Live PET Data
Use the form below by selecting a weather station and date range to view the daily rainfall and potential evapotranspiration (PET) data. Not all the weather stations record PET, if you select a weather station that does not then the PET data from the nearest weather station that does record it will be used. The weather stations use the Penman/Monteith method to calculate PET.
You can see where the weather stations are positioned with the map below.
