Weather in July
Temperature
The arrival of July brings an average high-temperature of a still hot 91.2°F (32.9°C), closely following the temperature pattern of June. During July, Columbia experiences a consistent low-temperature average of 72.3°F (22.4°C).Heat index
For most parts of July, the heat index is computed to be a life-threatening hot 114.8°F (46°C). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.Keep in mind the heat index values are meant for areas in shade and with light wind. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. 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. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

A UV Index value of 6 to 7 symbolizes a high threat to health from exposure to the Sun's UV radiation for the ordinary person.Note: In July, the average maximum UV index of 7 translates into the following recommendations:
Avoid overexposure. Fair-skinned individuals can burn in under 20 minutes. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
