Weather in August
Temperature
Rock Hill's shift from July to August is accompanied by an average high-temperature of a still hot 90.5°F (32.5°C), a slight deviation from 90.9°F (32.7°C). In August, Rock Hill encounters an average low-temperature of 75.6°F (24.2°C) during the night.Heat index
The heat index for August is evaluated at a blisteringly hot 111.2°F (44°C). Remain cautious: Heat cramps along with heat exhaustion are foreseeable. Ongoing activity may precipitate heatstroke.Heat index values are typically calculated for conditions of shade and a light breeze. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is achieved by amalgamating air temperature with the relative humidity readings. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

In August, the average relative humidity is 74%.Rainfall
The month with the most rainfall is August, when the rain falls for 21.3 days and typically aggregates up to 2.95" (75mm) of precipitation.Snowfall

Sunshine

May through August, with an average maximum UV index of 7, are months with the highest UV index. A UV Index reading of 6 to 7 represents a high threat to health from exposure to the Sun's UV radiation for average individuals.Note: A maximum UV index of 7 in August translates into the following recommendations:
Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat.
