Weather in August

August, the last month of the summer in Gray Summit, is also a hot month, with an average temperature fluctuating between 66.7°F (19.3°C) and 86.5°F (30.3°C).

Temperature

The average high-temperature in August, at a still tropical 86.5°F (30.3°C), reveals a modest deviation from July's 88.2°F (31.2°C). In the month of August, the temperature generally rests at an average low of 66.7°F (19.3°C).

Heat index

For most parts of August, the heat index is calculated to be a very hot 98.6°F (37°C). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance 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.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
