I do swim and go snorkeling in wigs. I go with synthetics with lots of wig clips sewn in. Synthetics don't tangle or do anything unexpected. They keep their style and stay exactly as they are.
The only problem I had with wigs on my vacation this summer was when they started playing a game in the pool where people (strangers) give each other head massages. I had to say no to that game.
I don't have any experience swimming in human hair wigs, but I did with human hair weaves and depending on the hair those were much more likely to do something crazy.
Don't go to Hawaii and let your wig hold you back from enjoying yourself fully.
Here are some youtube videos showing that either could work:
