Patagonia Winter Fishing: Cold Water Tactics on the Rio Negro Coast and Limay River

I’m Artificial Lure, checking in with your Patagonia fishing report for the day. Down in **San Antonio Oeste and Las Grutas on the Río Negro coast**, the Atlantic is running cool and clear with light southwest breeze and a gentle swell. Local tide tables from Prefectura Naval show a solid morning high followed by an early afternoon drop, giving you a nice moving-water window mid‑morning and again toward dusk. Sunrise is around 8-ish, sunset close to 5:30, so your golden hours are tight but powerful. Inshore, the word from the beach casters is steady mixed bags of **pejerrey, róbalo, and some decent pescadilla** along deeper gutters. Activity has picked up on the flooding tide, with best bites an hour either side of the top. Anglers working the rocks north of Las Grutas are reporting róbalo cruising skinny water at first light, especially where there’s a bit of foam and structure. Bait-wise, the locals are doing damage with **fresh shrimp, anchoa strips, and little fillets of pejerrey** on light surf rigs. If you’re throwing artificials, think subtle: small **white or olive soft plastics on 1/4–3/8 oz jig heads**, and slim **metal spoons** when the wind picks up. Keep the retrieve slow and steady; these cold-water fish won’t chase long. Swinging inland, the **Limay and Malleo rivers near San Martín and Junín de los Andes** are settling into clear, cold winter flows. Mornings start frosty, warming just enough mid‑day to push a small feeding window. Guides on the Limay are talking about **good browns and rainbows** taken on deep nymph rigs and small streamers swung low and slow through the classic runs. With water temps down, expect the trout to hold in softer seams and deeper buckets. Nymph game is king: **size 14–18 pheasant tails, hare’s ears, and small perdigones** under a decent amount of weight. For streamers, go with **olive or black woolly buggers and small sculpin patterns**, fished tight to structure. No big hatches, but the odd midge trickle can justify a tiny dry or emerger if you see noses. Two hot spots to keep on your radar: 1. **Las Grutas – northern rocky sector and main beach gutters** Perfect if you want a mixed-bag salt session: pejerrey on light gear, róbalo close to the rocks, and the chance at a surprise pescadilla on the outside edge. Work that last hour of the rising tide and the first of the fall. 2. **Middle Limay River – classic runs below the dam** Great winter holding water for chunky browns. Hit it late morning to mid‑afternoon once the frost lifts, focus on slower seams, and get your nymphs down. If clouds roll in, switch to a darker streamer and cover water. Overall, fish are active in **short, defined windows**: salt picks up with the tide, rivers with the midday temperature bump. Pack warm layers, keep your presentations slow and natural, and don’t be afraid to downsize tippet and flies. Thanks for tuning in, and don’t forget to subscribe so you don’t miss the next report.
