Weather in August
Temperature
The beginning of August records an average high-temperature of a still tropical 86.4°F (30.2°C), almost echoing the conditions of the previous month. In Mound City, the expected average low-temperature for August is a comfortable 67.5°F (19.7°C).Heat index
The average heat index in August is calculated to be a sweltering 98.6°F (37°C). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.When assessing, remember that heat index measurements are for light winds and shaded spots. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to babies and toddlers. 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.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
