ETo Finder

Irrigation professionals using the WaterSense Landscape Water Budget Tool may use the ETo Finder to determine peak month local evapotranspiration values (ETo) in inches/month.

Data presented in the ETo Finder come directly from the World Water and Climate Atlas, a project of the International Water Management Institute (IWMI). EPA would like to thank IWMI for the use of this data.
