Weather in August
Temperature
The shift from July to August is characterized by an average high-temperature of a still hot 90.3°F (32.4°C), not significantly different from the 91°F (32.8°C) of July. Atherton's temperature in August lowers to a consistent average of 72.7°F (22.6°C) during the nights.Heat index
For August, the heat index is evaluated at an extremely hot 111.2°F (44°C). Take note: Heat exhaustion and heat cramps are expected. Heatstroke can occur with prolonged effort.Remember that heat index calculations are made for conditions in the shade with light wind. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

Sunshine

The months with the highest UV index are June through August, with an average maximum UV index of 7. A UV Index of 6 to 7 symbolizes a high health vulnerability from exposure to the Sun's UV radiation for ordinary individuals.Note: The UV index of 7 during August translates into the following guidance:
Guard oneself from overexposure. Defence against sun injury is vital. It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
