Weather in August
Temperature
McDonough's weather in August indicates an average high-temperature of a still hot 88.9°F (31.6°C), nearly consistent with the 90.5°F (32.5°C) of July. McDonough experiences a nighttime temperature average of 70.2°F (21.2°C) during August.Heat index
August's average heat index is appraised at a blisteringly hot 105.8°F (41°C). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.It is important to note that the heat index values are for shaded areas and light wind scenarios. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

Sunshine

In August, the average daily maximum UV index is 6. A UV Index estimate of 6 to 7 represents a high threat to health from exposure to the Sun's UV radiation for ordinary individuals.Note: In August, the maximum UV index of 6 transforms into these recommendations:
Guard against overexposure. Protection from sun-induced harm is essential. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. Fend off the sun's harsh rays with appropriate clothing, a wide-brim hat, and UV-protective sunglasses.
