Weather in June
Temperature
Wheaton's transition into June is marked by a rise in the average high-temperature, advancing from a moderately hot 75.6°F (24.2°C) in May to a hot 86°F (30°C). Wheaton cools down to an average low-temperature of 66.2°F (19°C) throughout the month of June.Heat index
In June, the heat index is estimated at a fiery hot 96.8°F (36°C). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.Research indicates the heat index considers values in shaded locales and with light winds. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. 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 extremely significant for babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
