Indiana Dunes in January: what the park service says
January at Indiana Dunes brings shelf ice along Lake Michigan, and the park service is blunt about it: walking on shelf ice is extremely hazardous, people falling through hidden holes can disappear from view, and death is likely. Ponds and creeks are not monitored for safe ice either. Winter highs usually sit in the low to mid-30s°F, with lows in the low 20s.
