Weather in August
Temperature
August's average high-temperature is a moderately hot 85.5°F (29.7°C), maintaining a close comparison with July's 86.9°F (30.5°C). Throughout August, the nighttime temperature in Ladue averages to a refreshing 67.1°F (19.5°C).Heat index
For most parts of August, the heat index is computed to be a fiery hot 95°F (35°C). Incorporate additional safety actions, heat cramps and heat exhaustion are possible. Long-term activity may induce heatstroke.Keep in mind the heat index values are meant for areas in shade and with light wind. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
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. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Inhibit overexposure. Warding off sun damage is of utmost importance. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days.
