One of the most open for many years, particularly with Caernarfon Town , Oswestry Town , Porthmadog and Welshpool Town having won four of the previous five titles.
For the fourth consecutive season, the Cymru Alliance did not receive a club on relegation from the Welsh Premier, but did gain three new members. Bala Town (Welsh National League (Wrexham Area) champions), Llandyrnog United (Welsh Alliance runners-up) and Penrhyncoch (Mid Wales League winners), replacing Amlwch Town who returned to the Welsh Alliance after two years at the higher level.
At the halfway stage, Llangefni Town, who had finished runners-up in 2001/02 (and as Llangefni-Glantraeth the following season) held a narrow advantage over Buckley Town and league newcomers Bala Town and Llandyrnog United.
Glantraeth, positioned just behind the top four, were well-placed to make a title challenge in the second half of the campaign. Whilst the Anglesey county town club continued to hold the lead, as the season moved into spring, Llangefni Town seemed to become nervous as they approached the finishing line. They dropped enough points, during the final weeks of the season, to allow a consistent Buckley Town, who suffered only three defeats throughout the season, to claim the championship.
The Lon Talwrn club suffered such a dip in form that Glantraeth sneaked above them, to claim runners-up position, and deprive their arch rivals of any chance of obtaining promotion.
The three newcomers all performed creditably, as Llandyrnog United finished sixth. Whilst Bala Town, who ended two places higher, defeated Penrhyncoch in the League Cup final.
