Hey Terence,
Kammabaai would probably be the best spot if you'r a beginner, it is right next to Voelklip beach. Swell range is anything from 1-4 ft. If the swell is smaller it has a prodomenently left breaking wave into the rip current, when the swell is bigger 3+ there is a right as well as a left breaking from the same peak. The two beaches (Kammabaai & Voelklip) are separated by basically only a few rocks. Be sure to stay a good distance away from the rocks boardering either side of any of these two beaches as there are very strong rips pulling out to sea.
Onrus beach would be a better bet if you'r looking for size and power, it is also a much hollower wave. There are also alot of strong currents and it picks up substantially more swell than the beaches in the Voelklip area. There are no lifeguards on duty out of season... Oh and just watch out for the locals... (haha jokes)
Hope that answers your question
