Weather in May
Temperature
May introduces a marginal temperature uplift, with average high-temperatures adjusting from April's 78.4°F (25.8°C) to a still moderately hot 85.6°F (29.8°C). During May, Port Allen experiences an average low-temperature of 65.7°F (18.7°C) at night.Heat index
In May, the average heat index is computed to be a sweltering 96.8°F (36°C). Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.Heat index evaluations are typically in the context of light winds and shaded environments. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a single figure representing how weather conditions feel when combining temperature and humidity. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. 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 hold particular importance for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

In May, the average relative humidity is 76%.Rainfall
In Port Allen, in May, it is raining for 14.7 days, with typically 2.83" (72mm) of accumulated precipitation. Throughout the year, there are 177.1 rainfall days, and 36.1" (917mm) of precipitation is accumulated.Snowfall

Sunshine
In May, the average sunshine is 9.7h.UV index
May through August, with an average maximum UV index of 7, are months with the highest UV index. A UV Index value of 6 to 7 symbolizes a high health vulnerability from unsafe exposure to UV radiation for average individuals.Note: In May, the UV index of 7 transforms into the following advice:
Refrain from overexposure. Fair-skinned individuals could burn in under 20 minutes. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. Boost your sun resistance with garments that are densely woven yet spacious.
