Weithiau mae’n rhaid cau ysgolion am resymau fel gweithredu diwydiannol neu ddiwrnodau HMS. Caiff y dudalen hon ei diweddaru’n uniongyrchol gan ysgolion i roi gwybod ymlaen llaw am unrhyw ysgolion a gaiff eu cau.
I gael gwybodaeth am ysgolion a gaiff eu cau yn ddirybudd, er enghraifft pan fo tywydd difrifol, gweler y dudalen cau ysgolion.
