I will be staying in Hanalei first week of August. I am currently training for a triathlon with an ocean swim (my first race with an ocean swim!) and what better place to get some practice than Kauai? I hope to swim "laps" about 30-45 minutes 2 or 3 mornings. Is there a beach that would be better suited for this? I know North Shore beaches are much calmer in summer, but guidebooks seem to suggest that many are still pretty rough for swimming, and I don't want to get in the way of surfers, etc. I would prefer to have a lifeguard nearby, as I'll be swimming alone. I will be in walking distance of Hanalei Bay but don't mind driving to another beach if it is more suited for swimming. Any suggestions?
