Weather in May
Temperature
The shift into May records an average high-temperature of a still hot 93.6°F (34.2°C), subtly varied from April's 90°F (32.2°C). Sullivan City's nighttime temperature in May falls to an average of 73°F (22.8°C).Heat index
The heat index for May is evaluated at a burning hot 113°F (45°C). Take caution: Heat exhaustion and heat cramps are probable. Heatstroke may be imminent with ongoing effort.Note that heat index values are valued for light wind and location in the shade. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', is an estimation of the warmth sensation when considering humidity levels. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are primarily vital for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
