Santa Monica, CA Daily Water Report — October 8, 2026

Santa Monica is a qualified go for sailing and boating, with an early-morning edge for paddlers and a solid-but-not-glassy day for diving. The water is not handing out free passes: waves run about 0.9 to 1.1 metres, with a 0.82-metre south swell at 9.2 seconds and a little 0.3-metre wind chop layered in. That is manageable for the better-scored activities, not a promise of easy launching, landing, or nearshore conditions. The cleanest timing is around dawn through mid-morning. Waves are forecast to bottom out near 0.94 metres around 7:00 AM, close to the 8:36 AM high tide, while winds begin light before building through the afternoon. By 3:00 PM, gusts are forecast to reach 15.6 knots, making the later session more workmanlike for small craft. The 2:40 PM low tide also deserves attention from shoreline explorers, who should factor in changing water movement and exposed terrain rather than treating a low number as an automatic invitation. Sailing leads the activity ratings at 7.7/10, followed by boating at 7.4 and diving at 7.0. Kayaking is 6.7, with the morning’s lower waves and lighter wind the sensible window. Fishing rates 6.2, with the 10:18 AM to 12:18 PM solunar major period the best timing cue; pressure is steady near 1010 hPa. The afternoon minor period runs 4:48 to 5:48 PM, but it arrives as winds are more likely to be up. No surfing score is supplied for this location, so there is no call here on surf suitability. Marine SST is 24 C, with a reported +5 C anomaly versus average. CoastWatch chlorophyll is very high at 21.58 mg/m³, indicating bloom conditions; that is not a measure of underwater visibility. Atmospheric visibility is forecast near 13.1 km, a separate thing entirely. Compared with the reconstructed recent history, today is breezier and less favorable for boating and kayaking than the notably light-wind stretch earlier this week, while sailing improves with the added breeze. Friday stays near 1.1 metres, Saturday remains similar, then Sunday through Monday looks more unsettled with waves potentially reaching 2.1 and 1.8 metres and rain chances rising. Best bet: launch early, use the morning high-tide window, and be off the water before the afternoon wind starts charging rent.
