Weather in August
Temperature
The dawn of August sees an average high-temperature of a still hot 88.9°F (31.6°C), subtly contrasting with July's 90.1°F (32.3°C). During the nights in August, Duncan observes an average low-temperature of 71.8°F (22.1°C).Heat index
The heat index value for August is computed to be a scorching 105.8°F (41°C). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.Keep in mind the heat index values are meant for areas in shade and with light wind. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'real feel', comes about by integrating the temperature readings with the humidity levels. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
Perspiration is essential for the human body; it facilitates cooling through the process of 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. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
