Hot, and windy, weather can cause a much faster loss of soil moisture which can require more than the 1 inch of water each week. One of the reasons why one cannot rigidly follow suggestions from distant places. Just how much water your lawn requires and when depends on the weather you are experiencing, the soil the lawn is growing in, and the species of grass. If the soil is a good healthy soil with adequate amounts of organic matter and is able to hold moisture well the lawn will need less water than one with sand and little organic matter that cannot hold much moisture.

There are no hard and fast rules about watering lawns, each one may be different.
