Weather in August
Temperature
On the advent of August, Livermore's average high-temperature exhibits a minor adjustment to a moderately hot 85.3°F (29.6°C) from July's 86°F (30°C). August's nights exhibit a sharp contrast from day highs, with an average temperature of 56.7°F (13.7°C).Heat index
The heat index in August is calculated to be a tropical 89.6°F (32°C). Enduring exposure and continuous activity might cause a feeling of tiredness and induce heat cramps.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.

Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
