Zion at a glance
Heating and cooling climate
NOAA's 1991–2020 climate normals for the CHICAGO WAUKEGAN RGNL AP, IL station show about 6,688 heating degree days and 626 cooling degree days in a typical year, with about 132 nights at or below freezing and 9 days reaching 90°F or more. Heating demand is far larger than cooling demand here, so the furnace, boiler or heat pump carries most of the load and a breakdown in a cold snap is the most pressing kind of call.
