Weather in May
Temperature
The coming of May brings a minor shift in Hardeeville's weather, with average high-temperatures adjusting from April's 75.7°F (24.3°C) to a still warm 82°F (27.8°C). Throughout May, the average low-temperature dips to an enjoyable 65.3°F (18.5°C).Heat index
The heat index in May is calculated to be a tropical 87.8°F (31°C). If exposure and ongoing activity persist, they might induce a state of tiredness and heat cramps.Metrics for the heat index primarily focus on shaded spots and light wind conditions. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
