Fishery Profile

Fishery Overview

Waikiki / Diamond Head reef-shore fishery

A south-Oahu public reef and shore fishery from Ala Wai / Waikiki to Diamond Head. Primary targets are ulua/papio and reef fishes under DAR size and bag rules. Hanauma Bay MLCD is excluded and must not leak into this identity. Distinct from Kewalo charter water.

Static seasonal guidance · Last reviewed Aug 31, 2026

Fishery Targets

Ulua/papio are year-round DAR-managed reef targets. Exact month windows are not invented. Hanauma remains no-take and is not this destination.

Species images are AI-generated illustrations for visual reference and may simplify natural variation. Fishery records are based on the cited agency and editorial sources. About fish illustrations

  • Giant trevally illustration

    Ulua / papio

    Primary

    Caranx ignobilis

    Also called Ulua

    No seasonal pulse known

    South-shore reef and rocky point jack fishery. DAR size/bag apply. Destination month timing is not encoded as a legal season.

  • Bonefish illustration

    Bonefish (oio)

    Secondary

    Albula vulpes

    No seasonal pulse known

    Occasional south-shore flats/edge occurrence. Kaneohe Bay remains the primary oio identity.

Profile guidance — exact seasonal timing is not available for every target.

Access, Safety and Regulations

Access

Public shore access. Confirm DAR marine license and any beach-park rules. Hanauma Bay MLCD is excluded. Kewalo docks belong to honolulu-kewalo.

Primary hazards

Reef cuts, shorebreak, and crowded swimming areas. Do not enter Hanauma no-take water.

Fishery considerations

  • Tide is NOAA 1612340 Honolulu, nearby harbor tide, not Waikiki beach at-location. 51211 is nearby south-shore energy, not a surf forecast for a named break.
  • South-shore swell and trades. This is not North Shore winter surf scoring.

Regulations

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

Planning limitation

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

  • Pin is public reef/shore from Ala Wai / Waikiki to Diamond Head fishing waters. This is not Kewalo Basin docks and not Hanauma Bay.
  • Hanauma Bay MLCD (Palea Point to Paioluolu Point no-take) is excluded. Maunalua Bay FMA is a legal overlay, not this pin name.
  • 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.
