Weather in May
Temperature
In May, the meteorological conditions subtly change with the average high-temperature edging from 74.8°F (23.8°C) in April to a still moderately hot 80.8°F (27.1°C). During May, Surfside Beach's nighttime temperatures demonstrate a subtle cooling from daytime highs, stabilizing at a pleasant 73.2°F (22.9°C).Heat index
The heat index in May is evaluated at a hot 86°F (30°C). Fatigue might occur with continuous exposure and activity, potentially causing heat cramps.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
