It is possible the zone cooling load to peak in October. If you window is on south facing facade, the incident angle of the beam solar radiation can be close to normal (almost zero incident angle around solar noon) depending on your location, which implies high solar heat gain and hence higher cooling load due to solar. And if the other components of cooling load (internal heat gains contributions to cooling load) are smaller than solar, then in mild climate zones there is a good chance for your zone cooling load to peak in October or November. If you want to play with your model, reduce the window wall fraction of your south facing zone, and see how your zone peak cooling load and peak month changes.
