Weather in July
Temperature
Columbia experiences its highest average temperatures in July, reaching a peak of 93.7°F (34.3°C) and a minimum of 72.9°F (22.7°C).Heat index
July's mean heat index is calculated to be a blazing hot 122°F (50°C). On guard: Heat exhaustion and heat cramps are predicted. Heatstroke is a potential hazard with continuous physical effort.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. 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 under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

A UV Index reading of 6 to 7 represents a high health hazard from unprotected exposure to Sun's UV rays for the ordinary person.Note: In July, an average UV index of 7 transforms into the following instructions:
Prevent overexposure. Protection from the sun's harmful effects is needed. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun.
