Weather in May
Temperature
As Columbia welcomes May, the average high-temperature sees a modest rise, transitioning from a warm 77.5°F (25.3°C) in April to a still moderately hot 84°F (28.9°C). Columbia records an average low of 65.1°F (18.4°C) throughout the nights in May.Heat index
The average heat index in May is estimated at a tropical 89.6°F (32°C). If one endures exposure and continues to be active, it might result in tiredness and heat cramps.Know that the heat index computations account for shaded terrains and slight winds. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.

May through August, with an average maximum UV index of 7, are months with the highest UV index. A UV Index of 6 to 7 symbolizes a high health risk from exposure to the Sun's UV rays for the average person.Note: In May, a regular UV index of 7 translates into these guidelines:
Guard oneself from overexposure. Defence against sun injury is vital. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly.
