Sorry for the resurrection on this thread but felt i would expand for anyone coming in from search engines.
Pui-o / Lower cheung sha are both weather dependent, they normally start to fire around may time when the winds move from ne / e to s/sw. If there's a typhoon on I would defiantly recommend being in shape, primarily they are beach breaks BUT lower chueng sha has a point at the north end of the beach that starts working on a SW swell only and WILL barrel, any other time its just normal beach break but none the less still very very fun sucky waves, There is however a huge shark net for swimmers slap bang in the middle of the best break on lantau ( lower cheung sha ).
At lower cheung sha there is a sideways current thats pushes you from the rock into the shark net, this can get very tiring and also a bit messy if your board gets caught up and the waves are sucky.
Big wave bay / Tai-long wan, Sai kung are for the winter months when the winds are blowing from ne / e and normally very consistent during the winter months but i would recommend a steamer or spring suit depending how the water is.
Big wave bay gets very very crowded on the weekends so avoid if you dont want to be fighting for waves and in the water with complete newbies, in hong kong surfing is alot more sociable with no local-ism at all from what I have experienced.
winter months - N / NE / Sometimes SE Winds
Big wave bay - forgiving with less rips.
Tai long wan ( translated big wave bay also ), sai kung - very rippy but has the best shaped waves in hong kong, Longish hike across dragons back, but very beautiful place, and the above poster (becky) is very helpful
Summer months - S / SE / SW Winds
Pui-o - dont know much about this break, I love the pure sucky hollow fun of lower
Lower cheung sha - sidetow but when it picks up, they suck u up, are hollow and super super fun, point works on sw
Upper cheung sha - Pure beach break, breaks a little close to shore and no real banks
