CatchWindow fishing intelligence

Valparaiso, Chile Daily Water Report — October 7, 2026

Valparaíso gets a qualified go for sailors and a workable, but not carefree, day for divers and anglers; small craft should treat it as a harbor day, not a casual open-water invitation. The headline is the swell: 1.8 to 2.1 metres through the day, with a 1.92-metre west-southwest swell at 9.45 seconds. That is enough moving water to keep the coast honest even though the representative northeast wind is only 9 knots. The better all-round window comes late afternoon, when wave height is forecast to bottom out near 1.76 metres around 18:00 and winds ease toward the day’s lower range. Sailing leads the activity scores at 6.9/10, helped by usable breeze, though gusts deserve attention: the strongest forecast gust reaches 25.9 knots around midnight, and the representative 20-knot gusts mean trim and timing matter. Boating rates 5.2 and kayaking 4.3, reflecting the wave and current burden rather than a lack of wind; the current is forecast at 0.25 m/s toward 143 degrees. Diving earns 6.1/10, respectable but down from 6.8 yesterday and 7.4 on Monday. The 14.3 C marine water and persistent swell make this a choose-your-entry-and-exit-carefully proposition, not a promise of easy conditions. Fishing holds steady at 5.9/10, exactly yesterday’s score. The strongest solunar major period is 10:23 to 12:23, with another from 22:23 to midnight; without tide data, those are timing cues rather than a complete fishing plan. Wildlife also sits at 6.4/10, unchanged from the last two days. Cloud cover is forecast at 100%, with rain possible from midnight through 09:00, although representative precipitation is zero. Atmospheric visibility is forecast at 25.4 km, but that says nothing about underwater clarity. Air temperatures run 11.9 to 17.7 C, and the rising pressure—1012 to 1017 hPa—adds a little weather stability after the morning dampness. The next few days look progressively less lumpy: waves ease to 1.5–1.8 m Thursday and 1.3–1.5 m Friday, with light winds, before rain chances rise again early next week. Best bet: sail the later-afternoon harbor window, when the sea is at its least tall and the day has shed its morning drizzle.
