Weather in May

May, the last month of the spring in Picayune, is also a moderately hot month, with an average temperature varying between 66.6°F (19.2°C) and 85.3°F (29.6°C).

Temperature

The start of May brings a subtle rise in the average high-temperature, moving from a warm 78.6°F (25.9°C) in April to a still moderately hot 85.3°F (29.6°C). Throughout May, the temperature falls to an average low of 66.6°F (19.2°C).

Heat index

May's heat index is appraised at a very hot 95°F (35°C). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.
Remember that heat index calculations are made for conditions in the shade with light wind. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
