Weather in May
Temperature
With the onset of May, Edisto Island's average high-temperature sees a modest rise, moving from April's 74.3°F (23.5°C) to a still moderately hot 81.1°F (27.3°C). Nighttime temperatures hover around an average low of 66.7°F (19.3°C) in May.Heat index

Uninterrupted activity during exposure could lead to a sense of exhaustion, possibly causing heat cramps.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', determines the feeling of heat when you account for the relative humidity. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are particularly important for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
