Weather in August
Temperature
As July transitions into August, the average high-temperature rests at a still hot 88.3°F (31.3°C), maintaining a close resemblance to the previous month. During August, Big Sandy's temperature averages to an enjoyable 67.6°F (19.8°C) at night.Heat index
The heat index in August is evaluated at a scorching 104°F (40°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.Evaluating the heat index requires understanding its values in the shade and with gentle winds. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', reflects the blend of air temperature and relative humidity to give a temperature impression. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely vital to babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

The average relative humidity in August is 75%.Rainfall
In August, the rain falls for 12.5 days. Throughout August, 1.85" (47mm) of precipitation is accumulated. Throughout the year, there are 136.3 rainfall days, and 20.55" (522mm) of precipitation is accumulated.Snowfall

Sunshine

May through August, with an average maximum UV index of 6, are months with the highest UV index. A UV Index value of 6 to 7 symbolizes a high health vulnerability from exposure to the Sun's UV radiation for the ordinary person.Note: The maximum daily UV index of 6 in August interprets into the following recommendations:
Eschew overexposure. Those with light skin may suffer burns in fewer than 20 minutes. To the best of your ability, limit your exposure to the sun between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
