Weather in May
Temperature
A minor escalation in the average high-temperature is seen in Greenville with the onset of May, moving from an agreeable 73°F (22.8°C) in April to a warm 81.9°F (27.7°C). Nightly temperatures drop to an average low of 65.1°F (18.4°C) in May.Heat index
May's mean heat index is computed to be a hot 86°F (30°C). If one endures exposure and continues to be active, it might result in tiredness and heat cramps.Evaluating the heat index requires understanding its values in the shade and with gentle winds. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
