CatchWindow fishing intelligence

San Diego, CA Daily Water Report — October 4, 2026

San Diego gets a firm green light for boating, kayaking, and diving today, with a small but real asterisk: pleasant water does not erase the need to respect the tide, swell, and heat. The marine setup is notably gentle. Waves are holding around 0.7–0.8 m, with a 0.62 m southwest swell at nearly 12 seconds and almost no wind-wave chop. Representative winds are a light 4 knots from the SSW, though gusts could reach 12.2 knots around 10 AM. That combination supports the day’s strongest scores: boating 8.9/10, kayaking 8.3, and diving 8.2. Marine SST is 23.4 C, running 2.8 C above average, while the available atmospheric visibility forecast is 14.4 km; that is useful topside, not a promise of underwater visibility. For the smoothest launch-and-return rhythm, the early morning is hard to argue with. High tide arrives at 6:38 AM, close to the 6:48–8:48 AM solunar major period, before the late-morning low at 10:54 AM. The afternoon rising tide builds toward a 1.68 m high at 4:49 PM, and the second major solunar period runs 6:48–8:48 PM, after sunset at 6:32 PM. Fishing rates a respectable 6.4/10, helped by those timing windows, light wind, rising pressure, and manageable seas—not a guarantee, just a decent day to put in patient hours. Sailing also scores 6.4/10, which makes sense: the water is cooperative, but the breeze is more “polite suggestion” than dependable engine. Wildlife is 6.6/10, with the late-morning low tide and lighter winds offering the better shoreline-exploration setup. Compared with CatchWindow’s recent estimates, boating matches yesterday’s 8.9, diving holds at 8.2, and kayaking is nearly unchanged from 8.4. Fishing improves slightly from yesterday’s 6.0, while sailing gets a modest lift from 5.8. The next two days stay mostly dry and light-wind, but seas trend upward from 0.7–0.9 m Monday to 0.9–1.0 m Tuesday, then build further later in the week. Best bet: launch early, enjoy the tidy morning water, and be back with plenty of margin before the day’s heat and afternoon tide take over.
