CatchWindow fishing intelligence

Callao, Peru Daily Water Report — October 7, 2026

Callao is a worthwhile water day, with the strongest case for diving and fishing, but the 1.8–1.9 m sea keeps it from being a carefree small-craft outing. The decisive advantage is moderate wind rather than flat water: SE winds run 3–8 knots, while gusts build sharply enough to reach 20.8 knots around 13:00. That makes the morning the cleaner operational window before the gustier midday stretch and the 11:00–14:00 rain window. For anglers, the 7.5/10 fishing outlook gets its best timing from the 08:44–10:44 solunar major period, with a second major period after dark from 20:44–22:44. Pressure is rising toward 1014 hPa, and the light early wind is a useful part of the setup. The available chlorophyll reading is high at 1.96 mg/m³, but that is an ocean-color measure, not a promise of fish activity. No tide data are available, so there is no tide-based timing call to add. Diving leads the scored activities at 7.6/10, helped by warm 23.1 C sea-surface temperature and lighter winds early. Still, the sea state deserves respect: a 1.56 m swell from 208 degrees at 9.55 seconds is carrying most of the energy, with 0.48 m short-period wind waves layered on top. Atmospheric visibility is forecast near 21 km, but that says nothing definite about underwater visibility. Boating rates 6/10 and kayaking 5/10; both are workable only with a conservative read on exposure, gusts, and the 0.25 m/s current toward 323 degrees. Sailing is a middling 6.6/10: enough breeze to move, but a broad gust spread and active sea will keep crews busy. Compared with the last few days, fishing, diving, sailing, and wildlife scores improve, while boating and kayaking remain below the stronger conditions recorded earlier in the week. The water is also notably warmer than recent reconstructed daily values, at 23.1 C versus roughly 21–22 C. Looking ahead, winds stay near 8–9 knots through October 13 while seas gradually ease, reaching 1.5–1.7 m on October 10 before settling near 1.6–1.7 m afterward. Best bet: fish or dive early, before the midday gusts remind everyone that Callao’s harbor still answers to the sea.
