Weather in August
Temperature
Table Grove, Illinois, records an average high-temperature of a still moderately hot 81.9°F (27.7°C) in August, maintaining a close correlation with July's 82.4°F (28°C). Throughout August in Table Grove, a steady low-temperature average of 63.7°F (17.6°C) is noted.Heat index
August's mean heat index is computed to be a tropical 87.8°F (31°C). When exposure and activity are sustained, they could induce fatigue, with a chance of heat cramps.The standards for the heat index are set for locations in shade and under light breezes. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a measure of how hot it feels when the actual air humidity is factored in. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
