Weather in August
Temperature
Duncan, Tennessee, records a slight change with August's average high-temperatures adjusting to a still hot 86.7°F (30.4°C) from July's 87.6°F (30.9°C). From the height of daytime heat, the temperature recedes to an average of 64.4°F (18°C) at night during August.Heat index
The heat index in August is estimated at a fiery hot 98.6°F (37°C). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a single figure representing how weather conditions feel when combining temperature and humidity. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
