Weather in July
Temperature
Columbia witnesses the warmest weather in July, with temperatures averaging a high of 86°F (30°C) and a low of 66.6°F (19.2°C).Heat index
July's mean heat index is computed to be a very hot 98.6°F (37°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical to babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.

Sunshine
In July, the average sunshine is 10.1h.UV index
May through August, with an average maximum UV index of 6, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health risk from unprotected exposure to Sun's UV rays for the ordinary person.Note: In July, the UV index of 6 transforms into the following advice:
Deflect overexposure. Sun protection is a necessity. Limit your exposure to the sun's UV radiation, which is strongest between 10 a.m. and 4 p.m., and note that parasols or canopies may not provide full sun protection. Always opt for UVA and UVB-resistant sunglasses on radiant days.
