Weather in July

July, like June, is another tropical summer month in Winnsboro, South Carolina, with an average temperature fluctuating between 71.8°F (22.1°C) and 91.6°F (33.1°C).

Temperature

July, known for its average high temperature of 91.6°F (33.1°C) and an average low temperature of 71.8°F (22.1°C), is the warmest month.

Heat index

The average heat index in July is evaluated at an extremely hot 111.2°F (44°C). Vigilance: Heat cramps and heat exhaustion are likely. The likelihood of heatstroke increases with continued activity.
For clarity, heat index numbers account for light winds and areas under shade. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. 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, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Rising body temperatures due to excess heat retention could signify impending heat disorders.
