August, the last month of the summer in Cottonwood Grove, is another hot month, with temperature in the range of an average low of 68.5°F (20.3°C) and an average high of 86.4°F (30.2°C).

Heat index

For August, the heat index is computed to be a sweltering 100.4°F (38°C). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.
Factoring in the heat index, values are geared towards shaded areas with light breezes. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', shows a temperature sensation when both heat and moisture conditions are combined. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
