CatchWindow fishing intelligence

Port San Luis, CA Daily Water Report — October 4, 2026

Port San Luis gets a clear green light for boating and kayaking today, with a caveat: the ocean is manageable, not flat. Boating leads the board at 8.8/10 and kayaking follows at 8.5/10, supported by very light northwest wind, no rain, and a steady 0.9–1.0 m sea. The representative wave period is a respectable 11.5 seconds, so expect some organized motion rather than wind-chop chaos. The cleanest practical window is early through late morning, after dawn at 6:35 AM and around the 7:11 AM high tide. Winds remain light for most of the day, though they build to their strongest point around 3 PM, with gusts near 8.4 knots. That is hardly a gale, but it is enough to make an otherwise easy paddle feel more like a small administrative dispute with the afternoon. The 11:26 AM low is a modest one at 0.98 m, followed by a stronger rise toward the 5:14 PM high of 1.62 m. Anglers have a respectable 6.9/10 day. The 7:01–9:01 AM solunar major period overlaps the morning high, making it the standout fishing window; the evening major period runs 7:01–9:01 PM, after sunset but within dusk’s tail end at 7:11 PM. Rising pressure near 1013 hPa, light wind, and mild seas support the score, though conditions are not a promise of a bent rod. Sailing rates 6.2/10: smooth water and clear skies are pleasant, but the breeze is limited, so sailors seeking powered-up conditions may find more patience than propulsion. Wildlife scores 7.1/10, with the late-morning low-tide transition and light wind offering the better shoreline-exploration setup. Atmospheric visibility is forecast near 25.5 km, excellent for looking around, but it says nothing about underwater visibility. Diving is not scored today. Compared with recent CatchWindow reports, boating and kayaking improve from yesterday, while fishing also ticks up. The marine temperature is forecast at 20.3 C, warmer than the recent 19.1 C readings. Monday and Tuesday stay comparatively gentle near 0.9–1.0 m, then seas build from Wednesday onward, reaching 1.5–2.0 m by Saturday. Best bet: launch early, use the morning high tide, and be back with the boat rinsed before the afternoon breeze starts asking questions.
