Growing up in Newington, Belfast, Hale started off playing his youth football with local club Crusaders.[2] It was there that he caught the eye and earned a move to England with Birmingham City. During this time, his brother Rory was playing at his side's city rivals, Aston Villa, which made the homesickness he suffered a little easier with both living in Birmingham.[2]
He scored an incredible 28 goals in 23 games for Birmingham City U21 side in his first season at the club, before moving up to the Birmingham City U23 side, where he scored 4 goals in 16 appearances.[3]

Derry lost the first leg 2–0 at home, leaving them with an uphill battle to go through in the second leg.[9] After an early goal from Ally Roy, Derry performed well and after conceding a first half equaliser, Hale scored the winner in the 75th minute but it wasn't enough despite a late Derry push as they were knocked out 3–2 on aggregate.[10] The 16 September 2018 saw Hale win the first trophy of his senior career when he scored in a 3–1 win over Cobh Ramblers as Derry City won the League of Ireland Cup for the record 11th time.[11] Hale ended the season, with 12 goals in 40 appearances in his first season in senior football.[12] He returned to Birmingham City at the end of his loan spell.[13]
