CatchWindow fishing intelligence

Martinez-Amorco Pier, CA Daily Water Report — August 27, 2026

Today at Martinez-Amorco Pier, the clear winner is kayaking, with boating close behind—both scoring in the high 8s thanks to a glassy surface that virtually never happens this time of year. We’re looking at a rare, near-zero wave day, with no measurable swell or wind waves and a representative wind of just 3 knots from the southwest. The ocean is essentially flat, and that calm holds all day: the wave height never budges from zero through the entire forecast window. If you paddle or run a small boat, this is about as ideal as coastal conditions get—no chop, no groundswell bump, just still water and 23.1°C sea surface temperature. The tradeoff is that fishing drops to a 6/10. The solunar minor period aligns with moonrise around dusk, and the major period hits midday, but the high chlorophyll reading—6.44 mg/m³, solidly in bloom territory—suggests thick plankton that can scatter bait and make fish less concentrated. The wind stays light enough to drift quietly, but the lack of tide data leaves a blind spot: without knowing the stage or velocity of the current, it’s harder to time a productive drift. Wildlife viewing scores a solid 7.2, and with dawn breaking at 6:07 and the surface this placid, early morning could reward patience even if the fish aren’t stacked up. Surfing and sailing are non-starters. Zero wave height means no ride for surfers, and though the sailing score is 4.6, the wind maxes out at just 8.3 knots before fading—not enough for consistent planing. Diving lands a 6.8, buoyed by warm water and calm surface conditions, but the chlorophyll bloom likely cuts underwater visibility; atmospheric visibility of 43.5 km has no bearing on what you see below. Compared to recent days, this is a significant shift. The past five reports showed consistent diving scores of 6.8, but wave heights were equally flat on August 25 and 26, and wind was similarly light. The standout difference today is the higher air temperature—up to 33.3°C in the afternoon—paired with stable barometric pressure at 1013 hPa. That heat, combined with zero wave action, makes for a sweaty but serene afternoon on the water. Looking ahead, the marine forecast stays flat through September 2, with no wave activity at all. Winds will pick up slightly—peak gusts near 11 knots by midweek—but nothing that would disrupt a paddle or a cruise. The air cools off after today, with highs dipping into the low 20s by Monday. Your best bet: launch at dawn, glide across a mirror-flat bay under a waxing gibbous moon, and soak up a stillness that won’t last.
