San Francisco, CA Daily Water Report — August 28, 2026

Today, San Francisco offers a mixed bag for water enthusiasts, with a few activities shining brighter than others. Sailing leads the pack with a solid 7.9/10, thanks to consistent winds from the west at 9 knots, gusting to 13. The partly cloudy skies and mild temperatures hovering around 15°C make for a comfortable day on the water. Surfing enthusiasts will also find decent conditions with a score of 7.3/10, supported by 1-meter waves and a manageable swell direction from 289 degrees. Fishing scores a respectable 6.5/10, bolstered by the full moon's influence and favorable solunar periods, though you'll have to contend with high chlorophyll levels at 5.9 mg/m³, indicating a bloom. Divers can enjoy a 6.8/10 scenario, with calm waters peaking around 11:00 AM, and a sea surface temperature of 16.3°C, slightly above the average. On the downside, kayaking is less appealing today with a score of 4.3/10, largely due to the ocean current moving at 1.9 m/s. Boating doesn't fare much better, scoring 5.6/10, as the combination of wind, waves, and strong currents might make for a choppy ride. Compared to recent days, today's conditions are a slight improvement for sailing and surfing but a step back for kayaking and wildlife viewing, which has dropped from yesterday's high of 8.4/10 to 7.3/10. Looking ahead, the next few days promise more of the same in terms of weather stability, with temperatures ranging from 13.3 to 21.1°C and no significant rain in sight. The waves are expected to mellow out as we move into September, providing potentially better conditions for kayaking and diving. Best bet for today? Hoist the sails and enjoy the breeze; it's a day tailor-made for sailing.
