Wizard, we stayed at THE OUTRIGGER ON THE BEACH in Waikiki,you can hire boards from Kona surf shop,one block back from the beach,the hotel has a lock up board rack which is located ten steps from the beach,The hotel changes to use this service but will worth it.
We also went to Kauai and stayed at the Princeville resort,you can sup at places like Pine Trees. I don't know much about surf in July thow.
hope this helps,you lucky bugger
