Weather in May
Temperature
As April transitions into May, Picayune notices a gentle rise in the average high-temperature, transitioning from 78.6°F (25.9°C) to a still moderately hot 85.3°F (29.6°C). During the month of May, the nighttime temperature falls to an average of 66.6°F (19.2°C).Heat index
The average heat index in May is calculated to be a torrid 95°F (35°C). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.Heat index details are generally centered around shaded locations and a mild breeze. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

Sustain precautions and conform to sun safety norms. Preventing sunburn is necessary. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Counter UV radiation's ill effects with clothing designed for sun safety and UV-resistant eyewear.
