Weather in May

May's arrival signals a subtle increase in average high-temperatures, moving from April's 74.3°F (23.5°C) to a still moderately hot 81.1°F (27.3°C). Vance records a mean low-temperature of 63.1°F (17.3°C) in May.Heat index
During May, the heat index is appraised at a tropical 86°F (30°C). One might feel worn out with persistent exposure and activity, resulting in heat cramps.Data suggests that the heat index is set for environments in shade and with a light wind. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', arises from combining readings of air temperature and relative moisture content. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
