Weather in May
Temperature
With the transition into May, Macclenny notes an average high-temperature of a tropical 86.4°F (30.2°C), closely resembling April. During the month of May, the temperature falls to an average of 66.4°F (19.1°C).Heat index
In May, the heat index is calculated to be a sweltering 96.8°F (36°C). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. 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.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
