Weather in August
Temperature
Morrilton transitions into August recording an average high-temperature of a still tropical 90.9°F (32.7°C), closely aligning with the preceding month's temperature. An average low-temperature of 69.4°F (20.8°C) is noted during the nights in August.Heat index
During August, the heat index is calculated to be a blistering 111.2°F (44°C). Beware: Heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.Heat index's context suggests values are appropriate for shady areas and slight breezes. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
