Weather in July
Temperature
In Columbia, the average temperatures in July are the highest, with a peak at 82.4°F (28°C) and a low of 61.9°F (16.6°C).Heat index
During July, the heat index is evaluated at a tropical 89.6°F (32°C). When exposure and activity are sustained, they could induce fatigue, with a chance of heat cramps.Understanding the heat index involves considering values for shaded locales with light wind. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', joins air temperature with relative humidity to produce a temperature perception for humans. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
