Weather in May
Temperature
Lexington perceives a slight temperature ascent during May, with average high-temperatures adjusting from a moderately hot 73.6°F (23.1°C) in April to a still warm 80.8°F (27.1°C). Lexington cools down to an average low-temperature of 63°F (17.2°C) throughout the month of May.Heat index
The heat index for May is computed to be 84.2°F (29°C). Exhaustion becomes probable with enduring exposure and activity, potentially causing heat cramps.Heat index evaluations are typically in the context of light winds and shaded environments. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', arises from combining readings of air temperature and relative moisture content. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. 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 are particularly relevant to babies and toddlers. 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.
