Weather in August
Temperature
With the onset of August, the average high-temperature stands at a still tropical 91°F (32.8°C), closely aligned with July's 91.4°F (33°C). During August nights, Roxie records an average temperature of 72.3°F (22.4°C).Heat index
In August, the average heat index is calculated to be a burning hot 113°F (45°C). Observe: Heat exhaustion and heat cramps are probable. Heatstroke is on the horizon with prolonged exertion.Data suggests that the heat index is set for environments in shade and with a light wind. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly meaningful for babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

The month with the most rainfall is August, when the rain falls for 19.5 days and typically aggregates up to 3.9" (99mm) of precipitation.Snowfall

Sunshine

June through August, with an average maximum UV index of 7, are months with the highest UV index. A UV Index value of 6 to 7 symbolizes a high health hazard from unsafe exposure to UV radiation for average individuals.Note: The daily high UV index of 7 in August translates into this advice:
Follow precautions and abide by sun safety rules. Deterrence of sunburn is imperative. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. During bright days, sunglasses that offer UVA and UVB defense are recommended.
