Again, when I was 13, I was left home *all* summer, and I was absolutely not allowed to leave the house or have friends over while home alone. I was fine. I had chores and reading. That was pre-internet! And we were in the 'burbs (nothing to walk to other than a playground).
As long as you have electricity and an internet connection, he'll probably spend some time messaging his friends. I would require chores to make sure he doesn't spend all of his time doing that.
But really, I don't think it's that long for a 13 year old to be home alone.
