The last month of the summer, August, is another tropical month in Altheimer, Arkansas, with temperature in the range of an average high of 90.7°F (32.6°C) and an average low of 72°F (22.2°C).

Temperature

As July turns into August, the average high-temperatures rest at a still tropical 90.7°F (32.6°C), showing a minor variation from the prior month. During August, Altheimer records an average temperature of 72°F (22.2°C) at night.

Heat index

For August, the heat index is estimated at an extremely hot 109.4°F (43°C). Forewarned: Heat cramps and heat exhaustion are anticipated. Ongoing physical activity increases the likelihood of heatstroke.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days.
