Weather in May
Temperature
The onset of May marks a slight increase in the average high-temperature, moving from a moderately hot 76.6°F (24.8°C) in April to a still warm 82.9°F (28.3°C). Throughout the month of May, Harahan Junction expects an average low of 70.9°F (21.6°C).Heat index
The heat index for May is estimated at a tropical 89.6°F (32°C). If one persists in activity during exposure, it could induce weariness and subsequently, heat cramps.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. 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 largely 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.
