The first month of the summer, June, is a moderately hot month in Chapin, Illinois, with an average temperature varying between 81.5°F (27.5°C) and 64.6°F (18.1°C).

Temperature

A gentle upsurge in temperatures occurs as May gives way to June, with average highs shifting from a pleasant 72.9°F (22.7°C) to a warm 81.5°F (27.5°C). Chapin's temperature lowers to a mean of 64.6°F (18.1°C) during the nights in June.

Heat index

In June, the heat index is calculated to be a tropical 87.8°F (31°C). Enduring exposure and unrelenting activity might cause a state of weariness, potentially leading to heat cramps.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'feels like', comes about by integrating the temperature readings with the humidity levels. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
