Weather in May
Temperature
The shift from April to May is marked by a slight increase in the average high-temperature, moving from 77.7°F (25.4°C) to a still warm 84.7°F (29.3°C). An average low-temperature of 63.7°F (17.6°C) marks the nights in Belleville throughout May.Heat index
The average heat index in May is evaluated at a hot 93.2°F (34°C). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.Consider that heat index readings are for situations in the shade and light wind. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. 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. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
