Are you asking about shore dives off Kona or Oahu?
Kona gets the same trade and prevailing winds as Oahu, so dive sites vary depends on the wind directions and surf conditions. Especially in the Spring time. Our week was met w some big swells in Kona in Jan (20-25') and just about everywhere was off limit except for surfing, that is if you are a good surfer in that kinda waves. You must have gone to Oahu in the summer last year to dive at Sharks cove, what was it like? Hanauma Bay diving is hard to beat tho, go off to the left side just before the breakers, further away from the snorkelers, that area is got some really cool stuff. Look for the Hawaii flasher wrasses. I am partial to the solid black long nose butterfly.
