Weekly Watering Schedule

Hero Weekly Watering Schedule

Properly programming your irrigation controller and making regular adjustments to the schedule helps ensure you are watering your garden as efficiently as possible.

The Weekly Watering Schedule provides a recommended irrigation schedule each week, based on irrigation equipment, plant type, and weather conditions. It is not a forecast and may need adjusting due to hot or cold weather, and other factors. The schedule is updated every Friday during the irrigation season. 

Please note that the current schedule is adjusted to reflect Marin Water's current 2-day per week watering restrictions and ongoing drought conditions in California.

How To Use The Weekly Watering Schedule

Detailed information is provided in the Weekly Watering Schedule User Guide.

Option 1: Program your controller for June/July and use the watering index below to adjust your controller using the seasonal adjustment feature.

Option 2: Use the schedules published below to adjust your controller through the irrigation season.

  • Select either Inland/Upland Zones or Coastal Zones below for the climate zone where you're located.
  • Look up the run times for your plant type and irrigation type.
  • The weekly run time is often split into multiple, shorter run times to help reduce runoff. Allow 30 to 60 minutes between run times to allow water to soak into the soil.
