In August, Bella Vista, Arkansas still finds itself caught in the grasp of summers, albeit with a slight cooling trend noticeable as compared to July. The hazy glow of the sun continues to be a familiar sight with long sunny days. Heatwaves do not prevail, providing moments of respite to the residents. August ushers in the final symphony of summer, composed of long daylight hours and moderately high temperatures.

Temperature

The dawn of August sees an average high-temperature of a still tropical 88.2°F (31.2°C), subtly contrasting with July's 89.6°F (32°C). Bella Vista in August anticipates an average nighttime temperature of 66.7°F (19.3°C).

Heat index

August's mean heat index is evaluated at a fiery hot 102.2°F (39°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
