Weather in June

June marks the doorstep to summer in Springfield. The offering of longer days and ample sunlight turns the city into a sun-soaked haven. With more sunshine hours of around 10.4 hours and highs of up to 81.1°F (27.3°C), it is a splendid time for summer activities. However, as humidity begins to rise, those unaccustomed to it might experience discomfort. A dip in the local lake or taking advantage of the city’s green canopy might serve as a retreat from the heat.

Temperature

In June, the average high-temperature marginally rises from a pleasant 72.9°F (22.7°C) in May to a moderately hot 81.1°F (27.3°C). In the month of June, an average of 64.6°F (18.1°C) marks the low-temperature.

Heat index

During June, the heat index is appraised at a tropical 86°F (30°C). Long-standing exposure coupled with ongoing activity could result in exhaustion, possibly causing heat cramps.
The heat index's values are generally associated with conditions in shade and light breezes. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
