Scores are model-specific and are not directly comparable across water types.

Should I Go?

Trip conditions only. Target-species activity and seasonal fishery patterns are not yet included.

Consider

Trip conditions may be workable, but important cautions or data limitations remain.

High confidence in the evaluated inputs — observational coverage is partial. Required data sources were available and the key inputs were current.

Evaluates trip conditions using weather, tides, currents, waves, daylight, and active alerts.

  • Provisional public-Beta coastal rating. Methodology is not formally calibrated.
  • Numeric class: NEEDS_BOUNDED_PRODUCT_POLICY_DEFAULTS. Not an empirical fishing freeze.
  • Does not inherit Northeast or cross-region fishing thresholds.
  • Missing waves are not calm. Forecast is not an observation. Prediction is not an observation.
  • Verdict capped at Consider while calibration remains incomplete or evidence is limited.

Access, Safety and Regulations

Access

Public harbor-edge fishing includes Waterfront Park / Battery access where posted. Confirm City of Charleston rules. Folly Beach Pier is a separate ocean identity.

Primary hazards

Harbor current, ship traffic, and slick bulkheads. Folly ocean swell is not this harbor pin.

Fishery considerations

  • No qualified interval harbor-throat current identity is registered.
  • Onshore wind steepens the bar. Missing waves are not calm. Forecast is not an observation.

Regulations

Size limits, seasons, and possession rules change. Verify the current official regulations before fishing.
