The regular season began in late October 2015 and was completed by May 2016 . It used the traditional round-robin format with each team playing two full rounds of games home and away . Before the season was finished Castlebar Celtic withdrew because they were unable to field a team . Celtic had played nine games , losing eight and winning just one . All their results were subsequently expunged . During the course of the regular season Celtic had suffered two heavy defeats . On 10 October 2015 they lost 9 – 1 at home to Shelbourne Ladies . Then on 2 January 2016 they lost 17 – 1 to Wexford Youths . As a result of storms and floods , the season saw several games called off . This resulted in a backlog of games during the final run in . Some of these games were played midweek . In the final week Wexford Youths travelled to Galway W.F.C. on Sunday , 8 May knowing a victory would secure them the league title . However Youths dropped their first league points away from home and could only manage a 1 – 1 draw . Youths had a second chance to clinch the title when they played Shelbourne Ladies at Tolka Park on Wednesday , 11 May . However Shelbourne Ladies won 3 – 1 and as result finished level on points with Youths . This meant the title would be decided by a play-off for the first time . Before the play-off Shelbourne Ladies defeated UCD Waves in the WNL Cup final on Sunday , 15 May . The play-off took place on Sunday , 22 May at Tallaght Stadium . It proved third time lucky for Wexford Youths as they finally secured the title with a 2 – 1 win
