Weather in May
Temperature
The start of May brings a subtle rise in the average high-temperature, moving from 78.8°F (26°C) in April to a still warm 85.6°F (29.8°C). In Mount Pleasant, an average nighttime temperature of 64.9°F (18.3°C) is expected during May.Heat index
May's mean heat index is appraised at a very hot 95°F (35°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.Metrics for the heat index primarily focus on shaded spots and light wind conditions. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Ward off overexposure. Defence against solar harm is crucial.
