The following links are to climate summaries for area cities. Only the summaries for Peoria, Springfield, and Lincoln are considered "official", meaning they are the station of record for their respective locations. The other summaries are "supplemental", meaning another location in the area is the official climate station for the city.

Climate data for other cities is available at https://www.weather.gov/wrh/climate?wfo=ilx
