- Evenings
- 8–12°C

National Weather Service Chicago O’Hare station normals cover 1991–2020. Mean daily maximum 70.5°F (21.4°C), minimum 50.6°F (10.3°C), monthly precipitation 4.49 inches (114.0 mm). Clothing bands convert to Celsius, round and expand by 2°C each way; these are outfit prompts, not forecast limits. Precipitation includes water-equivalent snow. Airport exposure differs from downtown streets, riverbanks and the lakefront. Check the forecast for your actual travel dates.
