Seattle summers are becoming hotter and drier—and your lawn feels it. With water restrictions and unpredictable rainfall, many homeowners ask:
“How much should I water my lawn during the summer?”
Here’s what you need to know to keep your lawn green and healthy through the heat.
Seattle Summer Lawn Watering Guidelines
-
Water Deeply, Not Daily:
Water your lawn 2–3 times per week, not every day. Each session should deliver about ½ inch of water, soaking the top 6 inches of soil. This encourages deep root growth and drought tolerance. -
Early Morning is Best:
Water between 4 AM and 8 AM to reduce evaporation and fungal risk. Avoid watering during peak afternoon heat or late evening. -
Use the “Tuna Can Test”:
Place a shallow container on your lawn during watering. When it fills to ½ inch, you’ve watered enough. -
Watch for Signs of Stress:
If your lawn turns bluish-gray or footprints remain visible after walking, it’s time to water. -
Dry Patches?
These may be caused by poor sprinkler coverage or compacted soil. Consider professional solutions like soil wetting agents and aeration to improve water absorption.
Why Lawn Watering Alone Isn’t Enough
Even with the right watering routine, many Seattle lawns struggle in summer due to:
-
Compacted soils that repel water
-
Shallow root zones from years of stress
-
Inefficient irrigation systems
