Weather in May
Temperature
A gentle upsurge in temperatures occurs in Beaufort as April gives way to May, with average highs shifting from a warm 74.7°F (23.7°C) to a still moderately hot 81.1°F (27.3°C). In Beaufort, the average temperature during the nights of May drops to a comfortable 66.9°F (19.4°C).Heat index
The heat index in May is appraised at a hot 86°F (30°C). Unrelenting activity during exposure could cause fatigue and potentially lead to heat cramps.In terms of the heat index, values are set with light wind and shade conditions in mind. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. 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.

Prevent overexposure. Protection from the sun's harmful effects is needed. Limit your exposure to the sun's UV radiation, which is strongest between 10 a.m. and 4 p.m., and note that parasols or canopies may not provide full sun protection. To cut down UV radiation exposure by about half, sport a wide-brim hat.
