Conditions are poor. Review the details below before heading out.

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.

Access, Safety and Regulations

Access

Public harbor and charter fleet at Kewalo. Nonresident marine license required. Pearl Harbor is not a public fishing destination. Hanauma Bay MLCD is excluded.

Primary hazards

Harbor traffic, heat, and open Mamalas water. Do not treat this pin as Hanauma or Waikiki reef-shore.

Fishery considerations

  • Tide is NOAA 1612340 Honolulu, at-location for the harbor. PORTS currents are inner-harbor and are not pelagic scoring.
  • South-shore exposure is not North Shore. This profile does not score wind or waves.

Regulations

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

Data Sources

Planning limitation

Coastal conditions can vary over short distances. Predictions and remote observations are planning information, not guarantees of access or safety.

  • Pin is Kewalo Basin and Honolulu Harbor entrance used by the Honolulu charter fleet. This is not Waikiki reef-shore, not Pearl Harbor, and not Hanauma Bay.
  • Current Coastal Rating is a provisional public-Beta rating. The regional methodology is still calibrating and is not formally accepted. The verdict is capped at Consider while calibration and evidence remain limited. Coastal Estimated is unauthorized.
  • Customer Current Coastal Rating is unavailable. HAWAII_TROPICAL_PACIFIC_V1 is a candidate only. PATH1 and PATH2 are not authorized now. Physical readings are not an ordinal rating.
