The 2012–13 season was very successful for Scarborough Athletic which culminated with the club being crowned Champions of The Northern Counties East League Premier Division. Athletic made a good start to the season losing only one of their opening 14 league games. By the end of September they were sitting in second place, a point behind the leaders in a tightly contested table. Athletic's fine form in the league continued to the end of the year and with the help of a 2–1 Boxing Day victory over their landlords Bridlington Town, they entered 2013 as league leaders. The consistently good run of results continued into the latter half of the season and Athletic eventually went on to record a 26-game unbeaten league run that consisted of 20 wins and six draws and on 30 March a Bridlington Town vs Scarborough Athletic meeting attracted a crowd of 1,569, a new club and divisional record, eclipsing the previous best set by the same fixture three seasons previously. Despite the great form, Athletic were still not sure of promotion until the penultimate week of the season due to the good form of second place Brighouse Town. On 13 April 2013 Athletic visited Brighouse Town for a first vs second place clash which they won 2–0, a result that put them 9 points clear at the top of the table with just two games remaining (Brighouse had four games left to play). The following week Athletic beat Retford United 2–0 at home whilst Brighouse Town could only draw their game and, amidst great scenes of celebration, the league title was Scarborough Athletic's.
