Weather in June
Temperature
Mattoon's transition into June is marked by a minor temperature shift, moving from 75.6°F (24.2°C) in May to a still moderately hot 83.8°F (28.8°C). Throughout the month of June, Mattoon reports a steady low-temperature average of 66°F (18.9°C).Heat index
In June, the average heat index is computed to be a hot 93.2°F (34°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.Heat index values are typically calculated for conditions of shade and a light breeze. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', shows a temperature sensation when both heat and moisture conditions are combined. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
