Weather in May
Temperature
The shift into May is marked by a modest rise in the average high-temperature, moving from April's warm 74.3°F (23.5°C) to a still moderately hot 81.1°F (27.3°C). Barnwell records a consistent low-temperature of 63.7°F (17.6°C) during May nights.Heat index
May's mean heat index is estimated at a hot 86°F (30°C). If exposure and ongoing activity persist, they might induce a state of tiredness and heat cramps.Data suggests that the heat index is set for environments in shade and with a light wind. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', marries air temperature and humidity to produce a value illustrating perceived warmth. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
