Weather in May
Temperature
May brings a slight increase in the average high-temperature, progressing from an agreeable 73°F (22.8°C) in April to a moderately hot 81°F (27.2°C). Harrisburg observes an average nighttime temperature of 60.1°F (15.6°C) during May.Heat index
May's mean heat index is evaluated at a hot 86°F (30°C). Ongoing activity coupled with exposure often results in weariness and could induce heat cramps.Remember that heat index calculations are made for conditions in the shade with light wind. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. 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.
