Welcome to the area. I will try to answer your questions in the order you posted them. I know you are moving to Philly, but of course most of your diving will be in New Jersey. You can also dive off Delaware and Maryland, but the Jersey shore is a quick (relatively) shot down Rt. 95/195 to the shore from Philly.
1) How seasonal is the diving? What are the water temperatures like? What about viz?
The "seasonal" diving is usually April/May through September'ish. There are many divers who dive all year (me included) with the help of a drysuit. You can expect water temps in the spring to be in the 50's, and by the end of the summer, high 60's (or better) above the thermocline. Viz. ranges from 3 feet on a really bad day, all the way up to blue water 60'+ farther offshore. Normal viz. is in the 10'-25' range.
2) How do people go out diving? Are dive sites more accessible from shore or boat? Where would you recommend I start exploring.
Generally, people go out on a boat, but there is some shore diving here. If you want wrecks, a boat is the way to go. There are many boats in NJ, most are central and north Jersey, but there are a few in South Jersey. Boat trips for a two tank dive generally cost between $80-$95, and leave early in the morning (7 or 8). If the boat is quick, you should be back at the dock by noon to 1 pm. There are literally thousands of wrecks off the shore, ranging in depths from shallow (15-20' for some shore dives), medium (75'-110') and deeper. I'd recommend starting on an easy intact wreck (like the wreck of the Delaware) and work your way up to the Stolt or the Algol.
3) Are there any particular dive charters the community likes? Dive shops?
If I answered this, I'd get bashed, since there are very loyal divers to several shops and/or boats. Personally, I use the following boats: Independence II, Gypsy Blood, Blue Fathoms, Tuna Seazure, Sea Lion. They are all in the central Jersey area by Pt. Pleasant/Brielle area, but I've used many others. As for shops, personally I use the Scuba Connection in Hillsborough (they have their own pool). There are MANY excellent shops, so I would recommend contacting your "Local" dive shop once you arrive. If you are in Philly, go across the bridge into Cherry Hill where you will find "The Dive Shop". I've never use them but I know people who do and they are happy with them. They also have a dive club there.
4) Do you recommend getting wreck diver training, or can one enjoy a wreck dive without penetration? (I've done dives in an overhead environment, but do not have a wreck diver cert).
Yes, I recommend it. It is good practice anyway. Train as you dive and dive as you train. Always.

Any other particulars of NE diving, tips, advice or information would be appreciated.
Yes. Generally, you can't go on a charter to a wreck deeper than 60' without some type of redundant air supply. Some boats will permit this, but most won't. Doubles, single with pony, single with sling...etc... (spare air is not really an option). Also, a good drysuit will help you extend your dive season and also make your diving more comfortable. Most divers here are carrying at least 98cf steel tanks or bigger. Aluminum 80's are for the Caribbean, but I have seen them used here. Personally, its not for me. A good light is a must, as well as a wreck reel and at least two cutting devices.
There are a bunch of websites in NJ that are popular, like Mo's board (
NJ Scuba Divers Message Board)
Wreck Valley (
Wreck Valley Divers), NJScuba.net (
Scuba Diving - New Jersey & Long Island New York - Wreck Valley) which is VERY informative and used extensively by other sites to link from/to, and my personal favorite (because its mine), NJDive.com (
Welcome to NJDive.com) along with its forum (
New Jersey Scuba Diving Forum • Portal). NJDive posts the upcoming dives/schedules for over 30 dive shops, boats, and clubs, and has lots of good information.
Since you will be in Philly, you can train at Dutch Springs, which is a flooded quarry with lots of attractions for training. You can camp out if you want, and there are always divers to meet up with if you don't have a buddy. Going there is a guaranteed way to meet divers in your area.
As for gear, I'd recommend having your own. I saw some of your posts about diving in Northern Cal, and you make mention about shops renting gear. Some do that here too, but its not the norm. If you are taking a course from them...sure, but as a general rule, get your own.
Now I am quite sure others would like to chime in with their own advice, since this the above is just my opinion. And we all know that opinions are like a$$holes...everyone's got one and they all stink
