East
Grouville Bay (Longbeach)
Broad east-coast sweep with long sand at lower water and a big tide range that can make it excellent for open beach walks.

Apple MapsCoastal context
This coast is treated as a broad tidal flat, so low tide opens a lot more walkable ground but the incoming tide matters more. South and east Jersey are treated as lower-lying with larger visible tidal change.
Best times today
Dog walk
Why this best time
Good dog-walk option. This is one of the more practical dog-walk choices. The shoreline has usable room now.
08:45–10:45
Family
Why this best time
Family conditions are good overall. This is one of the easier family picks. Access, parking, and facilities support a family visit. Wind comfort matters here. Strong gusts make exposed beaches feel rougher than the main wind reading suggests.
13:45–15:45
Low tide walk
Why this best time
Excellent low-tide walk because the tide is low enough to open a proper stretch of shore and the shoreline shape suits a longer low-water walk. The falling tide should open a little more room.
08:45–10:45
Paddleboard
Why this best time
Paddleboarding conditions are poor because the E wind is too lively for easy paddling, the water is more exposed or less settled, and there should be enough useful water around the launch window. Strong gusts make exposed beaches feel rougher than the main wind reading suggests.
14:45–16:45
Picnic
Why this best time
Good picnic option. The current weather is fairly workable for staying put. Access and nearby basics are stronger here.
08:45–10:45
Rockpooling
Why this best time
Good rockpooling option because low water is exposing more shore and the shoreline has enough rock, stone, or mixed ground to make pools more likely. Strong gusts make exposed beaches feel rougher than the main wind reading suggests.
09:45–11:45
Sheltered today
Why this best time
Poor sheltered choice today because the E wind still reaches it and the bay is only partly sheltered.
08:45–10:45
Sunset
Why this sunset score
A mixed sunset pick because the sunset angle is decent here, but not as strong as the western headlands. Cloud or rain may flatten the light.
20:40–21:26
Surf
Why this best time
Surf setup is poor because the E wind is likely making it messy, this beach is not one of the stronger surf-exposed spots, and the tide is away from the better surf window.
08:45–10:45
Swim
Why this best time
Fair swim option because the tide lines up well for swimming and wind exposure takes some of the comfort away. Strong gusts make exposed beaches feel rougher than the main wind reading suggests.
14:45–16:45
Walk
Why this best time
Good for walking now because the tide is low enough to expose plenty of walking space. The falling tide gives you a little more room.
08:45–10:45
Sunrise
A excellent sunrise pick because this coast catches early light well. Some cloud could still make the light interesting.

Surf
Surf setup is poor because the E wind is likely making it messy, this beach is not one of the stronger surf-exposed spots, and the tide is away from the better surf window.
Swim
Poor swim option because the tide is outside this beach's strongest swim window and wind exposure takes some of the comfort away.
Walk
Good for walking now because the tide is low enough to expose plenty of walking space. The falling tide gives you a little more room.
Hazard notes
The sea moves across a wide flat here, so walking distance and return timing matter. Easterly wind adds a lot of exposure.
