CatchWindow fishing intelligence

Callao, Peru Daily Water Report — October 6, 2026

Callao is workable rather than easy-going today: fishing and diving lead the board at 6.3/10, but the 1.8–2.0 m sea keeps this firmly in the “choose your window and respect it” category, not a casual harbor day. The best daylight play is early, from dawn through the 07:55–09:55 solunar major period. Winds are forecast in the 6–9.5 knot range, before the day’s strongest gust potential builds; a 25.7-knot gust is forecast around noon. That makes the morning the cleaner option for anglers, divers, small-boat crews, and paddlers, even though the overall wave field remains substantial: 1.92 m at 11.35 seconds, driven largely by a 1.48 m swell from 199 degrees. Shorter wind waves around 0.52 m add texture rather than comfort. Fishing’s 6.3 score gets support from the morning solunar period and a second major period after dark, 19:55–21:55, though the latter is outside daylight. Pressure is falling from a representative 1011 hPa, and no tide data are available, so there is no tide-based timing to lean on. Diving also rates 6.3, helped by 24 C marine water, but surface conditions are less favorable than they were in the recent reconstructed history: diving scored 7.8 on October 4 and 6.4 yesterday. Atmospheric visibility is forecast near 17.6 km, but that says nothing about underwater visibility. Boating at 5.7 and kayaking at 5.2 reflect the sea state, current of 0.25 m/s toward 323 degrees, and gust spread. Sailing is a middling 5.9: enough breeze to work with, but the gustier midday outlook and waves demand a conservative plan. Wildlife scores highest at 6.8, with the morning major period the most practical daylight overlap. Cloud cover is heavy at 94%, rain is not indicated, and air temperatures should run 21–25.7 C. Compared with the last several days, today is a step down for boats and paddles, while fishing holds roughly steady. The next few days look gradually less lumpy, with waves easing toward 1.5–1.7 m by October 10–11 while peak winds remain mostly below 10 knots. Best bet: make an early-morning harbor plan, be off the exposed water before the noon gusts start trying to run the meeting.
