Because the Palm Beach/Jupiter area is almost all drift diving, most operators schedule night dives very infrequently: some tie the night dive schedule to only full moons. Personally, I don't think night dives in an area known for drift diving are as much fun as night dives in the keys or blue heron bridge (the only location in north Palm Beach county I like to dive at night). To me at least, it seems like you whip along so quickly as you drift northwards that once you see something interesting illuminated by your dive light, it is gone in a flash of a couple of seconds as you are carried by the current. That's my take on night dives in this area, others might disagree. I'd stick to diving in the daylight hours.
Most ops will plan dive sites around the weather and marine conditions in the area the day of the trip: so you are never guaranteed anything. With that being said, I like North and South Double Ledges, the Breakers (those are reefs), the Mizpah and related wrecks next to it. If you are going to the Breakers, see if they can make sure that you'll pass by the 'fishbowl', an area filled with so many tropicals, it feels like your diving in a fish tank. The SC goes to the sites I listed frequently. On each of the reefs mentioned, there are 4 or 5 drop zones so you'll see something different each dive.
