Weale was born in Troed-y-rhiw in Glamorgan and after playing youth football for Merthyr Tydfil he was signed by West Ham United in March 1925.
He made his Swindon Town debut on 17 September 1927 in a Third Division South match against Charlton Athletic (drawn 2–2).
A "fast, clever right winger", he made a promising start to his Southampton career, and scored a hat trick in a 4–0 victory over Notts County on Boxing Day, following this with goals in the next two matches.
He subsequently played for Newport County and Wrexham and then travelled to Belfast to join Glentoran, before finishing his career back in the lower leagues in England.
His younger brother, Tom, was also a professional footballer who had an unsuccessful trial with Southampton in 1929, before joining Swindon Town.
