Weather in May
Temperature
In Louisville, the onset of May comes with a modest high-temperature shift, transitioning from April's 77°F (25°C) to a still moderately hot 83.8°F (28.8°C). Louisville, during the month of May, experiences an average low-temperature of 63.7°F (17.6°C).Heat index
May's average heat index is estimated at a hot 89.6°F (32°C). Continuous activity in exposure could lead to a feeling of fatigue and heat cramps.Understand that the heat index values take into account shaded locations and mild winds. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
