A slight uplift of average high-temperatures is noted in May, with temperatures adjusting from 75.2°F (24°C) in April to a still warm 83.5°F (28.6°C). Swartz's nighttime temperature in May drops to an average of 64.9°F (18.3°C).Heat index
May's heat index is estimated at a hot 91.4°F (33°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.Note that heat index values are valued for light wind and location in the shade. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. 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.
