Weather in August
Temperature
Mountain in August witnesses an average high-temperature of a still warm 83.8°F (28.8°C), indicating a slight variation from July's 84.7°F (29.3°C). Despite a stark disparity with daily highs, Mountain records an average nighttime temperature of 60.6°F (15.9°C) in August.Heat index
August's mean heat index is evaluated at a tropical 93.2°F (34°C). Adopt extra preventive measures, the occurrence of heat cramps and heat exhaustion is likely. Heatstroke may follow extended activity.It is important to note that the heat index values are for shaded areas and light wind scenarios. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', combines both the air temperature and the humidity level to give a perceived human temperature. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical to babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
