Today's Fishing Report

Generated this morning from live readings: gauge, weather model, sun and moon. A fresh report is published here every morning.

4/5Good. Solid day ahead.Stable-to-falling pressure and workable wind line things up.

Hilo Bay lines up a genuinely fishable day across the board. Today brings cloud cover, wind NE around 3 mph, rising pressure near 1016 hPa and a high of 80. Tides: high 1:21 AM and 1:10 PM, low 7:13 AM and 7:25 PM: the moving water either side of each change is when this place feeds. Water sits around 79 F for the season (estimated). With the waxing gibbous, the solunar majors run 9:06 AM-11:06 AM and 9:31 PM-11:31 PM: the windows to build the day around.

The plan, species by species

Giant trevally (ulua)Excellent

This band covers Hawaii's water for most of the year. Work rocky shorelines and outer reef drop-offs with bait at night or surface lures at first light; tracking shows ulua keep to small home ranges.

Tomorrow: Similar at 80 F with likely rain: fish ahead of the front. The solunar majors shift about 50 minutes later.Next report: Sat, Oct 24, 6:30 AMHow this report is made →

Before you go

Hawaii requires a fishing licence from age 9, from $5.00 for residents, and salt water needs its own licence here. What a Hawaii licence costs and where to buy it →

Giant trevally (ulua) illustration

Giant trevally (ulua)

Best: night and low light (IGFA)

Giant trevally (Caranx ignobilis), ulua in Hawaii, is the largest of the Indo-Pacific Caranx jacks, a reef predator that in US waters is fished mainly around the Hawaiian Islands, from shore and from boats. This band covers Hawaii's water for most of the year. Work rocky shorelines and outer reef drop-offs with bait at night or surface lures at first light; tracking shows ulua keep to small home ranges.

About this water

A bay on the east coast of Hawaii Island at Hilo, Hawaii County; NOAA tide station 1617760 (Hilo, Hilo Bay, Kuhio Bay).

Fishing Hilo Bay: the full guide

Rules written for Hilo

Hawaii's Division of Aquatic Resources (DAR) manages Hilo Harbor, the Wailoa River and the lower Wailuku River as one regulated fishing area. Hilo Harbor is the part of the bay inside the breakwater, bounded by a line from the breakwater tip southwest to ʻĀleʻaleʻa Point; the Wailoa area runs from the river mouth to the footbridge at Waiākea Pond and includes Waiolama Canal, and the Wailuku area lies between the Māmalahoa Highway and Wainaku Avenue bridges.

What the area rules allow

Anglers may fish with no more than two poles with one line each, or two handlines, and no more than two hooks or lures per line. The combined bag is 20 mullet, moi and ulua (pāpio and ʻōmilu included), no more than 15 of them moi, and mullet and moi may not be taken in their closed seasons. Nets are banned except throw nets, small ʻōpae nets and nehu nets for bait; traps and snagging are prohibited, and throw nets and spears may not be used or carried in the Wailoa River.

Waiākea Public Fishing Area

Inside Wailoa River State Park, the Waiākea fishpond, the flood control channel and Mahohuli fishpond form a public fishing area with its own rules: one line with one lure or two single hooks in tandem, and a 20-fish total of āholehole, ulua and mullet with no more than 10 mullet. Introduced freshwater game fish there require a Freshwater Game Fishing License. The park has a launch ramp, but boats may be used only for fishing, may not use fossil-fuel motors and may not run between 7:30 p.m. and 6:30 a.m.

Common questions

How many ulua and pāpio can I keep in Hilo Harbor?

They count toward a combined limit of 20 mullet, moi and ulua, including pāpio and ʻōmilu, of which no more than 15 may be moi.

Do I need a fishing license?

Nonresidents need DAR's Nonresident Recreational Marine Fishing License, and anyone taking introduced freshwater game fish at Waiākea needs a Freshwater Game Fishing License.

Can I throw a net in the Wailoa River?

Not there: throw nets and spears may not be used or carried in the Wailoa River area, though throw nets are allowed in Hilo Harbor.

How this page was made. The daily report is computed by our scoring engine from live readings; nobody types it. The written text was drafted with AI assistance from the official pages listed above, and its facts were checked against those pages by automated verification on October 8, 2026; anything that could not be verified was taken out. Pablo Ruiz Quintero sets every guideline, the data-verification system and the minimum standards a page must meet to be published, reviews page structure and approves what goes live; the responsibility is his, and the AI carries out the work. We work this way because it is how one person can keep every page current with named sources. Errors are published in the verification log; the full policy is in the editorial policy.
