Weather in August
Temperature
The weather during August records an average high-temperature of a still warm 83.1°F (28.4°C), closely mirroring the preceding month. Rileyville documents a striking divergence from daytime highs, with an average nighttime temperature of 61.3°F (16.3°C) in August.Heat index
The average heat index in August is calculated to be a tropical 89.6°F (32°C). When exposure and activity are sustained, they could induce fatigue, with a chance of heat cramps.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', melds the effects of warmth and moisture to generate a feeling of heat. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly important for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
