This is Artificial Lure with your coastal Korea fishing report.
Along the South Korean coast today we’ve got a fairly classic late‑spring pattern. The West Sea (Yellow Sea) side around Incheon and Gunsan is running a moderate tidal swing tied to the mid‑month moon: low in the early morning, strong flooding mid‑day, and a solid evening ebb. Down on the South Sea coast—Tongyeong, Yeosu, and Geoje—the tide’s pushing a bit harder, with the best current lining up a couple hours after sunrise and again toward dusk. Expect sun up around 5:20 a.m. and sunset close to 7:40 p.m. along most of the southern coastline. Weather is mild: light to moderate south‑southwesterly winds, a bit of haze, and stable barometric pressure—good conditions for consistent bites, especially where current and structure meet.
Water temps are sitting in that sweet late‑spring band: mid‑teens Celsius on the West coast, upper‑teens and nudging 20°C around Busan, Geoje, and the Tongyeong archipelago. That’s turned on the rockfish and sea bass, and the flatties are sliding up on the sandbars and channel edges.
From the West Sea charter captains out of Incheon and Daebu Island, reports this week have been solid for olive flounder and Korean flounder on the afternoon flood, with boats commonly netting 20–40 keepers on a mixed crew, most in the 40–55 cm range. Closer to shore, black rockfish numbers are steady around breakwaters, especially where there’s kelp or concrete block. A few early‑season cutlassfish have started to show farther south near Mokpo night boats, though the real rush is still ahead.
On the South Sea and East Sea, Busan and Geoje anglers are seeing active seabass around harbor lights and rocky shorelines. Night plugs around Busan North Harbor and the outer Taejongdae rocks have produced fish in the 50–70 cm class, with a couple larger ones reported near sunrise when the bait gets pushed tight to the rocks. Jigging charters off Geoje and Namhae are reporting mixed bags of rockfish, greenling, and decent flounder on slow‑pitch metal in 60–80 m. East coast breakwaters like Ulsan and Pohang have given up horse mackerel and chub mackerel on small sabiki rigs, with kids filling buckets during the evening runs.
Lure choice: for shore‑based seabass, keep it simple—110–130 mm minnow plugs in natural sardine, ayu, or clear with a bit of flash, and 20–30 g metal jigs you can bomb into the wind. Around the rocks, 3–4 inch soft plastics on 7–14 g jigheads—shrimp or small baitfish colors—are doing work on rockfish and greenling. On the flounder side, boat anglers are sticking with the usual: 30–60 g bottom rigs tipped with live shrimp, live gobies, or small baitfish. If you’re land‑based, a simple Carolina rig with a 2–3 inch Gulp‑style scented grub dragged slowly across sandy pockets near harbor mouths will surprise you.
Bait anglers are still king when it comes to consistency. Around most piers, raw shrimp chunks, ragworm, or live sandworms on small size 6–10 hooks will pull in rockfish, scorpionfish, and the occasional flounder nosing close to structure on the flood.
A couple of hot spots to keep in mind:
First, the Tongyeong area: the island channels between Tongyeong city and Hansan Island are running good current right now, and the rocks there have been giving up quality rockfish and a few seabass on the evening tide. Small boats drifting the channel edges with soft plastics or light jigs are doing especially well.
Second, Geoje’s northern coast around Gohyeon and the surrounding breakwaters. The mix of harbor lights, drop‑offs, and steady current has produced seabass after dark and flounder sitting just off the sand transitions during the day. Cast diagonally across the current, let your lure sink, and work it back with short, sharp lifts.
Overall fish activity is best at first light and the last two hours of daylight, especially when those windows overlap with moving water. Midday can still produce if you target shade lines, deeper channels, or wind‑blown points where bait stacks up.
