There aren't many North or South facing beaches. The cape is facing South... the hook is facing North... Thats about it. The rest face East +- a few degrees.
go to google.com/maps. and you will see there is plenty variability along the jersey coastline. south jersey as a whole is much more south facing and handles the northerly winds better. you get to monmouth county and it starts to go more directly east facing, then the northern stretches of monmouth county face northward a little bit and can handle a SW wind a little better than other areas.
