The last month of the summer, August, is another tropical month in Shumaker, Arkansas, with temperature in the range of an average low of 71.8°F (22.1°C) and an average high of 93°F (33.9°C).

Temperature

The introduction of August sees an average high-temperature of a still hot 93°F (33.9°C), hardly deviating from July. In the month of August, the average temperature dips to a pleasant 71.8°F (22.1°C) during the night.

Heat index

For August, the heat index is calculated to be a life-threatening hot 116.6°F (47°C). Forewarned: Heat cramps and heat exhaustion are anticipated. Ongoing physical activity increases the likelihood of heatstroke.
Note that heat index values are valued for light wind and location in the shade. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a metric representing the sensation of warmth when air temperature and moisture come together. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
