Weather in August
Temperature
Cheyenne sees the arrival of August with an average high-temperature of a still tropical 94.1°F (34.5°C), indicating a subtle variation from July. Despite a significant disparity with daytime temperatures, an average low-temperature of 72.1°F (22.3°C) is recorded during August.Heat index
For August, the heat index is calculated to be a scorching 104°F (40°C). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.The heat index's values are generally associated with conditions in shade and light breezes. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', quantifies the warmth felt when relative humidity is considered. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. 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 are extremely significant for babies and toddlers. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
