CatchWindow fishing intelligence

San Francisco, CA Daily Water Report — October 5, 2026

San Francisco gets a clear yes for sailing and a qualified yes for boating, fishing and diving on October 5; paddlers should treat it as a more selective day. The ocean is relatively orderly, with waves holding around 0.7–0.8 m and a 0.46 m, 10.7-second swell from the west-southwest. That is not flat water, but it is a manageable-looking marine setup compared with the larger wave trend later this week. The best all-around daylight window is morning through early afternoon. High tide arrives at 9:04 AM, overlapping the 8:06–10:06 AM solunar major period, while winds are expected to remain below the day’s stronger late-evening push. A second fishing and shoreline-exploring opportunity lines up around the 2:03 PM low tide, with the 2:36–3:36 PM solunar minor period close behind. The evening high at 7:49 PM comes just after sunset, so it is more useful for those already operating in fading light than for planning a fresh outing. Sailing earns the day’s standout 9.5/10, supported by moderate WSW wind, modest gust spread for most of the day, low cloud cover and small seas. Boating rates 7.4/10 and diving 7.2/10; both benefit from the limited wave height, though neither score is a safety guarantee. Kayaking is only 5.4/10, with the 0.47 m/s current toward 212 degrees and exposed-water chop deserving real respect. Winds may reach their strongest gusts near 8 PM, up to 16.3 knots, so the late return is not the time to dawdle. Water is notably warm for the date: SST is 17.3 C, about 3.2 C above average. CoastWatch chlorophyll is very high at 5.9 mg/m³, indicating bloom conditions; that is not a measure of underwater visibility, so divers should not mistake the pleasant surface weather for a clarity forecast. Atmospheric visibility is forecast near 17.3 km, with no rain indicated and steady pressure near 1013 hPa. Compared with the recent run, fishing improves to 7/10 and sailing remains excellent, while kayaking stays near its recent middling range. Tuesday and Wednesday remain fairly gentle; waves build Thursday, then become substantially larger Friday into the weekend. Best bet: launch early, use the 8–10 AM tide-and-solunar overlap, and be back before the evening wind decides it wants a bigger role.
