This post summarizes the July weather in Boston, with tips on what to wear, as well as things to do.
As local tour guides, we know that July is one of the best times for walking tours, because there's usually a lot of great, sunny weather.
And I am not just a tour guide. I'm also a retired meteorologist who has found a new way to put my experiences to work.
