NOAA provides official high/low predictions for this subordinate station. The dashed curve and tide-now height are bounded half-cosine estimates between adjacent official extrema; no values are extrapolated beyond them.

Fishing, Crabbing & Surfing Analysis

Transparent environmental scores based on tide, wind and marine conditions. These are not user reports, catch guarantees or substitutes for official closures and safety guidance.

78/100 · Good
Fishing
Environmental planning guidance, not a catch guarantee.

Best planning window

2 hours around the next tide change

  • Manageable wind3 mph sustained wind
  • Moving waterA rising tide can improve nearshore feeding activity
71/100 · Good
Crabbing
Conditions are secondary to seasons, closures and safety.

Best planning window

Near slack water, if the marine area is open

  • Regulations requiredConfirm the marine area is open before setting gear
  • Calm surface3 mph wind favors safer gear handling
  • Large tidal exchange10.2 ft can increase current around gear
23/100 · Poor
Surfing
Offshore model guidance with nearshore uncertainty.

Best planning window

Compare swell direction, local wind and tide before leaving

  • Limited swell0.0 ft NWS forecast waves
  • Wave period not publishedThe surf score uses available NWS wave height and local wind only
  • Nearshore uncertaintyOffshore model conditions are not the same as breaking-wave height at this beach
