Seal Watching at the Jersey Shore
Harbor and gray seals visit New Jersey each winter. Spot them on jetties, sandbars, and beaches from December through April.
Winter Visitors from the North
Each winter, harbor seals migrate south from New England and Canada to escape the coldest waters and ice. New Jersey's relatively mild coastal waters and abundant fish make it an attractive destination. From December through April, these charismatic marine mammals can be spotted hauled out on jetties, sandbars, and rocky shores throughout the Jersey Shore.
Sandy Hook is the most reliable viewing location, with seals regularly seen at Spermaceti Cove. But sightings are possible from Raritan Bay to Cape May. With patience, binoculars, and attention to the tides, you have a good chance of spotting seals during their winter stay.

Best Seal Viewing Locations
Sandy Hook
Northern Shore
The most reliable seal viewing in New Jersey. Spermaceti Cove and the bay beaches host hauled-out seals regularly in winter. Part of Gateway National Recreation Area.
Best Spots
- • Spermaceti Cove
- • Bay beaches near visitor center
- • North Beach (scanning offshore)
Access
Free parking in winter. Visitor center has current seal sighting info.
Tips
Bring binoculars - seals are often 100+ yards offshore. The observation deck at Spermaceti Cove is excellent.
Barnegat Inlet
Central Shore (LBI)
The inlet jetties are prime haul-out spots. Seals rest on the rocks, especially the south jetty. Barnegat Lighthouse provides a good vantage point.
Best Spots
- • South jetty rocks
- • Barnegat Lighthouse overlook
- • Inlet sandbars at low tide
Access
Park at Barnegat Lighthouse State Park. Walk the jetty carefully - slippery when wet.
Tips
Low tide is essential. The rocks are exposed and seals haul out. Bring a scope for distant viewing.
Cape May Inlet
Southern Shore
Seals frequent the inlet jetties and the rip-rap near the Coast Guard station. Seal watching cruises depart from here in winter.
Best Spots
- • South jetty near ferry terminal
- • Coast Guard pier area
- • By boat on seal watching cruise
Access
Multiple access points. The jetty walk from Sunset Beach offers good views.
Tips
Consider a seal watching cruise for closer, ethical viewing with naturalist guidance.
Stone Harbor Point
Southern Shore
Less visited than other spots, but seals occasionally haul out on sandbars. Also excellent for winter shorebirds.
Best Spots
- • Sandbars at south end of point
- • Inlet edges at low tide
Access
Park on 2nd Avenue and walk south. Beach is free in winter.
Tips
Combine with birding - the point has winter shorebirds and sea ducks too.
Manasquan Inlet
Northern Shore
Occasional sightings on jetties and near the inlet. Worth checking if you are in the area.
Best Spots
- • North and south jetties
- • Inlet sandbars
Access
Public access at both sides of inlet.
Tips
Variable sightings - check local reports before visiting specifically for seals.

Seal Watching Tips
Check the Tides
Seals haul out at low tide when rocks and sandbars are exposed. Plan to arrive 1-2 hours before low.
Bring Binoculars
Essential gear. Seals are often 100+ yards away. 8x42 or 10x42 are good choices.
Dress Warmly
Winter seal watching means cold wind. Layer up with wind-proof outer layers.
Be Patient
Seals may be submerged when you arrive. Wait and scan - heads pop up regularly.
Important: Seal Viewing Rules
Legal Requirements
- • Stay at least 150 feet from seals (federal law)
- • Never approach, touch, or attempt to feed seals
- • Do not chase seals into the water
- • Keep dogs leashed and away from seals
- • Violators face fines up to $10,000
Why Distance Matters
Seals haul out to rest and conserve energy during winter. Disturbance forces them back into cold water, wasting calories they need to survive. Repeated disturbance can cause seals to abandon traditional haul-out sites. Your respectful distance protects both the seals and future viewing opportunities.

Seal Photography Tips
Gear
Minimum 300mm lens, ideally 400-600mm. Seals are usually distant. A tripod or monopod helps with heavy lenses.
Timing
Low tide + morning light is ideal. Overcast days reduce glare on wet rocks and seals.
Settings
Fast shutter speed (1/1000s+) to freeze movement. Seals move heads frequently.
Ethics
Never approach closer than 150 feet. Let the lens do the work. Stressed seals flee into water.
Seal Watching Cruises
For a closer, more reliable experience, consider a seal watching cruise. Boats can approach haul-out sites while maintaining legal distances, and naturalists help spot and identify seals.
