Weather in August
Temperature
During August, Livermore observes a subtle ascent to a moderately hot 85.3°F (29.6°C) from July's 86°F (30°C) in the average high-temperature. Despite the hot August days, Livermore's nights see an average temperature plunge to a refreshing 56.7°F (13.7°C).Heat index
Throughout August, the heat index is appraised at a tropical 89.6°F (32°C). Uninterrupted exposure and activity might result in fatigue, potentially causing heat cramps.It is important to note that the heat index values are for shaded areas and light wind scenarios. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', integrates the air's temperature and its humidity to showcase the felt temperature by people. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.

June through August, with an average maximum UV index of 6, are months with the highest UV index in Livermore. A UV Index reading of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV radiation for ordinary individuals.Note: The daily high UV index of 6 in August translates into this advice:
Stay clear of intense sun exposure. Solar protection is of utmost significance. Be aware that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. and try to reduce direct sun exposure during this period as much as possible. For excellent sun protection for the eyes, ears, face, and neck, consider a wide-brim hat.
