Weather in August
Temperature
Transitioning into August, Columbia experiences an average high-temperature of a still warm 83.1°F (28.4°C), marking a minor shift from the preceding month. Columbia undergoes a major shift from daytime highs, averaging a comfortable 61°F (16.1°C) during the night in August.Heat index
In August, the heat index is calculated to be a hot 86°F (30°C). If one persists in activity during exposure, it could induce weariness and subsequently, heat cramps.Consider that heat index readings are for situations in the shade and light wind. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
