Evapotranspiration (ET) is used to calculate your outdoor water budget and is an estimate of the water lost through the natural processes of evaporation and plant transpiration (sometimes called plant sweat). This interactive map provides reference evapotranspiration (ET0) for each of the District’s microzones and shows the variation across the District’s service area.
Feel free to zoom in, zoom out and click around to see the cumulative ET0 in inches for a time range that you select. You can see the amount of ET0 estimated for your yard last Saturday, or for the entire last month. This is very helpful if you are trying to optimize your watering schedule and irrigation system to stay within your budget.
