Weather in July
Temperature
Charleston's warmest month, July, generally records average temperatures ranging from a high of 86.4°F (30.2°C) to a low of 68.4°F (20.2°C).Heat index
The heat index in July is estimated at a sweltering 100.4°F (38°C). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.Given the heat index, its values are aligned with shaded sites and gentle winds. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are primarily vital for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.

Implement preventive steps and embrace sun safety standards. Protection from skin and eye distress is compulsory. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation.
