Fishing
Environmental planning guidance, not a catch guarantee.

Best planning window

2 hours around the next tide change

  • Manageable wind3 mph sustained wind
  • Mostly dry0% precipitation chance
  • Moving waterA rising tide can improve nearshore feeding activity
83/100 · Very 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
  • Moderate tidal exchange5.5 ft range in the next cycle
23/100 · Poor
Surfing
Offshore model guidance with nearshore uncertainty.

Best planning window

Compare swell direction, local wind and tide before leaving
