The water here is 1.5 °C warmer than the October average of 26.1 °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 60.0 m, so surface temperature carries well down the water column.

NO STATE SIZE OR BAG LIMIT. Mahimahi is not listed among Hawaiʻi's regulated marine species.
Pacific Blue MarlinRegulated Marine Species — species not listed	—	—	Jan 1 – Dec 31
NO STATE SIZE OR BAG LIMIT. Aʻu (marlin) does not appear in Hawaiʻi's regulated marine species table, which covers nearshore and reef species. Federal Highly Migratory Species rules apply offshore and an HMS permit may be required — check U.S. federal fisheries authority before you fish for billfish.
Yellowfin TunaRegulated Marine Species — ʻAhi	—	—	Jan 1 – Dec 31
NO BAG LIMIT. ʻAhi is listed in Hawaiʻi's regulated marine species table as Season: Open, Bag Limit: None. The 3-pound minimum shown against it applies to SALE, not to recreational retention. Federal Highly Migratory Species rules and permit requirements may still apply beyond state waters.

Licensing:

saltwater-recreational — residents No licence and no registration required. Recreational ocean fishing is free for Hawaiʻi residents., non-residents A Nonresident Recreational Marine Fishing License (NRMFL) is required from age 15. One day $20, seven days $40, one year $70, plus an online processing fee. Available only at fishing.hawaii.gov.

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.
