L Street Beach, Shark River - Belmar NJ

L Street Beach, Shark River is a shore accessible salt water dive site, located at Route 35 and L street, Belmar, NJ. This dive site has an average rating of 3.25 out of 5 from 4 scuba divers. The maximum depth is 16-20ft/5-6m. The average visibility is 5-10ft/2-3m.

Being in the back basin the current is less from tidal changes than in the inlet so you can get in a longer dive. The trade off is there is less to see but it is a good place to practice skills or test equipment. The site is used by some instructors for classes on weekends and can get silted out in the shallows. Best time is early evenings during the week, check the tide tables for slack high tide, anything else and viz is worse.

All diving is west of the boat ramp, between the boat ramp and Rt. 35 There is a low wall perfect for putting on the tank. Walk down the beach, not the boat ramp! Since you’ll be diving next to a boat ramp, in front of a floating fishing pier or west under the sailing school a flag is a must, NJ law requires you to surface within 25’ and boats to stay clear 50’

The second choice for an entry are the steps at the sailing school (These were locked when I was there 8/29/2012 and still locked 9/15/2013) There are also steps in from Maclearie Park. In the shallows are sea grasses, as you go deeper (max 20’) and under the boat channel it’s sand. Things you’ll see besides things lost by student divers, fishermen and boaters are the usual Jersey crabs, blueclaws, stone, hermits and horseshoe. Seabass, Sea Robins, Flounder, starfish, eels living in beer bottles, some shrimp and the occasional Seahorse. In late summer and into fall we get tropical’s, mostly butterflies, some damsels, triggers, small frogfish and I have seen squid. After the dive there is a hose near the boat ramp for washing down boats but it works for divers too (On 8/29/2012 and again 9/15/2013 that hose wasn’t there, not sure if this was because of construction or not). At the west end of the beach near the sailing school is a beach shower but it’s not always on and a bathroom that may be locked if the lifeguard is off duty.

There has been a Port-A-John next to the boat trailer parking lot lately. 9/15/2013

From NJ Scuba Divers board; The underwater landscape has totally changed. It reminded me of the ledge dives I have done in California and mexico. Lots of pilings and rock debris make a wonderful reef on the east end of the boat dock. There are hills that go from 9 ft to 17ft in just one drop. Fish are just packed under these man made ledges. For a moment I forgot I was in the bay and thought I was peeking under a hollowed out wreck.

Forget something, need air? DiversTwo is the LDS

Let me know. I am around most weekends.

Greg,Great, I’ll definitely let you know as soon as I can

I can go June 15th. Would AM or PM work better for you?
BeekeeperGreg - 5/28/2019 11:45 AM
This weekend would be a sunrise or sunset dive. High tide is around 6-7 this weekend.
The inlet is restricted after May 1st to after 5pm or before 8 am.
I will be around this coming weekend.
ChristopherBurgert - 5/28/2019 1:17 PM
I am going to be busy this weekend and June 8th I’ll be at Dutch to get some practice dives in , but I’d be up for Shark River the following Saturday.

Anyone want to do shark river anytime soon? I’ve never been there and I don’t have many dives under my belt I did do 7 dives last year at Dutch Springs, so I’m looking for a dive busy with experience at shark river.

I went scuba diving here on 5/20/2015. Average viz: Under 5ft/2m. Water temp: 66-70°F/19-21°C.

The only thing I would add is in August of 2014 - we found 6 seahorses in this area. All brown seahorses but still fun to see - if I find any this year I will get some photos or video.

Not as good as the inlet.
Plenty of crabs, star fish, flounders, ells.
Dive at high tide, but timing isn’t critical.

9/15/2013 3 mil, 72, DSS BP&W 1.5 # ankle weights in pockets. Area between beach and sailboat dock has become a jungle of seaweed and alga, lots of small fish in there. Along pilings water clears out, lots of crabs, medium size flounder, urchins but not one starfish or seahorse :( There were about 8 other divers there but didn’t see any during the dive.

I went scuba diving here on 6/29/2013. Average viz: 5-10ft/2-3m. Water temp: 56-60°F/13-16°C.
3mil, ssBP, al80. 64 degrees on the surface! The usual Jersey critters, juvi flounder, some larger in the channel, bass, hermits, blue claws and stone crabs mating, too early (cold) for starfish. About 8 other divers at the site but didn’t see any during the dive. Cannister light had a minor flood :(
