Weather in May
Temperature
May's onset brings a subtle temperature rise, moving from 78.4°F (25.8°C) in April to a still moderately hot 85.3°F (29.6°C). An average low-temperature of 66.4°F (19.1°C) is expected in Merlin, Louisiana, during May.Heat index
In May, the heat index is appraised at a very hot 96.8°F (36°C). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.Factoring in the heat index, values are geared towards shaded areas with light breezes. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', measures the perceived warmth when incorporating the humidity present in the air. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. 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 hold great significance to children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
