51% wool/25% polyester/24% viscose suit in summer?

Hi! I am looking at a suit that is like this and wondering about it being worn in the summer (Chicago in mid-June, it could be anywhere between 75-90 degrees as the weather varys a lot but I’d guess it’ll be around 80 outside). Please let me know your thoughts, thanks in advance! I posted in the comments a picture of the one I’m looking at specifically.
