Weather in August
Temperature
With an average high-temperature of 93.4°F (34.1°C) and an average low-temperature of 72.1°F (22.3°C), August is the warmest month.Heat index
In August, the heat index is appraised at a blisteringly hot 109.4°F (43°C). Note: Heat exhaustion and heat cramps are probable. Heatstroke can follow with prolonged activity.Observations indicate that the heat index values are for shady locations with light wind. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is a single figure representing how weather conditions feel when combining temperature and humidity. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. 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 cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Undertake protective measures and comply with sun safety rules. Shielding against skin and eye damage is essential. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
