The water here is 1.3 °C warmer than the September average of 26.8 °C. Warmer-than-normal water pushes cool-water species deeper and brings warm-water species in earlier than the calendar suggests. The water is mixed to about 67.3 m, so surface temperature carries well down the water column.

FishRadar regulations are summaries for informational purposes only. Hawaiʻi regulates nearshore and reef species by size, season and bag limit; the blue-water pelagics shown here are largely unregulated by the State, but Marine Life Conservation Districts, Fisheries Management Areas and other regulated areas impose their own restrictions, and federal Highly Migratory Species rules — including permit requirements for billfish and tuna — apply beyond state waters. Nonresidents need a Nonresident Recreational Marine Fishing License. Always check the current DAR regulations and the rules for the specific area before you fish.
