Weather & conditions
Typical 31°F high / 16°F low
Cold, wind-scoured prairie winter. The compensations are real: frozen waterfalls at Starved Rock and wintering bald eagles along the Mississippi's locks and dams.
What to do in January
- Ice falls in Starved Rock's canyons
- Eagle-watching on the Mississippi
- Chicago's museums on the coldest days
Best-fit rigs: Motorhome · Truck or van
Know before you go
Sub-freezing stretches and lake-effect snow make winter RVing here a specialist pursuit; most campgrounds are closed.
Severe thunderstorms and tornadoes are possible May through July. Winter road conditions can deteriorate quickly.

January tips for Illinois
Nights dip to freezing or below: insulated water hose, tank protection or a winterized rig, and extra propane.
Carry traction boards and check chain requirements before any mountain route.
Plan shorter driving days — winter-pattern daylight is limited and campground offices close early.
