Weather in August

During August, Carlinville observes a subtle ascent to a still warm 82.6°F (28.1°C) from July's 83.8°F (28.8°C) in the average high-temperature. Nighttime temperatures in August average to a refreshing 64.9°F (18.3°C).Heat index
The heat index for August is estimated at a tropical 89.6°F (32°C). When exposure and activity are sustained, they could induce fatigue, with a chance of heat cramps.In the scope of the heat index, its values resonate with shade and light wind conditions. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
