The purpose of this study is to analyse the accuracy of weather forecasts of temperature. precipitation probability, and sky condition and to evaluate the applicability of weather forecasts for the estimation of potential evapotranspiration for irrigation scheduling. Five weather stations were selected to compare forecasted and measured climatical data. The error between forecasted and measured temperature was calculated and discussed. The accuracy of temperature forecast using relative frequency of the error was calculated. The temperature forecasting showed considerably high accuracy. Average sunshine hours for forecasted sky conditions were calculated and showed resonable quality. From the reliability graphs. the forecasting precipitation probability was reliable. Potential evapotranspirations were calculated and compared using forecasted and measured temperatures. The weather forecast is considered usable for irrigation scheduling.
