Weather in August
Temperature
During August, the average high-temperature is a still hot 91.4°F (33°C), maintaining a close resemblance to that of the preceding month. During August nights, Duncanville witnesses a consistent average temperature of 71.4°F (21.9°C).Heat index
The heat index in August is computed to be a life-threatening hot 113°F (45°C). Attention: Heat exhaustion and heat cramps are anticipated. Prolonged effort can result in heatstroke.Heat index's context suggests values are appropriate for shady areas and slight breezes. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are primarily vital for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Persist in precautions and follow sun safety policies. Keeping sunburn at bay is imperative. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. Sun-related eye harm can be minimized with proper sunglasses offering UVA and UVB coverage.
