My girlfriends and I are going to Chicago September 12-14 and I was curious what the temperatures are like then. I looked up the averages on weather.com and it say mid 70's during the day and 50's at night. We are staying on Michigan Avenue and I know it windy down there. I have been in October before and we had to wear heavy coats because it was really chilly, but I am curious about the dates we are going.
Is it warm enough to where a cocktail dress and not freeze to death then at night time and what it is like during the day?
Your opinions are greatly appreciated!!!
