Weather in July

July, like June, is another hot summer month in Centerville, South Carolina, with an average temperature fluctuating between 69.4°F (20.8°C) and 91°F (32.8°C).

Temperature

The warmest time of the year is July, with temperatures averaging a high of 91°F (32.8°C) and a low of 69.4°F (20.8°C).

Heat index

July's heat index is computed to be a blisteringly hot 107.6°F (42°C). Incorporate additional safety actions, heat cramps and heat exhaustion are possible. Long-term activity may induce heatstroke.
Heat index evaluations are typically in the context of light winds and shaded environments. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. 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 meaningful for babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
