CatchWindow fishing intelligence

Valparaiso, Chile Daily Water Report — August 24, 2026

Valparaíso’s harbor favors the long-period crowd today. Surfing leads at 8.8 and diving at 8.5, with boating 7.4 and kayaking 7.1 close enough to matter. Fishing sits at a workmanlike 6.5 and wildlife at 6.3; sailing, on light air and a locked-in overcast, is the weak hand at 4.9. Those marks describe how the scored ingredients line up, not whether the water will treat you kindly. Open-Meteo’s current conditions and forecast describe a gray, dry Monday. Representative wind is 4 knots from the north, gusting to 8, inside a day range of 0.4 to 7.9 knots, with the sharpest gust, 20.2 knots, timed for 16:00. Waves barely change, 0.8 to 0.9 meters, calmest near 06:00 at 0.84 meters and 10.35 seconds. Swell is 0.56 meters at 12.1 seconds from 222 degrees; wind waves are a rumor at 0.02 meters. That period-over-height setup, plus almost no chop, is what lifts the surf score. The same small sea and light wind, together with 13.6-degree water sitting 1.2 degrees above average, carry the dive score. Atmospheric visibility is about 15 kilometers; that is air, not a promise of what you will see below. The useful window is late morning into early afternoon. Dawn is 10:51, sunrise 11:16, and the main solunar period runs 12:39 to 14:39, which matters for fishing along with rising pressure near 1017 hectopascals and the light wind. A lesser solunar pulse at 07:09–08:09 lands before first light. After 16:00 the gust is the day’s real tradeoff, and a 0.6 meter-per-second current toward 162 degrees is something to budget for in the harbor. Air holds 11.8 to 15.5 degrees under total cloud, 94 percent humidity, and zero UV. Tide data is unavailable. Yesterday’s reconstructed scores were already friendly—surfing 7.8, diving 8.2, boating 7.1—on even lighter 1.4-knot wind. Today the surf mark jumps a point and the rest hold or edge up. Tuesday still looks small at 0.9-meter waves but picks up a 55 percent rain chance. From Wednesday the marine forecast builds swell through 1.6 to 2.8 meters and higher, with rain often better than even money. Take the quiet water while it lasts: the best bet is a late-morning surf or dive before the afternoon gust, and before midweek’s bigger, wetter sea claims the harbor.
