of a still tropical 86.5°F (30.3°C), a near match to July's 88.3°F (31.3°C). During the month of August, Jackson experiences a steady low-temperature average of 66.6°F (19.2°C).Heat index
In August, the heat index is calculated to be a very hot 98.6°F (37°C). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.Research indicates the heat index considers values in shaded locales and with light winds. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', gives an indication of how one might feel in terms of heat after considering humidity. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. 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 highly important for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. Be aware that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. and try to reduce direct sun exposure during this period as much as possible. Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage.
