Re: What to Wear/Fashion a & September Weather in Rome/Tuscany. Jul 29, 2005, 9:53 PM. Susan, hubby and I are going to Rome and Tuscany the same time you are. We will be a week in Tuscany and 4 days in Rome on the way back. Thanks for getting a reply to your question as I asked this also and didn't get a reply. I was wondering what the weather would be like and what to pack in mid-September.
