Weather in May
Temperature
With the onset of May, the average high-temperature subtly transitions from a pleasant 73.2°F (22.9°C) in April to a warm 81.3°F (27.4°C). During May, Chattanooga witnesses a consistent average low-temperature of 61.2°F (16.2°C).Heat index
In May, the average heat index is evaluated at 84.2°F (29°C). If activity and exposure persist, they could induce fatigue, leading to possible heat cramps.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'feels like', represents the fusion of temperature and moisture in the air to suggest how warm it feels. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
