Jimmy Suarez appeals his sentence of 24 months’ imprisonment, imposed upon revocation of his supervised release. He contends that his sentence, which was above the guideline range of 12 to 18 months, was substantively unreasonable because it was greater than necessary to serve the purposes of 18 U.S.C. § 3553(a).

We review a district court’s revocation of supervised release for an abuse of discretion and the sentence imposed upon revocation of supervised release for rea *872 sonableness. United States v. Velasquez Velasquez, 524 F.3d 1248, 1252 (11th Cir. 2008).

A sentence is substantively unreasonable if, considering the totality of the circumstances, the court weighed the § 3553(a) factors unreasonably and imposed a sentence that did not achieve the purposes of sentencing outlined in § 3553(a). United States v. Irey, 612 F.3d 1160, 1189 (11th Cir. 2010) (en bane), cert. denied, — U.S. -, 131 S.Ct. 1813, 179 L.Ed.2d 772 (2011). 1 The weighing of these factors is within the discretion of the district court, and we do not substitute our own judgment or reweigh those factors on appeal. United States v. Saac, 632 F.3d 1203, 1214-15 (11th Cir.), cert. denied, -U.S. -, 132 S.Ct. 139, 181 L.Ed.2d 58 (2011).

Here, the district court considered Suarez’s multiple violations of the conditions of supervised release. Suarez admitted to numerous substantial violations of his release conditions. 2 The court reasoned that an above-guidelines sentence was therefore appropriate to serve the purposes of § 3553(a), and we decline to re-weigh the § 3553(a) factors.

AFFIRMED.
