Weather in July
Temperature
Columbia reaches its highest average temperatures in July, measuring 82.9°F (28.3°C) at the peak and 64.4°F (18°C) at the lowest.Heat index
Throughout July, the heat index is estimated at a tropical 91.4°F (33°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.The metrics for the heat index are tailored for both shady environments and light winds. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'feels like', integrates the air's temperature and its humidity to showcase the felt temperature by people. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
