Cold water is not harsher than warm water, what the dive shop was probably referring to is the diving conditions in California being harsher than a typical tropical dive destination. The question is the durability of the BC under such conditions. If you get tossed into rocks will the BC have a hole. A BC should be able to float on the service with a tank attached by itself. You may need to take off the BC in order to board a dive boat.
