•Series generated by SSA and DWT contain information of ‘future’ values.•Hybrid models generate false ‘low’ prediction error and cause large errors in test.•In literature the usage of SSA and DWT in building hybrid models is incorrect. In hydrological time series prediction, singular spectrum analys...
