I have a black walnut and a couple of English walnuts. The
black walnut loses its leaves early, starting about this time of
year. The English walnuts lose their leaves late, usually in late
October or early November. (This is in Michigan.)

It sounds like your tree is stressed. Is it getting the right amount
of water? Too much is as bad as too little, and the symptoms
can look the same (yellow and then drying leaves). Your picture
also looks as if the leaves are spotty, which might be a fungal or
insect problem.
