Sprinkler spraying water on a lawn

How Much Water Your Sunny Lawn Should Get
On average, your lawn should get the recommended 1 to 1.5 inches of moisture a week, but the sunny areas of your lawn should get a little extra moisture.
The sun will heat up the soil and evaporate any water in it, drying out the sunny areas of the lawn. Dry soil needs to be watered more often to keep the yard thriving.
Although the air temperature is the same in the shady areas and sunny areas, the solar radiation further heats the portions of the yard that don’t have shade from trees.
Sunny areas may need up to 1 more inch of water than the shaded areas of your lawn. However, you should adjust this amount based on the weather and the time of year.
Cloudy weather will provide extra protection for your lawn and will allow you to water your lawn less. The same goes for the cooler months of spring and autumn.
You could lose anywhere from 25% to 50% of the sprinkler’s water through evaporation at midday. Try to water before 10 a.m., or between 4 p.m. and 6 p.m. to avoid evaporation.
