CatchWindow fishing intelligence

Santa Monica, CA Daily Water Report — October 5, 2026

Santa Monica gets a strong go for boating and kayaking today, with a clear early-day edge before the afternoon breeze starts throwing its weight around. Boating rates 9.1/10 and kayaking 8.9/10 on a day built around modest seas, no rain, and very light representative winds. The catch: those gentle-looking averages do not cancel a forecast gust to 20.8 knots around 5 PM. Plan the water time, not just the launch. The cleanest window is from dawn through late morning. Sunrise is 6:51 AM, the morning high tide arrives at 7:15 AM, and winds are expected to begin far lighter than their late-day maximum. Waves run 0.6 to 0.8 m through the day, with the calmest 0.6 m near 2 AM; the representative sea state is 0.82 m at 8.8 seconds, supported by a 0.48 m southwest swell at 11.7 seconds. That is manageable water for the highly scored small-craft activities, but it is still open water—not a permission slip to ignore exposure, traffic, or changing wind. Fishing earns a middling-to-good 6.7/10. The 7:50–9:50 AM solunar major period overlaps the morning high, while the next major period, 7:50–9:50 PM, comes after sunset and follows the 6:03 PM high tide. Falling pressure near 1011 hPa and the afternoon gust potential are the compromises. Diving is 7.3/10, helped by warm 23.7 C marine SST and relatively small waves, though atmospheric visibility of 37.5 km says nothing about underwater visibility. NOAA CoastWatch chlorophyll is very high at 21.58 mg/m3, indicating bloom conditions; that is another reason not to assume clear water below the surface. Compared with the reconstructed CatchWindow record, boating and kayaking ease slightly from yesterday’s 9.4 and 9.2, while fishing improves from 6.2. The water remains notably warm, with SST running 4.6 C above average. The next few days stay mostly dry and relatively light-wind, but seas build from about 0.7–0.8 m Tuesday to 1.0–1.1 m Thursday and Friday, with a much more unsettled range possible Sunday. Best bet: launch near dawn, enjoy the morning high-tide window, and be back in before the late-afternoon gusts decide they own the place.
