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.
(If you simply must plant in hot weather, mulch the planting area with a light layer of peat moss or similar material to prevent the seed from drying out.) Where you live, and throughout much of the northern half of the U.S., early fall is the best time for sowing grass.
