CatchWindow fishing intelligence

Alameda, CA Daily Water Report — October 8, 2026

Alameda gets a clear green light for boating and kayaking, with a qualified yes for diving and a more tactical proposition for fishing. The water is unusually manageable: waves sit around 0.42 m at 8.1 seconds, with only 0.02 m of wind wave, while winds range from nearly calm to a modest 6.3 knots. That is why boating leads the board at 9.1/10 and kayaking follows at 8.5/10. It is not a safety guarantee, but it is a notably forgiving setup by the numbers. The best all-around daylight window is late morning through early afternoon, around the 11:18 AM high tide and the 10:33 AM–12:33 PM solunar major period. Expect a mild day that warms from 13.3 C to 25.2 C, no rain indicated, and light southwest wind. The tradeoff is a falling barometer near 1010 hPa, plus an evening increase in gust potential: the day’s strongest gust, 9.5 knots, is forecast around 6 PM. For anglers, the 5.8/10 score is a step down from the stronger 6.8–7.2 readings earlier this week. The late-morning major period is the cleanest timing play, while the 5:03–6:03 AM minor period overlaps the pre-dawn low-water phase and the 5:18 PM low tide lands close to the 5:03–6:03 PM minor period. Pick your timing, but do not mistake the score for a promise. Divers have a 7.6/10 day, matching yesterday’s estimate and supported by low wind and small seas. Marine SST is 21 C, with a +4.4 C anomaly versus average. Chlorophyll is very high at 5.99 mg/m³, indicating bloom conditions; it should not be treated as an underwater-visibility reading. Atmospheric visibility is forecast near 13.9 km, which is a different thing entirely. Sailing earns 6.2/10: smooth water, yes; much breeze to work with, not especially. The 0.333 m/s current toward 141 degrees remains a planning factor for paddlers and boaters. Friday turns breezier, Saturday looks notably windier with 0.5–0.8 m waves, and Sunday stays choppier before conditions ease again early next week. Best bet: launch late morning, use the high-tide/solunar overlap, and be back with the dock lines sorted before the evening gusts decide to join the conversation.
