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.

64/100 · Fair
Fishing
Environmental planning guidance, not a catch guarantee.

Best planning window

2 hours around the next tide change

  • Moderate wind13 mph sustained wind
  • Mostly dry1% precipitation chance
  • Falling tideConditions vary by species and shoreline structure
57/100 · Fair
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
  • Large tidal exchange8.1 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
  • Short period0s dominant period
