Weather in August
Temperature
August is marked by an average high-temperature of a still tropical 93.6°F (34.2°C), almost identical to the preceding month. Manteca observes a dramatic plunge from daytime highs in August, settling at an average low-temperature of 59.9°F (15.5°C).Heat index
The heat index in August is estimated at a sweltering 98.6°F (37°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.When assessing, remember that heat index measurements are for light winds and shaded spots. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
Humidity
The average relative humidity in August is 45%.Rainfall
July and August are months with the least rain when the rain falls for 1.2 days and typically aggregates up to 0.08" (2mm) of rain.Snowfall

Sunshine
In Manteca, the average sunshine in August is 12h.UV index
In August, the average daily maximum UV index is 6. A UV Index value of 6 to 7 symbolizes a high health vulnerability from unsafe exposure to UV radiation for average individuals.Note: The daily maximum UV index of 6 in August interprets into the following advice:
Implement precautions and maintain sun safety methods. Avoidance of sunburn is demanded. 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. Stay sun-safe with clothing that is both closely woven and worn loosely.
