Weather in August
Temperature
California marks the arrival of August with an average high-temperature of a still tropical 86.5°F (30.3°C), hardly different from July's 88.5°F (31.4°C). An average low-temperature of 65.7°F (18.7°C) marks the month of August.Heat index
The heat index in August is appraised at a very hot 98.6°F (37°C). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.Data suggests that the heat index is set for environments in shade and with a light wind. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

June through August, with an average maximum UV index of 6, are months with the highest UV index. A UV Index of 6 to 7 symbolizes a high health vulnerability from exposure to the Sun's UV rays for the ordinary person.Note: An average maximum UV index of 6 in August leads to these recommendations:
Enforce precautions and stick to sun safety measures. Preservation from skin and eye damage is essential. UV radiation from the sun is at its strongest between 10 a.m. and 4 p.m. Try to limit direct exposure during these hours. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
