Gulf of Thailand Wet Season: Low-Light Bites and Steady Action from Chonburi to Prachuap

Name’s Artificial Lure, checking in with your Gulf of Thailand fishing report. Down along the upper Gulf today, from Chonburi through Rayong and over toward Prachuap, we had classic wet-season conditions: hot, humid, and stormy in patches. Afternoon highs pushed into the low 30s Celsius, with that on‑and‑off southwesterly breeze bringing scattered showers and a bit of chop. Skies were mostly cloudy, which helped keep fish comfortable and up in the water column. Sun popped up just after 5:40 in the morning and slipped out a little after 6:40 in the evening along the central Gulf. That gave a nice long low‑light window, and that’s when most of the action happened. Early birds working the canal mouths and river plumes did best. Tides along the inner Gulf ran on the softer side today, with a gentle morning flood building toward mid‑day, then easing into an evening ebb. Nothing like those big spring swings, but just enough movement to get bait stirred up around points, jetty tips, and pier pilings. The bite picked up each time the current started walking instead of crawling. Inshore, anglers around Bang Saen and Sriracha reported decent numbers of **barramundi**, small **Queenfish**, and school‑size **trevally**, especially where dirty freshwater met the clearer sea water near drainage channels and harbor mouths. A few boats pushing a bit farther off Rayong picked off mixed **snapper**, **grunters**, and the odd **Spanish mackerel** on the edges of reef and rubble. No huge numbers today, but steady picking: a handful of barra per angler for those staying patient, plus by‑catch of catfish and small grouper. Offshore charter skippers out of Rayong and Pattaya mentioned scattered schools of small **tuna** and mackerel pushing bait on the surface in the late afternoon, with birds giving away the show. Lure choice was pretty straightforward. For artificials, the top producers were: - Small **metal jigs** in the 20–40 gram range, silver or pink/blue, worked fast for trevally and mackerel. - **Topwater pencils and poppers** in bone or sardine pattern at first light for Queenfish and surface‑cruising barra around structure. - 3–4 inch **soft plastic paddletails** in white or gold on 3/8–1/2 oz heads, slow‑rolled along the bottom near rocks and pilings for snapper and grouper. If you’re a bait angler, keep it simple: - Live **prawn** and small **live baitfish** like mullet or sardines are still king for barramundi and the better‑quality reef fish. - Fresh **squid strips** and **cut fish** pinned on a running sinker rig did the damage on snapper and grunter for the bottom crews. Fish activity was clearly best at first light and again in the late afternoon into dusk, especially when those short squalls passed and the pressure settled. Midday under bright sky and slack water was slow, with fish dropping deeper and following the structure tight. If you’re planning a run soon, here are a couple of local hot spots to keep on your list: - **Koh Kham and nearby reefs off Sattahip**: Good mixed bag right now—trevally, snapper, and the odd Spanish mack. Work metals and small diving minnows along current edges and drop-offs. - **Rayong nearshore reefs and artificial structures**: Reliable for snapper, grouper, and occasional cobia. Focus your drifts over rough bottom with soft plastics or squid baits just off the rocks. Closer to Bangkok, the **Bang Pakong River mouth** is still worth a dawn session for barra and catfish, especially on a rising tide pushing salt back upriver.
