San Francisco, CA Daily Water Report — September 1, 2026

Today in San Francisco, the water beckons with a solid "yes" for most activities, especially boating and surfing. With boating scoring an impressive 8.1/10, thanks to gentle winds peaking at just 15.6 knots and a modest wave height of 0.64 meters, it's a prime day to be out on the water. The surfing scene is also looking good with a score of 7.7/10, driven by consistent swells from 202 degrees at a period of 10.8 seconds, making it a fun ride for those looking to catch some waves. The air temperature will hover between 14.9 and 19.9 degrees Celsius, with a slight chill in the air due to high humidity at 89%. Visibility is clear at 14 kilometers, so while the UV index is zero, don't let the overcast skies fool you—protection is still a smart move. Fishing enthusiasts will find a decent window during the solunar major periods from 3:20 to 5:20 AM and 3:20 to 5:20 PM. The fishing score today is a respectable 7.2/10, improved from yesterday's 5.6/10, aided by stable barometric pressure at 1017 hPa and favorable solunar timings. For divers, the water temperature is a comfortable 16.7 degrees Celsius, and with diving scored at 7.1/10, conditions are better than they have been in recent days—visibility should cooperate nicely. Looking ahead, expect slightly more challenging conditions with wave heights increasing to around 1.0 meters by September 4th. If you're planning a trip later this week, aim for September 2nd for the calmest seas. To sum it up, today offers a well-rounded day on the water, with boating taking the spotlight. For the best experience, set your sails or paddle out just before sunset to enjoy the calmest waves and stunning views.
