Weather in August

August, the last month of the summer in Davis, is another hot month, with an average temperature fluctuating between 59.2°F (15.1°C) and 92.8°F (33.8°C).

Temperature

In August, Davis experiences a barely noticeable shift in meteorological conditions, with average high-temperatures moving from 93.6°F (34.2°C) in July to a still tropical 92.8°F (33.8°C). Nighttime temperatures exhibit a substantial dip from daytime highs during August, averaging at a mild 59.2°F (15.1°C).

Heat index

During August, the heat index is evaluated at a very hot 100.4°F (38°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.
For clarity, heat index numbers account for light winds and areas under shade. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', blends air temperature and moisture content to represent the felt temperature to humans. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Humidity

In Davis, the average relative humidity in August is 50%.

Rainfall

July and August are months with the least rain when the rain falls for 0.8 days and typically aggregates up to 0.04" (1mm) of rain.

Daylight

The average length of the day in August is 13h and 37min.
On the first day of August, sunrise is at 6:09 am and sunset at 8:16 pm. On the last day of the month, sunrise is at 6:36 am and sunset at 7:37 pm PDT.

Sunshine

In August, the average sunshine is 11.9h.

UV index

In August, the average daily maximum UV index is 6. A UV Index reading of 6 to 7 represents a high health risk from exposure to the Sun's UV radiation for average individuals.
Note: The maximum daily UV index of 6 in August converts into the following recommendations:
Implement preventive steps and embrace sun safety standards. Protection from skin and eye distress is compulsory. The Sun's UV radiation is most intense from 10 a.m. to 4 p.m. Try to avoid direct sun exposure during these hours. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key.
