CatchWindow fishing intelligence

Redwood City, CA Daily Water Report — August 27, 2026

Today’s a strong day for getting out on the water, with boating and kayaking scoring in the low 8s, diving not far behind at 7.4, and fishing a respectable 6 out of 10. The flat calm—waves holding at a dead zero all day—creates almost ideal conditions for paddlers and powerboaters, though that same stillness limits the surf to a 4.5. Best windows fall in the late morning to early afternoon, when the northerly wind hangs around 4 knots and the air pushes toward 28°C. The afternoon gusts to nearly 17 knots could ruffle things for sailors, whose score settles at 5.2, but for flat-water pursuits, the wind won’t be a problem. A couple of things to keep in mind. The water is notably warm at 16.9°C, about 1.4 degrees above average, but that’s matched by a very high chlorophyll reading of 6.48 mg/m³. That bloom signals active biology and could drop underwater visibility for divers—worth checking your line of sight before committing to a site. Fishing scores, while decent, are tempered by the overcast sky and the absence of strong tidal movement; the solunar period from 11:33 to 13:33 offers the best shot at activity, but don’t expect a frenzy. Comparing with recent days, today’s calm mirrors the light-wind conditions of August 25th and 26th, when boating and kayaking also scored well, though today’s fishing score slips slightly from yesterday’s 7.9. The surf remains stuck at 4.5, unchanged for the past week, as the swell simply isn’t there. The diving score holds steady at 7.4, consistent with the last four days, suggesting the underwater profile hasn’t shifted much. Tomorrow’s forecast brings similar flat seas, light winds, and a slight cooldown, with peak gusts around 10 knots. The rest of the week stays dry and calm, holding steady for boaters and paddlers. Best bet: Get the kayak or skiff out between 10 a.m. and 2 p.m., when the light breeze and glassy water make for the smoothest ride.
