Decatur, Illinois, faces relatively low natural disaster and climate risks overall. The area's climate is characterized by moderate hardiness, average precipitation levels, and mild temperatures, with relatively high humidity. While the risk of hurricanes, tsunamis, and wildfires is very low, the area is prone to occasional thunderstorms and flooding due to its proximity to water bodies such as Lake Decatur.

Past flooding incidents in the area, such as those caused by heavy rainfall or snowmelt, serve as reminders of the importance of having emergency plans in place.
