Photometric observations and numerical modeling of AW Sge

•Light curves of AW Sge at superoutburst in 2013 are presented.•Observed positive superhump period compares well with values found by others.•Numerically simulated positive superhump shapes to/at superoutburst are presented.•Numerically simulated positive superhump period is within 3.5% of observed value.•Simulation suggests retrograde precession may occur before next AW Sge outburst.
