Weather in May
Temperature
May's arrival is noted with a slight increase in the average high-temperature, moving from 78.3°F (25.7°C) in April to a still warm 83.8°F (28.8°C). An average low-temperature of 65.8°F (18.8°C) is noted during the nights in May in Marion.Heat index
For May, the heat index is computed to be a hot 93.2°F (34°C). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.Keep in mind the heat index values are meant for areas in shade and with light wind. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is the result of factoring in humidity to the air temperature, indicating perceived warmth. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
