Since Catalina is my home, I'll add the following. Although conditions are not always ideal in June due to fog/clouds and particulates in the water, it is still much better than most mainland dive sites. The Casino Dive Park is in Avalon on the island's leeward side so swell is minimal and it is an easy entry thanks to the stairs leading into the water. Just watch out at extreme low tides since it can be a little difficult then.
The Dive Park has some great diving- good kelp forests, lots of rocky reef habitat and good sandy bottoms. And since it has been a marine reserve since the early 60's, it also has fairly abundant marine life. Why you might even run into a great white if you're lucky (don't worry, I've done well over 500 dives at that one site alone and never seen one, or anywhere else around the island while diving).
Avalon offers some options for the non-divers in the family too- beaches, restaurants, shopping (t-shirts?) so they shouldn't be disappointed. O came here in the late 60's and haven't left yet (although it's mainly because of the diving!).
Enjoy your stay. I'm in the Park almost every weekend and also weekdays that time of year. Feel free to ask if you want any information once you're there.
