S4C staff have been looking at alternative avenues to reschedule Sioe Nadolig Cyw in St Asaph and Caernarfon but because of the weather and heavy conditions over the weekend it has been impossible to do so.
S4C again apologises for the disappointment caused.
A television version of the stage production will be broadcast on S4C on Christmas Eve at 08:10 and again on Christmas Day at 12:15.
