Weather in August

The last month of the summer, August, is also a hot month in Sims, Arkansas, with an average temperature ranging between max 90.1°F (32.3°C) and min 69.3°F (20.7°C).

Temperature

Transitioning from July to August, Sims observes an average high-temperature of a still tropical 90.1°F (32.3°C), differing subtly from the previous month. During August, Sims records an average temperature of 69.3°F (20.7°C) at night.

Heat index

The heat index value during August is evaluated at a blisteringly hot 107.6°F (42°C). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.
Know that the heat index computations account for shaded terrains and slight winds. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', integrates the air's temperature and its humidity to showcase the felt temperature by people. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Protect your eyes, ears, face, and neck from the Sun by wearing a wide-brimmed hat.
