Weather in May
Temperature
In Round O, stepping into May brings a gentle temperature nudge, moving slightly up from April's moderately hot 75.7°F (24.3°C) to a still warm 82.8°F (28.2°C). During the nights in May, Round O experiences a consistent average temperature of 64.2°F (17.9°C).Heat index
May's mean heat index is evaluated at a tropical 89.6°F (32°C). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.Understanding the heat index involves considering values for shaded locales with light wind. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. 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 meaningful for babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
