The last month of the summer, August, is another tropical month in Allen, Oklahoma, with an average temperature varying between 71.2°F (21.8°C) and 92.1°F (33.4°C).

Temperature

August temperatures tend to peak at an average high of 92.1°F (33.4°C) and dip to a low of 71.2°F (21.8°C).

Heat index

The heat index value during August is evaluated at an extremely hot 107.6°F (42°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.
The metrics for the heat index are tailored for both shady environments and light winds. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
