The daily July to June water balance at Winchmore, Canterbury.
Figures showing daily water balance at over 100 climate stations around New Zealand are available on ClimateExplorer. The model that generates the figures makes some broad assumptions. The available water capacity, for example, is taken to be 150 mm, which is about right for the pasture root zone of an average silt loam soil. The model works best for level paddocks under pasture.
