Your best bet might be to spend some time studying satellite imagery on a good size computer monitor to find some reef structures. So many free options these days: google satellite, google Earth, Bing, etc. Pick the one that has the least cloud cover and the most detail for your area. You might not see much beyond 12 feet deep or so, but in June the fish will be on or relating to the shallow reefs.
