Alameda, CA Daily Water Report — October 7, 2026

Alameda gets a clear green light for small-craft time today, with boating the standout at 9.3/10 and kayaking close behind at 8.7/10. This is a notably gentle water day: waves hold near 0.3 m, the representative wind is just 3 knots from the NNE, and even the day’s strongest gusts only reach 6.8 knots around 5 PM. That is not a safety guarantee—tide and current still deserve their usual respect—but it is a very forgiving setup by recent standards. The best all-around daylight window runs from after sunrise through the late-morning high tide at 10:43 AM, when the water remains small and winds are light. Anglers have a useful overlap with the 9:46–11:46 AM solunar major period and the high tide; fishing rates 6.8/10, slightly below the 7.2 posted on October 6 but still respectable under stable 1012 hPa pressure. A second solunar major period arrives from 9:46 PM to 11:46 PM, overlapping the 10:29 PM high, though it is obviously a different proposition after dark. For paddlers and boaters, the afternoon remains workable, but the 4:30 PM low tide and the day’s comparatively stronger late-day breeze make the morning the cleaner choice. Sailors get enough breeze for a 6.4/10 day, but should not expect much sustained drive; this is more light-air patience than proper sailing weather. Diving scores 7.6/10 on the calm surface, warm 20.8 C marine SST, and available clarity inputs, but atmospheric visibility of 14.6 km says nothing about underwater visibility. Chlorophyll is very high at 5.99 mg/m³, indicating bloom conditions, so water clarity may be a tradeoff despite the flat surface. The water is exceptionally warm relative to average, with SST running 4.2 C above normal. Compared with the recent run, today is calmer than October 4’s 4.9-knot wind day and nearly matches the excellent boating and paddling pattern of the last week. Thursday stays mild and small, then conditions trend breezier and lumpier Friday through Sunday, with waves building to 0.6–0.8 m Saturday before easing early next week. Best bet: launch after dawn, make the 10:43 AM high tide your turnaround marker, and enjoy one of the week’s easiest rides before the weekend stiffens up.
