Irrigation in the landscape
Native plant root systems

Only water the lawn once a week using the soaker cycle. Large heads should water about a total of 45 minutes and smaller heads about 30 minutes. With that time, you make two watering cycles with each one being half the amount of time. So, the first round goes for 20 minutes and the second for 25 minutes for the large heads and then the same math for the small heads.
These times are just averages and aren’t completely accurate since you would need to know how many gallons per hour your heads are spraying. But these numbers are fairly close.
If you have or are planning to plant native plants, then you will need little to no water once they are established. The picture with the root zones for our natives isn’t fake and helps us understand how our natives are able to survive in our climate. https://www.usbg.gov/exposed-secret-life-roots
Don’t’ forget to keep a birdbath or a pan with some water for the smaller critters in the yard. Put some rocks in the bottom of the saucer tall enough that the butterflies, small birds and bees can rest on them while they get a drink.
If you’re worried about being outside with the heat then you can take advantage of house plants or succulents. Neither are as scary as people think and for the most part you just water them when they get dry. With a simple pot you can get pretty creative with different styles, colors and heights. For example, a tall plant for height and then maybe something that will trail or hang over the sides. Let your imagination take over when it comes to design.
