Following the demise of the Welsh National League structure in 1930, senior clubs in the area demanded to a strong and competitive league. Football in North Wales had begun to decline and the intention was that this league would replicate the old Combination and provide a strong competition for clubs in north Wales and the borders.

The early discussions between officials of the Welsh League and Cheshire League to develop a cross-border competition were secretive. The proposals that emerged were put to a meeting of clubs at the Albion Hotel, Chester on the 5th of July 1930 and duly accepted. Nineteen clubs were given permission to apply, but with no guarantee of acceptance as other clubs were waiting to apply for membership of what was envisaged as initially an 18 club League. As it turned out the following clubs were accepted into membership - Buckley, Ellesmere Port Town, Bangor, Caernarvon Athletic, Flint Town, Blaenau Festiniog, Holywell Town, Llandudno, Mold Town, New Brighton Res, Rhyl Athletic, Wrexham Reserves and Colwyn Bay. Three clubs, namely Stockport County, Shell-Mex and Northern Nomads, who had originally intended to participate resigned for various reasons and Blaenau Festiniog resigned on financial grounds before the season started. Buckley, Holywell, Flint and Mold also resigned with only Llanfairfechan and Holyhead Town stepping in to make a less impressive ten-club league. Lt Col. J Llewelyn Williams of Holywell became president with H R Williams of Bangor took on the secretary’s role. In November 1930. Caernarvon Athletic went into liquidation and their fixtures were taken-over by Bethesda Victoria. During the 1930-31 season clubs played each other twice home and away but this was not a financial success.

As the Combination had not drawn in clubs from Cheshire, FAW secretary Ted Robbins, suggested at a meeting in Bangor on 13 July 1931, that an east and west league should be formed in North Wales with Llandudno or Colwyn Bay as the dividing line. It was decided to call the new league the Welsh Combination. Five clubs in the North Wales Football Combination then decided to resign and join the new league. The new structure covered an area from Llandudno to Holyhead; Portmadoc, Pwllheli and Bl Ffestiniog. By the following week no clubs were left in the original league and it was wound up.

For the 1931-32 season, champions Colwyn Bay, Rhyl Athletic, New Brighton, and Ellesmere Port all resigned. New members were elected: Blaenau Festiniog, Penmaenmawr FC, Pwllheli and Conway FC. At the end of the season only Penmaenmawr dropped out but the league increased in size with the addition of Llanrwst Town and Caernarvon Athletic.

At the AGM at the end of the third season, a change of name to the North Wales Coast League was proposed and accepted, thus closing another chapter in the history of league football in North Wales.
