Valparaiso, Chile Daily Water Report — October 8, 2026

Valparaíso is a good-go day for powered boating, kayaking and diving, with a useful but not effortless harbor sea state. The headline is light wind—generally 0.5 to 6.1 knots—paired with 1.5 to 1.8 metres of wave height and a 1.64-metre swell from 250°. That is enough moving water to demand attention around exposed entrances and shorelines, even though the breeze itself is mostly cooperative. Boating leads the board at 7.7/10, kayaking follows at 7.5, and diving rates 7.9. Those are suitability estimates, not safety clearances, but the combination of low wind, a modest 0.11 m/s current toward 207°, and no meaningful wind-wave component gives small craft a better deal than yesterday. The tradeoff is the swell: it will remain the feature to manage, particularly for launching, landing and any work close to hard edges. Conditions ease only slightly late, with the day’s calmest wave height near 20:00 at 1.52 metres—after sunset at 19:53. For anglers, the 6.2/10 fishing score points to a decent rather than standout day. Pressure is rising from around 1015 hPa, and the strongest solunar window runs 11:09 to 13:09. A smaller evening window falls from 17:39 to 18:39. The 14:00–17:00 rain window is the awkward middle shift, despite representative precipitation sitting at zero. Air temperatures reach about 17.1°C, while sea-surface temperature is near 15°C; dress for the water, not the afternoon air. Diving has improved sharply from yesterday’s 6.1/10, while boating has rebounded from 5.2 and kayaking from 4.3 as winds have backed off. Atmospheric visibility is forecast near 13.26 km, but that is not a measure of underwater visibility. Chlorophyll is moderate at 0.55 mg/m³ and should not be read as an activity forecast. The next three days look progressively easier on the sea: waves settle to roughly 1.2–1.5 metres through Sunday, with the lightest winds forecast Sunday. Best bet: launch early, use the 11:09–13:09 fishing window if that is your plan, and treat the swell—not the wind—as the boss of the harbor.
