We are staying our entire trip on the north shore during our visit in late October/Early November. We've been lucky on previous visits with fairly calm surf that allowed us to swim and snorkel all north shore beaches. We are bringing relatives on this visit and i'm concerned that, if surf is higher, there will be nowhere to swim/snorkel on the north shore. All of us are comfortable in the water and average swimmers. Is there any north shore beaches one would recommend for high surf conditions? Is Tunnels or Hanalei Beach Park swimmable during this time?
