Weather in July
Temperature
California's July weather, marked by an average high temperature of 88.5°F (31.4°C) and an average low temperature of 68.2°F (20.1°C), is the warmest in the year.Heat index
In July, the heat index is appraised at an extremely hot 104°F (40°C). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly important for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. As body temperatures escalate without effective heat release, one might face dehydration threats.
Humidity
In California, the average relative humidity in July is 74%.Rainfall
In July, the rain falls for 16.6 days. Throughout July, 3.27" (83mm) of precipitation is accumulated. Throughout the year, in California, there are 142 rainfall days, and 32.13" (816mm) of precipitation is accumulated.Snowfall

Sunshine
In California, the average sunshine in July is 10.2h.UV index
June through August, with an average maximum UV index of 6, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV radiation for the ordinary person.Note: A maximum high daily UV index of 6 during July translates into the following directions:
Skirt overexposure. People with light complexions might get scorched in under 20 minutes. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. A wide-brim hat offers excellent sun protection for the eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure.
