The last month of the summer, August, is also a hot month in Dalark, Arkansas, with temperature in the range of an average low of 71.1°F (21.7°C) and an average high of 92.8°F (33.8°C).

Temperature

The average high-temperature is a still hot 92.8°F (33.8°C) in August, hardly different from the 93.2°F (34°C) recorded in July. Dalark's average nighttime temperatures present a clear contrast to its daytime highs, measured at a pleasant 71.1°F (21.7°C) in August.

Heat index

August's mean heat index is estimated at a burning hot 116.6°F (47°C). Be wary: Heat exhaustion and heat cramps are highly anticipated. With continued activity, heatstroke is very likely.
Be informed that the heat index values are oriented around shady conditions and gentle breezes. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', marries air temperature and humidity to produce a value illustrating perceived warmth. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
