Valparaiso, Chile Daily Water Report — October 5, 2026

Valparaíso is a qualified go for low-wind harbor outings, with kayaking and diving leading the board—but the 2.26 m swell means this is not a day to confuse light wind with light water. The best usable stretch is the morning through early afternoon, before the stronger gust potential and the 15:00–23:00 rain window arrive. Winds are generally slight, around 1 knot from the southeast at the representative reading, though gusts may reach 17.7 knots near 14:00. That mismatch matters: the surface may look cooperative early, while the underlying southwest swell remains substantial at 2.24 m from 240°, with a 9.85-second period. Total waves run 1.6–2.5 m, only easing toward their daily low near 23:00—after rain is expected and daylight is gone. Diving rates 7.4/10 and kayaking 7.1/10, the day’s strongest scored options, while boating and fishing each sit at 6.6/10. Those are suitability estimates, not safety clearances. The water is cold at 14.6°C, and the current is about 0.22 m/s toward 225°, so exposure, launch and recovery conditions deserve more attention than the gentle representative wind suggests. Atmospheric visibility is a generous 28.8 km, but that says nothing about underwater visibility. Cloud cover is complete, UV is nil, and the air starts cool before reaching 17.9°C. For anglers, the 08:39–10:39 solunar major period is the cleanest daylight timing, with a second major period after dark. Pressure is falling from around 1016 hPa, another reason to treat the morning as the more orderly option. Fishing is down from yesterday’s 7.9/10, while diving improves slightly from 7.2 and kayaking rebounds from 6.0. Sailing, at 4.4/10, is the weak fit: limited sustained wind and a notable gust spread make for an awkward combination. Tuesday brings a smaller 1.2–1.9 m wave range but a 94% rain chance; Wednesday turns rougher again. Thursday onward looks drier and steadier, with waves mostly 1.3–1.6 m and lighter winds. Best bet: make the morning solunar window your harbor session, but dress for 14.6°C water and give the southwest swell the respect it is plainly asking for.
