Newly-seeded lawns will require a specific watering schedule. Seed is unique in that it requires just enough water to keep it moist while germinating. After germination, water consistently to support root and blade growth, but avoid overwatering as it can wash seeds away.
Weather will definitely impact the watering schedule. Rain, extreme temperature and wind need to be taken into consideration, and the schedule needs to be adjusted properly.
Be sure to check with local ordinances for watering restrictions.
