Dots are official NOAA high/low predictions. The dashed line is a bounded half-cosine estimate between adjacent extrema; it is not an official six-minute NOAA prediction and is never extrapolated beyond those points. Times are shown in the place's local timezone.

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.

84/100 · Very good
Fishing
Environmental planning guidance, not a catch guarantee.

Best planning window

2 hours around the next tide change

  • Manageable wind0 mph sustained wind
  • Mostly dry1% precipitation chance
  • 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 surface0 mph wind favors safer gear handling
  • Large tidal exchange8.4 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
