Fishing, Crabbing & Surfing Analysis

These scores use the available tide, wind, and marine data. They do not predict catches, report local activity, or replace safety notices.

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

Best planning window

2 hours around the next tide change

  • Manageable wind5 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 surface5 mph wind favors safer gear handling
  • Large tidal exchange8.6 ft can increase current around gear
60/100 · Fair
Surfing
Offshore model guidance with nearshore uncertainty.

Best planning window

Compare swell direction, local wind and tide before leaving

  • Usable offshore swell5.0 ft NWS forecast waves
  • Short period7s dominant period
  • Nearshore uncertaintyOffshore model conditions are not the same as breaking-wave height at this beach
