Very inconsistent but with the right winds and pressure systems a good Glassy wave will be formed. Wave height can range from about six to ten feet on its day. Good atmosphere in summer but quite packed, during winter you have great freedom.
This may be biased seeing as this is my home turf but I feel that Benone is a great wave when it's on. Yes it's inconsistent but at least twice every summer and most of winter it pumps out some really gnarly waves. September swells prove to be good and at times a good ten foot in shore and twelve foot offshore can be found. Advice, wear a winter suit or suffer.
