CatchWindow fishing intelligence

Martinez-Amorco Pier, CA Daily Water Report — October 5, 2026

Martinez-Amorco Pier gets a strong green light for boats and paddles today, with fishing and diving worthwhile but more conditional. The water forecast is flat: zero wave height, swell, and wind waves throughout the day, paired with a light representative southwest wind of 2 knots. That puts boating at 9.5/10 and kayaking at 9.2/10, both the best marks in the recent CatchWindow run. The caveat is late-day wind: gusts are forecast to reach 16.1 knots around 6 PM, so the glassy-looking plan has an expiration date. The best all-around window is the morning rise, especially from dawn through the 10:58 AM high tide. The 8:05–10:05 AM solunar major period overlaps the final push of the flood, while winds remain on the lighter side and the pressure holds steady near 1012 hPa. Fishing rates 7/10, up from 6.7 yesterday and 5.8 on October 3, supported by the tide, solunar timing, light wind, and stable pressure. The evening high at 9:48 PM lines up with the 8:05–10:05 PM major period for another attractive fishing window, though it comes after the day’s strongest gust potential. For paddlers and boaters, early is plainly better: cooler air, calmer wind, and no rain indicated. It will heat up sharply, from about 18 C early to 35.3 C later, under clear skies, so water, sun protection, and a realistic turnaround time are part of the float plan. Atmospheric visibility is forecast near 56 km, excellent for seeing across the water but not a measure of what divers will see below it. Diving holds at 6.8/10, unchanged from the previous three reports. The flat surface and 21.6 C marine temperature help, but NOAA CoastWatch chlorophyll is very high at 6.44 mg/m³, a bloom-condition signal that can compromise available clarity. Treat that as a visibility tradeoff, not a wildlife forecast. Sailing is a middling 6.1/10: smooth water, yes, but not much breeze until the later gustier period. The next several days stay wave-free with dry forecasts and warm afternoons; winds peak around 5–9 knots through Friday before temperatures ease over the weekend. Best bet: launch or cast between dawn and the late-morning high tide, then be off the water before the evening breeze remembers it has a job.
