If watering your lawn in the early morning hours is not possible, the next best time of day to water your lawn is in the evening after the sun has already cooled down significantly. This will allow the water to soak into the topsoil properly.
Nonetheless, should October turn dry and remain warm, lawn grasses will likely benefit from an additional watering or two before shutting down for the winter. In general, it's a good practice to not have lawn grasses go into winter conditions severely stressed due to lack of water.
