Weather in May
Temperature
A soft shift in the average high-temperature is noticeable in May, transitioning from 76.6°F (24.8°C) in April to a still warm 82.6°F (28.1°C). Sapelo Island's nighttime temperature during May is consistently averaged at a refreshing 67.1°F (19.5°C).Heat index
The heat index value during May is computed to be a tropical 87.8°F (31°C). Persistent activity under exposure might lead to a feeling of weariness, with subsequent heat cramps.It is emphasized that the heat index's values are meant for shaded zones with mild winds. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', is achieved by amalgamating air temperature with the relative humidity readings. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
