Port San Luis, CA Daily Water Report — October 5, 2026

Port San Luis gets a clear green light for low-wind water time, with boating the standout at 9/10 and kayaking close behind at 8.8/10. The sea state is modest rather than glass-flat—about 0.9 m through the day, with the calmest reading near 0.86 m around 4 AM—but the nearly absent wind is doing a lot of good work. Expect winds from roughly 0.3 to 7.6 knots, with the strongest gusts still only 8.7 knots around 3 PM. That is a friendly setup for small craft, provided the persistent swell is treated with the respect it deserves. The best broad-use window is early morning through late morning, after sunrise at 7:01 AM and around the 7:48 AM high tide. Winds should remain light, and the 0.58 m south swell at nearly 12 seconds may be more noticeable around exposed entrances and shorelines than its height suggests. For paddlers and boaters, the tradeoff is simple: benign wind does not erase moving water, and the reported ocean current is 0.25 m/s toward the northwest. Fishing rates 7/10, helped by stable pressure near 1013 hPa, light wind, and a useful morning solunar major period from 7:59 to 9:59 AM. The evening high tide at 6:29 PM arrives just before sunset at 6:44 PM, while the next major solunar period begins at 7:59 PM—after dark—so daylight anglers get the tide change but not the full evening solunar overlap. High chlorophyll is reported by CoastWatch, but it is not a fish report and should not be read as one. Diving scores 8.4/10 on the low wind, manageable waves, and warm 20.4 C marine SST. Atmospheric visibility is forecast at 17 km, but that says nothing definite about underwater visibility. Shoreline explorers have a workable midday low tide of 0.82 m at 12:45 PM, though it is not the day’s lowest water. Compared with the recent run, boating and kayaking improve slightly from October 4, while sailing remains merely moderate at 6.2/10 because there is hardly any breeze to work with. Conditions stay relatively gentle Tuesday, then waves build from Wednesday onward and become notably rougher by the weekend. Best bet: launch early, use the morning high-tide window, and enjoy the rare luxury of a quiet breeze without mistaking it for a quiet ocean.
