Springfield Weather, When to Go and Climate Information

(Springfield, Illinois - IL, USA)

The humid continental climate of the Illinois capital simply put means cold winters and hot summers, which can feel very humid at times. Typical of the weather experienced by a mid-latitude city, Springfield sees heavy winter frosts and summer highs easily reaching 32°C / 90°F and rising even higher on occasion.

During the cold winter months, snow makes a regular appearance in Springfield, with snowy winter weather being very much the norm anytime from November to March. Occasional snow flurries in April, May and October are also not unheard of, but are always quite light and rarely settle.

The springtime climate in Springfield begins to make itself known in March, when the overnight frosts become less frequent and the daytime temperatures begin to reach double figures.

Seasonal Climate Variations / When to Go

By the time that April arrives, temperatures soon begin to reach 20°C / 68°F on the sunniest of days, climbing to a scorching 30°C / 86°F or more in July and August, when the weather is at its sunniest and hottest.

The hot summer climate can often feel rather humid, meaning that during the heat of the day, lunch in an air-conditioned restaurant is a good way to deal with the high temperatures. Later on, however, the balmy evenings lend themselves to exploring the city and enjoying the outdoor attractions, events and gatherings, or perhaps some al fresco dining with friends.

Climate extremes do occur all over Illinois and Springfield is no exception. Precipitation levels tend to be slightly raised from April to September, when heavy showers or even thunderstorms can come along, quite unexpectedly. While tornados are far from common in the city, they do occasionally wreak havoc and did cause much damage in 2006.
