Weir competed at small competitions and qualifying events in order to be eligible to compete at the 2013 U.S. Nationals. He competed at the 2012 Finlandia Trophy, attempting a quadruple jump in both his short program and free skate for the first time, and coming in fourth place overall. In his short program, he stumbled on his opening quadruple toe jump, which was downgraded, but successfully completed his triple Axel and triple lutz-double toe combination, and earned level-four scores for his flying camel spin. He was in fourth place after the short program, earning 69.03 points. He later told reporters that he was nervous, that his legs felt stiff, and that the competition was the hardest thing he had done in his career. He also had boot problems to overcome, but felt that he had done well. He came in sixth place in the free skate, earning 132.39 points; he earned 201.42 points overall.
