Weather in May
Temperature
Observing a slight rise in May, the average high-temperature shifts from April's 73.9°F (23.3°C) to a still moderately hot 81.9°F (27.7°C). Keyno, during May nights, observes an average temperature of 60.4°F (15.8°C).Heat index
During May, the heat index is computed to be a tropical 86°F (30°C). Exhaustion might be the outcome of enduring exposure and continuous activity, with a risk of heat cramps.Records show heat index calculations are tailored for shaded regions and mild winds. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a composite of temperature and humidity figures to convey how warm it feels. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
