Weather in May

May, the last month of the spring in Mount Pleasant, is another warm month, with an average temperature ranging between max 85.6°F (29.8°C) and min 64.9°F (18.3°C).

Temperature

May's arrival brings a modest temperature shift, moving from 78.8°F (26°C) in April to a still moderately hot 85.6°F (29.8°C). Mount Pleasant encounters an average low-temperature of 64.9°F (18.3°C) during May nights.

Heat index

The heat index value for May is evaluated at a very hot 95°F (35°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.
It is emphasized that the heat index's values are meant for shaded zones with mild winds. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a single figure representing how weather conditions feel when combining temperature and humidity. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
