Some travel books indicate the winds in Dec/Jan are significant and can make swimming on north shore beaches less than ideal (waves? rip tide?). The winds made boating (dive) difficult in St. John at that time. If we want to be close to a swimming beach, is there an area of the north shore that is protected or is there a better area to stay for sandy beach swimming that time of year? Which area is most protected for snorkeling/diving Dec/Jan-for someone who wants to dive from shore and avoid the boat?
