I think it might get too cold for it over winter where you live, and I wouldn't try to grow it outside there at all unless your winter nights do not go below 40 Fahr. It should be out til just before the first frost though.

It should be protected from frost and cold draughts. Cold winds turn the leaves brown at the edges and then kill them but the roots of a mature bay are hardy. Feed and water sparingly during winter. Can be grown successfully in pots, and should be brought indoors if temperatures outside drop below 15°C.
