Weather in June
Temperature
Livermore's June weather indicates a minor increase in high-temperatures, edging from May's pleasant 73°F (22.8°C) to a moderately hot 81.1°F (27.3°C). A considerable shift from the daytime highs is observed during June nights, with an average low of 53.6°F (12°C).Heat index
For June, the heat index is calculated to be 82.4°F (28°C). If activity and exposure persist, they could induce fatigue, leading to possible heat cramps.Heat index determinations are made taking into account the shade and light air movements. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', quantifies the warmth felt when relative humidity is considered. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.

A UV Index value of 6 to 7 symbolizes a high health hazard from unsafe exposure to UV radiation for average individuals.Note: An average UV index of 6 in June transforms into this advice:
Undertake precautions and comply with sun safety standards. Protection from skin and eye injury is vital. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. Employ a wide-brim hat for potent defense against up to 50% of UV rays.
