CatchWindow fishing intelligence

Santa Monica, CA Daily Water Report — October 4, 2026

Santa Monica gets a clear yes for boats and paddles today, with a qualified yes for divers and anglers: the ocean is unusually warm, small, and lightly wind-ruffled, but water-quality awareness belongs in the plan. The headline is a steady 0.6 m sea with a long 12.8-second wave period, only 0.02 m of wind chop, and a gentle current near 0.08 m/s toward the southwest. Winds are generally light, 1.6–8.4 knots, though the day’s strongest gusts reach 13 knots around 9 AM. That makes the early-to-midmorning the cleanest practical window for kayaking and boating, especially around the 10 AM low tide, when the forecast marks the day’s calmest seas. Boating rates an excellent 9.4/10 and kayaking 9.2/10—not safety guarantees, but strong indicators that the wind, waves, current, and dry forecast are cooperating. Anglers get their best timing around the 6:52–8:52 AM solunar major period, overlapping the morning high tide at 6:44 AM, with another major period from 6:52–8:52 PM after sunset. Fishing’s 6.2/10 is an improvement over yesterday’s 5.8, helped by light wind and rising pressure, but it is not a runaway bite forecast. The late-afternoon rise toward the 4:48 PM high tide offers another reasonable shore or boat window. Divers have a 7.5/10 setup, matching yesterday: warm 23.5 C marine SST, low wind, and modest seas are favorable on the surface. However, NOAA CoastWatch chlorophyll is very high at 21.58 mg/m³, indicating bloom conditions. That is not a visibility measurement, and it should not be treated as evidence of marine-life activity; check actual water clarity and local advisories before committing. The air side is hot and cloudless, climbing as high as 36.7 C, with no rain expected and atmospheric visibility around 33.5 km. Bring more water than your optimism thinks necessary. Conditions stay mostly manageable Monday, then waves build from 0.8 m Tuesday toward 1.0–1.1 m by Thursday and Friday. Best bet: launch early, enjoy the glassy 0.6 m sea before the heat and gusts get ideas, and leave the bloom question to real-time checks.
