Weather & Attire

Weather
Autumn is a pleasant and invigorating time of year in Chicago. Afternoon temperatures frequently reach between 65°-75°F in October, while the nighttime lows usually range from 50°-55°F. Precipitation is relatively light with average rainfall in October just over 2.5 inches.

Attire
Appropriate attire is "business casual" for all business sessions and related events. A sweater or jacket is recommended for the Closing Networking Celebration at the House of Blues and also for inside the meeting rooms, as these temperatures tend to vary.
