Weather in August
Temperature
During August, Duncan records an average high-temperature of a still tropical 88.9°F (31.6°C), marking a slight divergence from July's 90.1°F (32.3°C). In Duncan, the expected average low-temperature for August is an agreeable 71.8°F (22.1°C).Heat index
In August, the heat index is evaluated at an extremely hot 105.8°F (41°C). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a value derived by merging air temperature with the humidity to convey how the climate feels. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular significance for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

Keep in mind that shade structures may not provide complete protection. Sunglasses providing both UVA and UVB protection are non-negotiable on sunlit days.
