Weather in August
Temperature
The onset of August notes an average high-temperature of a moderately hot 85.6°F (29.8°C), subtly shifted from July's 88.3°F (31.3°C). Keystone registers a marked temperature plunge to a comfortable 63°F (17.2°C) during the cool August nights.Heat index
Throughout August, the heat index is calculated to be a tropical 89.6°F (32°C). Staying active during long-term exposure might result in a state of exhaustion and cause heat cramps.Bear in mind that the heat index values are determined for shaded areas and light breezes. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.

Prevent overexposure. Protection from the sun's harmful effects is needed. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. A wide-brimmed hat provides unparalleled sun protection for sensitive areas like the eyes, ears, and neck.
