Weather in May
Temperature
With the onset of May, the average high-temperature subtly transitions from a pleasant 73°F (22.8°C) in April to a moderately hot 80.6°F (27°C). In May, Merit's temperature tends to fall to an average low of 63.3°F (17.4°C) during the night.Heat index
In May, the heat index is computed to be 84.2°F (29°C). Long-standing exposure coupled with ongoing activity could result in exhaustion, possibly causing heat cramps.Note that heat index values are valued for light wind and location in the shade. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', unifies temperature and humidity readings to offer a comprehensive feel of warmth. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
