Weather in May
Temperature
As Vivian, Louisiana, welcomes May, the average high-temperature sees a modest rise, transitioning from 75.9°F (24.4°C) in April to a still warm 84°F (28.9°C). In May, Vivian experiences a temperature dip to an average of 63.1°F (17.3°C) at night.Heat index
During May, the heat index is computed to be a hot 91.4°F (33°C). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.The standards for the heat index are set for locations in shade and under light breezes. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
