The last month of the summer, August, is another hot month in Arch, Oklahoma, with temperature in the range of an average low of 70.3°F (21.3°C) and an average high of 92.1°F (33.4°C).

Heat index

The heat index value for August is estimated at a blistering 109.4°F (43°C). Guard: Heat exhaustion and heat cramps are foreseeable. Prolonged effort may bring about heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', shows a temperature sensation when both heat and moisture conditions are combined. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
